GB/T 18248 34CrMo4

Posted:2018-08-13 11:00:30

34CrMo4 has high durability and creep strength at high temperature, good low temperature impact toughness, good hardenability, no tendency to overheat, small quenching deformation, good plasticity in cold edge shape, and medium workability. Poor weldability, preheating before welding, post-weld heat treatment and stress relief, generally used after quenching and tempering treatment, can also be used after high intermediate frequency surface quenching or quenching and low and medium temperature tempering.
