By certification [File Integrity]
440C stainless steel ball is martensite type steel, the production process requirements are very high, China production of stainless steel 440C material enterprises are often known as special stainless steel reputation. 440C stainless steel ball heat treatment process is more complex, easy to crack, and high precision requirements, is the hardest stainless steel ball.
440C stainless steel balls, c ≥ 1%, most high-temperature processing oil quenching, so the microstructure change, hardness increase sharply, from less than HRC20 before quenching can achieve HRC58 above, so as to improve the wear resistance of steel ball, the ball will improve hardness, thus in the process of grinding, processing speed is more slow, suitable for higher precision, better products, so 440C stainless steel balls are widely used for bearings, motor, valve, locks, because the markov shape steel carbon content is higher, so will be showed by the magnet to absorb, so if you want to product does not rust, Also magnetic, 440C stainless steel balls are the best choice. 440C stainless steel balls are usually used in industries that require high precision and antirust performance: aerospace, aerospace, bearings, motors, high precision instruments, valves, petroleum.
