13Cr-2Ni Duplex Stainless (var. 2)

metal

A precipitation-hardened duplex stainless steel variant combining ~13% chromium with nickel, molybdenum, and notable additions of vanadium and cobalt to achieve a dual-phase ferrite-austenite microstructure with enhanced strength and hardness. This modified composition—particularly the elevated carbon, vanadium, and cobalt content—represents a research or proprietary variant optimized for demanding applications requiring both corrosion resistance and high strength, distinguishing it from conventional 13Cr duplex grades. Typical industrial use includes high-pressure oil & gas equipment, corrosive chemical environments, and applications where weight savings and fatigue performance are critical; the alloy family bridges the gap between commodity stainless steels and more expensive superalloys.

Quality & Standards

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
