18Ni-8Co-3.6Mo-0.5Ti is a precipitation-hardening maraging steel engineered for ultra-high strength with excellent toughness and dimensional stability. This alloy is widely deployed in aerospace structures (landing gear, fasteners, critical forgings), tool steels for high-performance dies, and defense applications where weight savings and damage tolerance are critical. Engineers select maraging steels over conventional high-strength alloys when damage-tolerant fracture mechanics, low distortion during heat treatment, and repeatable performance in critical load-bearing roles are essential—making it the reference material for applications where strength-to-weight ratios and reliability cannot be compromised.
18Ni-9Co-2.8Mo-0.8Ti is a precipitation-hardening maraging steel engineered for ultra-high strength with exceptional toughness and ductility. The nickel-cobalt-molybdenum-titanium system produces a martensitic matrix strengthened by intermetallic precipitates formed during low-temperature aging, eliminating the brittleness typically associated with ultra-high-strength steels. This alloy is employed in aerospace structures, pressure vessels, tooling, and sporting equipment where the combination of extreme strength, damage tolerance, and fatigue resistance justifies the material cost; it is preferred over conventional high-strength steels and some titanium alloys when weight savings and fracture toughness must both be optimized.
19Cr-4Ni duplex stainless steel is a lean duplex stainless alloy combining chromium and molybdenum for corrosion resistance with a dual-phase microstructure (austenite + ferrite) that enhances strength and toughness. It is widely used in oil and gas pipelines, desalination plants, chemical processing equipment, and marine structures where resistance to pitting and stress-corrosion cracking is critical and cost must be controlled relative to super-duplex grades. Engineers choose this alloy when corrosion resistance and strength must be balanced against material cost and machinability, offering a middle ground between austenitic stainless steels and more expensive duplex variants.
19Ni-14Co-1.8Ti maraging steel is an ultra-high-strength iron-nickel alloy hardened by precipitation of intermetallic phases rather than carbon, resulting in a martensitic matrix with exceptional strength and toughness at relatively low carbon content. It is used in demanding aerospace, defense, and precision engineering applications where extreme strength-to-weight ratios, dimensional stability, and fracture resistance are critical, such as rocket casings, landing gear, and high-performance tooling; this alloy family is preferred over conventional tool steels and other ultra-high-strength materials when designers need to combine very high yield strength with adequate ductility and minimal distortion during heat treatment.
19Ni-15Co-1.8Mo-1.9Ti is a precipitation-hardening maraging steel engineered for extreme strength with minimal ductility loss, achieving hardness through intermetallic phase formation rather than carbon content. Its nickel-cobalt-molybdenum-titanium system is deployed in aerospace structural components, defense systems, and precision tooling where weight savings and damage tolerance are critical; engineers select maraging steels over conventional high-strength steels when fatigue resistance, toughness, and dimensional stability during heat treatment are equally important to raw strength.

316L stainless steel printed by metal binder jetting is the low-carbon, molybdenum-bearing austenitic steel formed by depositing liquid binder onto a powder bed, with no melting during the build. The green part is fragile and porous, so it is depowdered, debound and sintered, and sintering provides its final density. Parts shrink considerably in sintering, so geometry is compensated and slender features may need setters to limit distortion. Residual porosity and surface roughness are typically higher than in wrought material, but fusion-type residual stress is avoided. It is used for corrosion-resistant fittings, housings and fluid-handling parts with complex shapes.
Desktop Metal 316L Stainless Steel (Shop System) is that maker's grade of low-carbon austenitic 316L stainless steel for binder jetting, used in the sintered condition. Parts are printed as green bodies of binder-held powder, then depowdered and furnace-sintered. They shrink substantially as they densify, so designs must allow for shrinkage and sagging. The sintered structure is equiaxed austenite with some residual porosity, more uniform between build directions than laser-melted 316L, and it needs no supports and carries little residual stress. Typical uses are production runs of small brackets, fluid fittings, hardware and tooling parts that would otherwise be machined, cast or metal injection molded.

316L stainless steel made by bound metal deposition is the low-carbon, molybdenum-alloyed austenitic grade, printed from metal-filled polymer filament and then debound and sintered into metal. The green part is printed oversize to allow for sintering shrinkage, and supports or a ceramic interface layer are often needed to limit distortion in the furnace. Sintered parts are largely dense but can keep fine residual porosity, with layer lines and some anisotropy between build directions. Critical surfaces are usually machined or polished. Typical uses are corrosion-resistant fixtures, tooling, housings and low-volume fluid-handling parts.
Desktop Metal 316L Stainless Steel (Studio System 2) is the maker's 316L austenitic stainless steel for bound metal deposition, printed from rods of metal powder in a polymer and wax binder and used in the sintered condition. Parts are extruded oversize, then debound and sintered, shrinking toward near-full density, with a ceramic interface layer letting supports separate after sintering. Sintering rather than melting gives an equiaxed austenitic structure free of melt-induced residual stress, but leaves some porosity, visible layer lines and a surface that often needs machining on critical faces. Parts serve as prototypes, jigs, fixtures and low-volume functional parts.

Markforged 316L Stainless Steel is a sintered grade of low-carbon, molybdenum-bearing austenitic stainless steel made by Bound Metal Deposition (BMD), a material extrusion process. Metal-powder-filled polymer filament is extruded, then the part is debound and furnace sintered, shrinking substantially, so it is printed oversize. The sintered part has an equiaxed austenitic structure with some residual porosity, low residual stress, visible layer lines and somewhat direction-dependent properties, so critical surfaces are usually machined. It is used for jigs, fixtures, tooling, brackets and low-volume corrosion-resistant parts.

316L stainless steel printed by fused deposition modeling is the molybdenum-bearing austenitic grade made from filament in which fine steel powder is bound in a polymer. The extruded green part is debound and then sintered to densify the metal, so the route resembles metal injection molding more than melt-based metal printing. Layer and infill structure leave some anisotropy between build directions, sintering shrinks the part substantially, and residual porosity and a layered surface are typical; overhangs need supports. It is used for jigs, fixtures, tooling, functional prototypes and low-volume corrosion-resistant parts with complex geometry.
BASF Forward AM Ultrafuse 316L is a filament of 316L stainless steel powder in a polymer binder, printed by fused deposition modeling into a green part that becomes solid metal only after debinding and sintering. The binder is removed catalytically, and sintering then densifies the part with substantial shrinkage that the design must compensate, leaving an austenitic structure with some residual porosity. Parts show layer lines and somewhat lower properties across layers than along them, and critical surfaces usually need machining. The grade is used for prototypes, tooling, jigs, fixtures and low-volume corrosion-resistant parts.

BASF Forward AM Ultrafuse 316L, sintered, is 316L austenitic stainless steel printed by material extrusion from a filament of metal powder in a polymer binder, then debound and sintered. The binder is removed from the printed green part, typically by catalytic debinding, and furnace sintering fuses the powder into a near-dense metal part, with substantial shrinkage that the print is scaled up to offset. Sintered parts keep the layer texture of extrusion and some residual porosity, and surfaces that need tight tolerances are usually machined. Typical uses are jigs, fixtures, tooling, brackets and low-volume functional parts that need the corrosion resistance of 316L.

316L stainless steel printed by laser powder bed fusion is the low-carbon, molybdenum-alloyed austenitic grade, built by selectively melting fine powder layer by layer. Rapid solidification gives a fine cellular sub-grain structure and columnar grains growing along the build direction, so horizontal and vertical builds can differ. Parts carry high residual stress, so they are built on a plate with supports and stress relieved before removal. Surfaces are rough as printed and are often machined or polished, and small pores can remain unless the part is densified. Typical uses are corrosion-resistant manifolds, heat exchangers, fluid-handling parts, tooling and lightweight brackets.

Parts need supports on overhangs and are usually stress relieved, cut from the build plate and machined or polished where the rough as-built surface matters. Printed parts serve as corrosion-resistant manifolds, valve bodies, heat exchangers and complex industrial components.

316L stainless steel made by wire-fed laser directed energy deposition is the low-carbon, molybdenum-bearing austenitic grade built up bead by bead as a laser melts wire onto a substrate. The deposit solidifies as coarse columnar grains along the build direction, so properties can differ between build and travel directions, and thermal cycling leaves residual stress and distortion. Lack-of-fusion porosity can occur between beads if parameters are poorly tuned. Surfaces are rough and wavy, so functional faces are usually machined. Typical uses are near-net-shape preforms, large corrosion-resistant parts, cladding, and repair of existing components.
Meltio Stainless Steel 316LSi is a 316L stainless steel welding wire with raised silicon, deposited by laser wire-feed directed energy deposition to build austenitic stainless parts to near-net shape.

Built bead by bead, it forms near-fully dense metal with columnar austenite grains along the build direction, some delta ferrite, directional anisotropy and a rough stepped surface that needs machining. The heat treatment relieves residual stress from repeated thermal cycling and reduces solidification segregation, though the columnar grains largely remain. Typical uses are near-net-shape parts, repairs and added features, and corrosion-resistant fluid-handling hardware, finish-machined after printing.

5.2Cr-1.7Mo-11.0Ni is a precipitation-hardening low-alloy steel designed to achieve very high strength through age-hardening heat treatment, combining chromium and molybdenum for hardenability with substantial nickel content for toughness and corrosion resistance. This material is primarily used in aerospace and defense applications where both extreme strength and damage tolerance are critical—particularly in landing gear, fasteners, and structural components that must survive high-cycle fatigue and occasional impact. The high nickel and chromium content also provides good corrosion resistance compared to conventional steels, making it suitable for environments with salt spray or chemical exposure, while the controlled molybdenum level ensures through-hardening without excessive brittleness.
This is a precipitation-hardening nickel-chromium-molybdenum low alloy steel, strengthened through martensitic transformation and age-hardening mechanisms. The high nickel content (11.4%) combined with chromium and molybdenum provides exceptional strength-to-weight ratio, corrosion resistance, and toughness at both ambient and cryogenic temperatures. Commonly used in aerospace landing gear, high-strength fasteners, and defense applications where demanding fatigue, impact, and environmental resistance are required; it competes favorably with maraging steels and titanium alloys in cost-sensitive applications requiring both ultra-high strength and damage tolerance.
5.6Cr-1.9Mo-9.8Ni is a low-alloy steel engineered for high-strength applications requiring good toughness and fatigue resistance, achieved through careful balance of chromium (corrosion and wear resistance), molybdenum (strength and hardness), and nickel (ductility and impact toughness). Primarily used in aerospace landing gear, high-performance automotive components, and heavy-duty machinery requiring both strength and damage tolerance. This composition is notable for maintaining reliable performance in cyclically loaded or shock-prone environments where brittle failure must be avoided, making it preferable to higher-carbon martensitic steels in applications where impact resistance and fatigue life are critical.
