Cold rolled sheet or hot rolled sheet for spiral steel pipe raw materials

Hot-rolled sheets, that is, hot-rolled steel-rolled steel sheets or steel strips, commonly known as hot plates, are usually also written as stencils, such as hot-rolled sheets, but all refer to the same hot-rolled sheet. Refers to a steel plate having a width greater than or equal to 600 mm, a thickness of 0.35-200 mm, and a steel strip having a thickness of 1.2-25 mm. The cold rolled sheet is obtained by rolling a hot rolled coil as a raw material at a recrystallization temperature at room temperature.


The difference between hot-rolled and cold- 
rolled steel : hot-rolled steel is divided into structural steel, low-carbon steel, and welded steel, and then you can find the steel you need according to various steels, and check the density and composition of specific steel. 
The hot-rolled steel sheet has low hardness, easy processing and good ductility. 
The cold rolled sheet has high hardness and high relative strength of processing.
