EN 34CrNiMo6 Steel is an important alloy engineering steel grade as per BS EN 10083-3:2006. 34CrNim06 steel has high strength, high toughness and good hardenability. EN / DIN 34CrNiMo6 alloy steel has the stability of resistance to overheating, but the white sensitivity of 34CrNiM06 is high. It also has the temper brittleness, so the weldability of 34CrNiMo6 material is poor. The steel 34CrNiMo6 needs the high temperature preheating before welding in order to eliminate the stress after welding processing.
