Product Description

EN10297-1 34CRMO4 GAS CYLINDER TUBE

34CrMo4 is an alloy structural steel with high endurance and creep strength at high temperatures. It's mainly used for cylinder manufacturing or structural parts working under high loads such as transmission parts of vehicles and engines; turbine-generator rotor, spindle, heavy load drive shaft, large section parts, locomotive traction gear, supercharger transmission gear, rear shaft, connecting rod and spring clamp with great load, can also be used for the oil drilling pipe joints and fishing tools below 2000m. However, its poor weldability requires preheating before welding, heat treatment after welding and stress elimination. It is generally used after quenching and tempering, and used after high and medium frequency surface quenching or quenching and low and medium temperature tempering.
