ASTM A276 440C stainless steel round bar is a high-hardness, high-carbon martensitic stainless steel bar with 16.0-18.0% chromium, 0.95-1.20% carbon, 1.0% maximum manganese, and 1.0% maximum silicon, featuring a minimum hardness of 56HRC (heat treated) and exceptional wear resistance, designed for demanding applications in bearings, valves, and high-precision cutting tools where extreme strength, corrosion resistance, and dimensional stability are critical.
GNEE Stainless Steel is a renowned stockist and distributor of SS 440C bar stock. Our ASME SA276 440C stainless steel round bar, toughened and stress-relieved, combines full rigidity with corrosion resistance and high strength. Suitable for needle valves, cutlery, ball check valves, pump components, valve seats, bushings, wear-resistant textile parts, and ball studs. 440C bar stock is generally not recommended for high-temperature applications, as its corrosion resistance decreases when hardened above 400°C.
