SA573 Grade 70 raw material, Q460 material is a low-alloy high-strength steel. Q stands for the strength of steel. 460 means that plastic deformation occurs only when the strength of the steel reaches 460MPa. That is, when the external force is released,
SA573 Grade 70 raw material, Q460 material is a low-alloy high-strength steel. Q stands for the strength of steel. 460 means that plastic deformation occurs only when the strength of the steel reaches 460MPa. That is, when the external force is released, the steel can only maintain the shape of the force and cannot return to its original shape. This strength is greater than that of ordinary steel. Tensile strength is 550-720MPa, elongation: 17%, Q460 material is made by adding Cr, N, V, Ti and other alloying elements on the basis of 16Mn steel.
