15CrMnMoVA is a low carbon and low alloy bainite steel with secondary hardening phenomenon. After quenching and high temperature tempering, it has high strength, good plasticity and toughness, good stamping and welding properties. 15CrMnMoVA quenching and tempering treatment, can be welded any complex component, without heat treatment after welding, small hardenability. 15CrMnMoVA is suitable for manufacturing welding parts and plate and gold parts with small cross section, and can be used as pressure shell, etc.
