EN10083-3 34CrMo4 steel work/ steel structures/ steel machining parts

Compared with 40Cr steel, 34CrMo4 steel has higher harden-ability. 34CrMo4 steel has high creep strength in high temperature, and it can work in 500℃ temperature. Its plasticity is ordinary in cold deformation, and its weld-ability is not very well.
