S355JR carbon steel plate sheet standard specification

As people have higher and higher requirements for the quality of various steel processing products, the market demand for S355JR carbon steel plate sheet, pickling steel coils is getting better and better. At present, they are mainly concentrated in the automotive industry, compressor industry, machinery manufacturing industry, spare parts processing industry, fan Industry, motorcycle industry, steel furniture, hardware accessories, electric cabinet shelves and various shapes of stamping parts. With the advancement of technology, hot-rolled pickled steel plates are currently involved in home appliances, containers, electrical control cabinets and other industries.

The difference between S355JR carbon steel plate sheet, 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.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S355JR carbon steel plate sheet quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After S355JR carbon steel plate sheet quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
