    440C stainless steel ball



    Application:440C stainless steel balls are usually used for precision and rust resistance demanding industries,such as aviation, aerospace, bearings, motors, high-precision instruments, valves, oil.
    Features:Martensitic steel microstructure, high requirements for production process .Heat treatment process more complicated, easy to crack, and high precision requirement. 440C is the hardest ball in stainless steel balls, HRC ≧ 58. Hardness closes to bearing balls, but the former has better rust and corrosion characteristics.
