Description

34cr2ni2mo structural steel is characterized by high strength, toughness, good hardenability and stability against overheating, but it has high white spot sensitivity and temper brittleness. The weldability is poor. It needs high temperature preheating before welding and stress relief after welding. It can be used after quenching and tempering. Generally, important parts with high strength and good plasticity are made, and important parts with special performance requirements are made after nitriding treatment, such as shafts, gears, fasteners, etc.

2.Mechanical Property

Tensile strength σ B (MPA): 933 ~ 1011
Conditional yield strength σ 0.2 (MPA): 832 ~ 899
Elongation δ 5 (%): 19-20
Reduction rate of area: 53-64%
Impact energy Akv (J): 117
Impact toughness value α Ku (J / cm2): 144-172
Hardness: 274-303hb
