14Cr Martensitic Stainless (var. 3)

metal

14Cr Martensitic Stainless Steel (variant 3) is a high-carbon, cobalt-strengthened martensitic stainless steel designed for applications requiring exceptional hardness and wear resistance combined with corrosion resistance. This composition—with ~19% cobalt, elevated carbon (~0.88%), and molybdenum additions—targets high-performance cutting tools, precision measuring instruments, and specialized aerospace/defense components where both hardness and modest corrosion resistance are critical. The cobalt and carbon content distinguish this from standard 13–14% Cr stainless grades, positioning it as a premium tool steel rather than a general-purpose stainless, chosen when conventional martensitic stainless or tool steels cannot meet simultaneous demands for wear life and corrosion performance.

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.
