440C Stainless Steel Balls

440C Stainless Steel Balls

  • Applications: 440C stainless steel balls are usually used for precision and corrosion performance are demanding industries: aviation, aerospace, bearings, motors, high precision instruments, valves, oil.
  • Features: microstructure is martensitic steel, the production process are higher, domestic enterprises can produce less stainless steel 440C, 440C material it can produce is often labeled a special stainless steel business reputation. Heat treatment process more complicated, easy to crack, with high precision, is the most hard a steel ball stainless steel ball: HRC ≧ 58. Hardness close to the bearing balls, but stronger than the former anti-rust, anti-corrosion properties.
  • Comparison: more than 440 stainless steel ball with the rust, corrosion resistance, hardness and enhanced wear resistance is also increased.
