16Cr Martensitic Stainless (var. 18)

metal

A high-carbon martensitic stainless steel (≈16% Cr) strengthened by significant vanadium, molybdenum, and cobalt additions, designed for applications demanding both corrosion resistance and extreme hardness. This composition—with nearly 1% carbon and substantial interstitial strengtheners—represents a premium tool steel variant positioned between conventional martensitic stainless steels and cobalt-hardened high-speed steels, offering superior wear resistance and edge retention compared to lower-carbon martensitic grades. Industrial adoption focuses on precision cutting tools, gauges, and wear-critical components in aerospace and manufacturing where corrosion resistance cannot be sacrificed for performance.

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.
