Why should SA572 grade 60 carbon steel plate sheet be cut and heat treated

As a common steel plate in the steel market, SA572 grade 60 carbon steel plate sheet, manganese steel plate has the following characteristics. First, good toughness, stretching and crimping can be done well. Second, the bearing strength of manganese steel plate is good and it can bear a lot of gravity. Third, the SA572 grade 60 carbon steel plate sheet, manganese steel plate is easy to weld, easy to process finished products, and its price is relatively low. Fourth, manganese steel plate has good corrosion resistance, and long service life. Fifth, the manganese steel plate has good mechanical properties, low temperature performance, good plasticity and weldability.

Process analysis of SA572 grade 60 carbon steel plate sheet, Q960D quenched high strength plate: hot metal pretreatment → converter top bottom blowing → LF furnace → RH vacuum treatment → continuous casting → billet inspection → billet heating → high pressure water descaling → rough rolling → finishing rolling → ACC water cooling → straightening → cooling in cold bed → finishing → shot blasting → tempering treatment → performance inspection → finished product warehousing. LF, Si - Ca - Ba line and RH vacuum treatment were used to ensure the cleanliness of Q960D steel.

Quenching Improve the hardness of SA572 grade 60 carbon steel plate sheet steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of SA572 grade 60 carbon steel plate sheet steel and comprehensive mechanical properties.

Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
