Q690E material has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance. In addition, , Q690 high strength steel plate and sheet has good corrosion resistance and certain wear resistance High strength, especially in the normalizing or normalizing plus tempering state has a higher comprehensive mechanical properties,A588 grade B HSLA steel plate.
A588 grade B HSLA steel plate,Good weldabilityBecause of its low carbon content, low alloy element content, good plasticity and low hardenability, this material is not suitable to have quenching structure or crack at the weld. The cold and hot pressure processing performance is good. Because of its good plasticity and small deformation resistance, it is not easy to produce cracks after pressure processing. Good corrosion resistanceUnder various atmospheric conditions, it has higher corrosion resistance than carbon steel.A588 grade B HSLA steel plate
Tempering the important welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve strength, plasticity and toughness.
