Description
Q355 is a kind of steel. It is a kind of low-alloy high-strength structural steel, widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment, etc., where "Q" means yield strength, 355 means that the yield strength of this steel is 355MPa, and will change with time. As the thickness of the material increases, its yield value decreases.
