The delamination problem of S890QL steel equivalent

Cold rolled steel sheet has high strength, high hardness and high surface finish. It is generally thin steel plate and can be used as stamping steel plate. The strength of S890QL steel equivalent, hot rolled steel plate is relatively low, the surface quality can not match with that of cold rolled steel sheet. But its plasticity is good, and it is generally medium thick steel plate. The price difference between cold rolled steel sheet and hot rolled steel plate has a certain relationship with manufacturers. The quality of steel plate manufactured by different manufacturers is different, and the price is also biased.

S890QL steel equivalent, 30CrMnSiA steel has good machinability, small processing deformation and good fatigue resistance. If 30CrMnSiA steel is used to make a tool, it is processed to the tool shape by rough machining. Mill the cutting edge with a cemented carbide milling cutter and polish it with a polishing machine. There should be no problem for the surface roughness reaching 3.2. 30CrMnSiA steel has high strength, sufficient toughness and good hardenability after quenching and tempering. After quenching and tempering, 30CrMnSiA steel can be used for grinding wheel shafts, gears and sprockets.

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of S890QL steel equivalent. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.
