EN S420M steel plate heavy plate 10cm thikness spot

EN S420M steel plate, Large diameter spiral steel pipe refers to the relatively large diameter spiral steel pipe, which is generally required to be more than 1000mm. The manufacturing process of large-diameter spiral steel pipe: first, the steel strip is bent into shape, and then welded together to make a large-diameter spiral steel pipe of specified size. After being processed into a pipe, hydrostatic test, bending, flattening and other tests shall be carried out, and the internal steel support of large-diameter spiral steel pipe can be made according to customer requirements.

BS600MCJ4 steel is a hot rolling carbon low-alloy high strength steel. It is design by reducing the carbon equivalent of the steel and welding crack sensitivity index, and use of advanced smelting equipment and technology to strengthen the collection of micro-alloying technology, good weldability. We sincerely hope to establish long-term cooperation relationship with you on the basis of mutual benefit, reciprocity and common development for EN S420M steel plate project.

Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between EN S420M steel plate, hot rolled sheet and cold rolled sheet?
