14Cr Martensitic Stainless (var. 9)

A high-carbon martensitic stainless steel with ~13.5% chromium, ~1.15% molybdenum, and elevated carbon content (~0.88%), designed for applications requiring both corrosion resistance and very high strength. This alloy combines the hardening capability of martensitic stainless steels with molybdenum additions for improved wear and corrosion resistance, making it suitable for demanding environments where both mechanical performance and oxidation resistance are critical. Compared to standard 13% chromium martensitic grades, the higher carbon and molybdenum content raises hardness and fatigue resistance at the trade-off of reduced toughness, directing it toward precision components rather than general-purpose cutlery or structural applications.
