13Cr Martensitic Stainless (var. 24)

metal

13Cr martensitic stainless steel (variant 24) is a high-carbon, cobalt-strengthened stainless alloy designed for demanding applications requiring excellent hardness and wear resistance. The elevated carbon content (~0.5%), combined with cobalt and molybdenum additions, enables this material to achieve superior strength through martensitic hardening while maintaining corrosion resistance typical of 13% chromium grades. This variant represents a specialized composition optimized for applications where conventional martensitic stainless steels require enhanced performance—often seen in tool steels, precision components, and corrosion-resistant wear-critical parts that balance toughness with resistance to abrasion and chemical attack.

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.
