Q690 hsla steel is a kind of low alloy high strength structural steel. Q690 low alloy steel material is named after the yield strength value, where "Q" represents the yield strength, and "690" means that the yield strength of the steel is 690 MPa . Q690 high strength low alloy steel not only has high strength, but also belongs to the category of low carbon steel.
Q690 high strength steel materials are divided into different quality grades, including Q690C high tensile steel, Q690D high strength alloy steel and Q690E high strength low alloy structural steel.
Steel plates made of Q690 hsla steel plate material are widely used in coal mining machinery, engineering machinery, heavy-duty vehicles, bridges and pressure vessel plates due to their high yield strength and tensile strength.
