Product Details

Mechanical properties: Yield strength (Rp0.2): ≥500 MPa
Tensile strength (Rm): usually between 550 and 690 MPa
Elongation after fracture (A): Depending on the thickness of the steel plate, the elongation has different requirements, for example, for a steel plate with a thickness of ≤40mm, A≥18%
Impact performance: The impact absorption energy requirement of Q500D steel plate at -20°C is usually ≥34 J, which indicates that it can maintain high impact toughness even under low temperature conditions.
Application areas: High-strength structural components such as bridges, high-rise buildings, heavy machinery such as excavators, cranes, etc., pressure vessels, boilers and pipelines, shipbuilding, automotive industry, such as automotive beams, beams, etc.
Production process: Q500D steel plates are usually produced by thermomechanical rolling (TMCP) process, which controls the rolling and cooling rates to obtain a fine grain structure, thereby improving the strength and toughness of the steel.
