The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of ASTM A514M/A514 Grade A cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.

At the same time can reduce the hardness, improve the ASTM A514M/A514 Grade A plasticity and toughness, improve the cutting performance.Therefore, annealing is not only to eliminate and improve the tissue defects and internal stress left by the previous process, but also to prepare for the subsequent process, so annealing belongs to the ASTM A514M/A514 Grade A heat treatment of semi-finished products, also known as pre-heat treatment.
