Hot Rolled vs Cold Rolled Steel: What's the Difference?
In fact, unlike hot rolling, cold rolling can only occur when a metal is below its re-crystallization temperature. Instead of heat, cold rolling replies on sheer mechanical stress to change the structure of stainless steel. The cold rolling process begins with either a sheet or a strip coil of stainless steel, or whatever metal is to be rolled.
