Steel Grade 34CrNiMo6+A+QT+SR / 1.6582 /SAE 4340 400mm Forged Steel Round Bar OD 380 430MM
1: 34CrNiMo6 steel introduction
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.

4: 34CrNiMo6 steel mechanical properties
The mechanical properties mainly include tensile strength, yield
strength, elongation, area or reduction, hardness, impact value,
non-metalic inclusion etc. Different heat treatment, the mechanical
properties will be different, such as normalized, tempered, QT. If
you want to know the properties, kindly contact the salesman.
