Stainless Steel Coil 316 (HR CR HL Surface)

Cold rolled stainless steel is processed and rolled on the basis of hot rolled Stainless Steel Plate roll, generally speaking, hot rolling → pickling → cold rolling such a process. Although in the process because of rolling will also make the steel plate temperature, in spite of this is still called cold rolling. As a result of hot rolling through continuous cold deformation of cold rolling, the mechanical properties are relatively poor, the hardness is too high. Must be annealed to restore its mechanical properties, not annealed called rolled hard roll.Cold Rolled Coil is Hot Rolled Coil as raw material, is the recrystallization rolling, but generally understood as the use of normal temperature rolling material rolling. Hot rolled coil is made of slab (mainly continuous casting billet) as raw material, which is heated and made into strip by roughing mill and finishing mill.
