What is the Q355ME steel?

Q355ME steel belongs to low-alloy high-strength structural steel plate for structure and engineering.
Q355ME executive standard: GB/T1591-2018 "low alloy high strength structural steel".
 
Q355ME steel meaning
The name of the steel plate is composed of five parts: the initial letter Q of the Chinese pinyin representing the yield strength "yield", the prescribed value of the upper yield strength, the code of the delivery state, and the quality level (B, C, D, E, F).
Example: Q355ME. among them:
Q ———The initial letter of the Chinese Pinyin of "qu" for the yield strength of steel;
355—The specified small upper yield strength value, in megapascals (MPa);
M————The delivery status is thermomechanical rolling;
E-The quality level is E level.
Q355ME delivery status: thermomechanical rolling; steel plates should be delivered by shearing or flame cutting.
 
Application of Q355ME steel
Q355ME steel plate is widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment and other buildings.
