What is the application of q420d high strength steel?

Q420d steel is a low-alloy high-strength structural steel. Q420d is not only a high-strength steel, it is also a low-carbon steel. The tensile strength of q235 is 235MPa and the tensile strength of q420d is 420MPa. Due to the low carbon content of q420d, it cannot be processed by quenching and tempering, and it is still unable to process shafts and gears. q420d steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance.

q420d high strength steel application

q420d high strength steel has good mechanical properties and weldability, and good cold and hot workability. Due to the addition of Wei alloying elements, the strength and toughness of steel are improved and improved. q420d plate is mainly used to manufacture mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
