Application areas:
AISI 440C stainless steel ball is usually used in demanding industries: aviation, aerospace,
bearings, motors, high precision instruments, valves, oil, precision and anti-rust performance.
Features:
Microstructure of a martensitic steel, the production process requires high.The heat treatment process is more complicated, easy to crack, and the high accuracy requirements, is the most hard ball in a stainless steel ball: HRC ≧ 58. Hardness close to the bearing steel ball, but than the former has more rust and corrosion performance.
