15Cr Martensitic Stainless (var. 8)

metal

15Cr Martensitic Stainless Steel (variant 8) is a high-carbon, cobalt-strengthened martensitic stainless steel designed for demanding applications requiring exceptional hardness and wear resistance combined with corrosion resistance. The elevated carbon content (~0.97%) and cobalt alloying (~13%) produce a material suitable for precision tooling, cutlery, and high-performance applications where both edge retention and corrosion resistance are critical; engineers select this grade over standard martensitic stainless steels or tool steels when the combination of hardness, toughness, and stainless properties cannot be compromised. The molybdenum and nickel additions provide additional hardenability and toughness, making this variant well-suited to components that experience cyclic loading or require fine dimensional tolerance after hardening.

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.
