OEM Q355B Mild Hot Rolled Steel Metal Materials
Q355B Mild high strength low alloy metal
It can be used as the structure, mechanical parts, building structure and general metal structure of medium and low pressure containers, oil tanks, bridges and other structures that bear dynamic loads.
Q355 is a kind of low alloy high strength structural steel, widely used in Bridges, Vehicles, Ships,Construction, Pressure Vessels, Special Equipment, etc. "Q" means yield strength, 355 means that the yield strength of this steel is 355MPa, and the yield value will decrease as the thickness of the material increases.
