ASTM A242 has 2 grades: Type 1 and Type 2, while type 1 is the most used structural steel grade. Usually S550 steel shot it is produced to be hot rolled state, it is suitable for cutting, forming, drilling and machining, grinding.

The difference between S550 steel shot, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.
