440C Stainless Steel Ball
440C Stainless Steel Balls – High Carbon Martensitic Grade, Superior Hardness & Corrosion Resistance
Our 440C Stainless Steel Balls are manufactured from high-carbon, high-chromium steel. Through precision machining and strict heat treatment processes, they achieve an excellent combination of high hardness (HRC 58-60), outstanding wear resistance, and good corrosion resistance. They are the ideal choice for applications demanding strength, durability, and moderate rust protection, widely used in precision bearings, medical instruments, cutlery, valves, and high-end industrial equipment.
