40Cr steel belongs to alloy structural steel. sa573 grade 58 high strength structural steel, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.

Oxygen (O) is a harmful element in steel such as sa573 grade 58 high strength structural steel. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
