16Cr Martensitic Stainless (var. 11)
metalA high-carbon martensitic stainless steel (nominally 16% Cr) with significant cobalt and molybdenum additions, designed to achieve very high hardness and strength through martensitic transformation and precipitation hardening. This composition—particularly the elevated carbon (0.75%), cobalt (13%), and molybdenum (3%) content—targets extreme wear and corrosion resistance in demanding aerospace and industrial applications where conventional stainless steels fall short. The addition of aluminum and nitrogen further refines the microstructure, making this variant valuable for components that must endure both mechanical fatigue and corrosive environments simultaneously.

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.
