AISI 4130 Steel - 25CrMo4 - JIS SCM430 - GB 30CrMo

If the temperature is 300-350 on the heat treatment processing, get the flake is a tendency. It is medium-Carbon alloy steel which can be oil quenched to attain a maximum as-quenched hardness of approximately 48HRC. Its hardenability is significantly higher than that of the carbon-molybdenum(40xx) grades. 4130 Alloy Steel Applications

Alloy Tool Steel Applications and Properties - Songshun Steel

Alloy Tool Steel for Sale. Different alloy tool steel grade has own identity, that means they play a different role in the industry and life. If you need to buy alloy tool steel, please make sure what steel grade is your need in the perfect way, according to the requirements of hardness, toughness, strength, specification and more. Aluminum and Aluminum Alloys - Materials Data property development. Many alloys respond to thermal treatment based on phase solubilities. These treatments include solution heat treatment, quenching, and precipitation, or age, hardening. For either casting or wrought alloys, such alloys are described as heat treatable. A large number of other wrought compositions rely instead on work
