High Performance Gb 45crnimova Steel Material Standards And Classification - China

GB 45CrNiMoVA steel is a kind of alloy structural steel specified by China's national standard.

Its standard mainly stipulates the requirements of mechanical properties, delivery status and other aspects of this steel.

Mechanical properties: After proper heat treatment (such as quenching + tempering), its tensile strength (σb) is usually not less than 1470MPa, yield strength (σs) is not less than 1325MPa, elongation (δ5) is not less than 7%, section shrinkage (ψ) is not less than 35%, and impact absorption energy (Aku2) is not less than 31J.

These performance indicators ensure the reliability of the material under high load and high stress conditions.

Delivery status: It is usually delivered in annealing or high temperature tempering state.

At this time, the steel has moderate hardness and is convenient for subsequent mechanical processing, such as cutting and drilling.

Classification by use: GB 45CrNiMoVA steel belongs to quenched and tempered steel among alloy structural steels.

After quenching and high-temperature tempering (quenching and tempering treatment), this type of steel has good comprehensive mechanical properties, that is, a good combination of high strength and high toughness.

It is widely used in the manufacture of important parts that withstand large loads and impacts, such as turbine shafts in aircraft engines, key components of landing gear, and drive shafts and connecting rods in heavy machinery.
