high tensile steel Product Introduction
Q500ME is a low-alloy high-strength structural steel plate for engineering use. Implement national standard: GB/T1591-2018.
The 'Q' at the beginning of the grade indicates yield, '500' means the yield value of the steel plate is not less than 500Mpa, 'M' means the rolling process of the steel plate is thermomechanical rolling, and the 'E' at the end means The steel plate grade is -40° impact.
Q500ME has high strength, good toughness and weldability. Due to its good comprehensive performance, it is widely used in the manufacturing of various engineering machinery structural parts.
