13Cr Martensitic Stainless (var. 13)

metal

13Cr martensitic stainless steel is an iron-based alloy strengthened by chromium (13.4%) and hardened through martensitic transformation, with cobalt and molybdenum additions that enhance high-temperature strength and wear resistance. This variant appears optimized for demanding applications requiring superior hardness and strength retention, commonly found in aerospace turbine components, industrial cutting tools, and high-stress valve seats where corrosion resistance must be balanced with exceptional load-bearing capacity. Engineers select this alloy when standard martensitic grades cannot meet strength or temperature requirements, though it trades some toughness and formability for enhanced performance in extreme operating conditions.

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.
