Product Description

Q420 hsla steel plate is a kind of low alloy high strength structural steel, the implementation standard is GB1591-2008. Q420 hsla steel sheet is divided into 5 quality grades: Q420A hsla structural steel, Q420B Low Alloy Steel Plate, Q420C low alloy structural steel, Q420D low alloy steel sheet and Q420E high strength steel plate.

Q420 high strength low Alloy Steel Plate has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion resistance and certain wear resistance. It has high strength, especially in the normalizing or normalizing and tempering state, and has high comprehensive mechanical properties.

Q420 high strength low alloy steel sheet is suitable for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, overweight machinery, mining machinery, and other large welded structural parts.
