BP300 bulletproof steel length Yield Strength

SAPH series steel plates for automobile structures have good stamping and forming properties, and are used to make automobile beams, wheels and other structural parts. Hot rolled high yield strength steel for cold forming has high strength and good cold formability, and is used to make structural parts such as automobile beams. BP300 bulletproof steel length, The steel for automobile girder has good stamping forming performance, and is used for manufacturing structural members such as longitudinal beams and transverse beams of automobile frames.

Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important BP300 bulletproof steel length heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the BP300 bulletproof steel length quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After BP300 bulletproof steel length quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of BP300 bulletproof steel length etc. steel material.
