Description:
Stainless steel ball 440 / 440C: Performance: hardness of 56-58 degrees, magnetic, corrosion resistance, high wear resistance and toughness
Uses: mainly used in bearings, stamping / hydraulic fittings, valves, seals refrigeration equipment, aerospace and high precision mechanical parts, handicrafts, toys.
Specifications: 0.5mm-100mm
Applications: 440C stainless steel balls are usually used for precision and rust resistance are demanding industries: aviation, aerospace, bearings, motors, high-precision instruments, valves, oil.
Features: microstructure is martensitic steel, high production process requirements, less domestic enterprises can produce stainless steel 440C, 440C are able to produce materials companies often dubbed special stainless steel in the world. Heat treatment process more complicated, easy to crack, and high precision, is a ball the hardest steel ball: HRC -58. Hardness approaching ball bearings, but the former has a stronger anti-rust, corrosion resistance.

Compare:stronger than the 440stainless steel ball rust, corrosion resistance, hardness enhanced wear resistance increases.


We offer a variety of ball bearings and bearing, and look forward to your order. . .
