13Cr Martensitic Stainless (var. 17)

metal

13Cr martensitic stainless steel (variant 17) is a chromium-hardened iron alloy with molybdenum and nickel additions, designed to achieve high strength through martensitic transformation and precipitation hardening. It is used in applications requiring a combination of corrosion resistance and superior mechanical strength, particularly in aerospace turbine components, power generation equipment, and oil & gas subsurface tools where both wear resistance and oxidation protection in demanding environments are critical. This variant's composition—including modest cobalt and vanadium content—positions it for high-temperature service and applications where traditional 13Cr stainless steels would be insufficient, making it an alternative to higher-nickel austenitic grades when weight savings or better corrosion-cracking performance is needed.

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.
