Q355 steel is a low-alloy high-strength structural steel(HSLA), which replace Q345. The implementation standard of Q355NE is GB/T1591-2018. Grade Q355NE is -40 degrees impact. "Q" means yield strength, 355 indicates the yield strength is 355MPa, N is normalized or normalized rolling, and E is the quality grade. There are five quality grades under Q355N like B, C, D, E, F.

Application of Q355NE HSLA steelQ355NE low alloy steel has good comprehensive mechanical properties, low temperature performance, good plasticity and weldability. It is used as medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads, mechanical parts, and buildings. Structure, general metal structural parts, used in hot rolled or normalized state, Q355NE plates can be used for various structures in cold regions above -40, Q355NE is widely used in engineering, mining machinery, bridges, vehicles, ships, construction, pressure vessels, special equipment Wait.
Q355NE steel plates delivery status: normalized or normalized rolling
The Q355 steel is delivered in the state of hot rolling, normalizing, normalizing rolling or thermomechanical rolling (TMCP).
