Product Details

Specifications

1,high-class bearing steel ASTM 4118H
3,good mechanical property and machinability
3,high strength and hardenability

ASTM 4118H/JIS SCM421/DIN (B22)20MnCr 4-2/GB G20CrMo

High hardenability, no temper brittleness, welding performance is quite good, the tendency to form cold crack is very small,

machinability and cold plastic strain of good. Generally used in the quenched and tempered or carburizing and quenching

condition, used to work in manufacturing non corrosive medium and the working temperature is lower than 250 DEG C,

containing a mixture of nitrogen and hydrogen in medium high pressure pipe and all kinds of fasteners, the higher the

carburizing parts, such as gears, shaft etc.
