14Cr Martensitic Stainless (var. 10)

metal

14Cr Martensitic Stainless Steel (variant 10) is a precipitation-hardening martensitic stainless steel alloyed with cobalt and molybdenum for enhanced strength and wear resistance. This alloy is engineered for demanding applications requiring high hardness and corrosion resistance in moderately corrosive environments, commonly found in aerospace components, precision tooling, and high-performance mechanical systems where the combination of stainless properties and hardness is critical. The cobalt addition (12 wt%) distinguishes this variant, boosting strength and thermal stability compared to conventional 13% chromium martensitic grades, making it suitable for elevated-temperature service and applications demanding superior fatigue 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.
