AISI 8630 Alloy Steel Bars consist of carbon (0.28–0.33%), manganese (0.40–0.70%), nickel (0.40–0.70%), and molybdenum (0.15–0.30%), providing a good balance of hardness, strength, and toughness. This alloy exhibits tensile strength of 850–1000 MPa, good ductility, hardenability, and impact strength. It is also resistant to fatigue loading, particularly following heat treatment operations such as quenching and tempering. The steel‘s weldability and machinability are good, hence its great versatility, making it suitable for use in a wide range of precision-machined parts across critical industries.
