Analysis of A516 steel properties and performance

A516 steel belongs to ordinary carbon steel, and cracks will appear during the rolling process. A516 steel is prone to cold cracking in the steelmaking process, that is, when the slab is heated to a certain temperature and then cooled and then released from the furnace, the inside of the slab is loose.

A516 steel plate belongs to cold crack. In order to eliminate cold cracks, reduce crack defects, and improve rail strength, corrosion resistance and wear resistance, the following measures should be taken when manufacturing automobile sheets:
(1) Use good rolling passes to reduce the content of inclusions in or between plates.
(2) Adopt appropriate heat treatment process conditions and heat treatment system to eliminate cold cracks.
(3) Quenching and tempering treatment is carried out immediately after cold and hot working to improve the strength, hardness, corrosion resistance and wear resistance of the steel.
A516 steel can be made into billets with a thickness of 3~6 mm (width 600~900 mm) by cold rolling or hot rolling. A516 steel is used to manufacture steel plates and spring steel for trucks and other trucks. "Chinese standards stipulate the product quality control requirements for cold-rolled and hot-rolled sheets.
