“Q” represents the yield strength; “345” represents the yield strength value in MPa; “E” indicates grade (through -40 degree impact test). Q345EZ35 Plate is mainly used in construction machinery, mining machinery, metallurgical e

GB/T 1591 Q345EZ35 belongs to the low alloy and high strength steel plate. Q345EZ35 plate has low temperature impact property. The grade of the steel is composed of three parts: the Chinese phonetic alphabet, the yield strength value and the quality grade symbol which represent the yield strength. “Q” represents the yield strength; “345” represents the yield strength value in MPa; “E” indicates grade (through -40 degree impact test). Q345EZ35 Plate is mainly used in construction machinery, mining machinery, metallurgical environmental protection, water conservancy and hydropower, track equipment and other structural parts.
