Product introduction
440C stainless steel balls are usually used in industries that require high precision and corrosion resistance, such as aviation, aerospace, bearings, motors, high-precision instruments, valves, and petroleum.
Features:
The metallographic structure belongs to martensitic steel, and the production process requirements are high. There are relatively few companies in China that can produce stainless steel 440C, so companies that can produce 440C materials are often known as special stainless steel. The heat treatment process is relatively complicated, easy to crack, and has high precision requirements. It is a harder stainless steel ball among steel balls, HRC>=58. The hardness is close to that of bearing steel balls, but it has stronger anti-rust and anti-corrosion properties than the former.
