Q355ME steel is a low-alloy high-strength structural steel plate for structure and engineering.
Q355ME Standard: GB/T1591-2018 "Low Alloy High Strength Structural Steel"
What does Q355ME stand for?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). 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.
When the purchaser requires the Q355ME steel plate to have thickness direction performance, a symbol representing the thickness direction (Z direction) performance level shall be added after the above-mentioned grades, such as: Q355MEZ25.
Q355ME delivery status: thermomechanical rolling; Q355ME plates should be delivered by shearing or flame cutting.
Application
Q355ME steel plate is widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment and other buildings.
