Medium carbon nickel-chromium-molybdenum alloy steel with good strength, toughness and fatigue resistance. Used for crankshafts, high-strength bolts and heavily loaded automotive components.
Applications
Nickel-chromium-molybdenum case-hardening (carburizing) steel, higher carbon variant than SNCM220; gears, shafts, and highly stressed transmission components requiring wear-resistant carburized surface and tough core
