What is "Cold Rolling" Stainless Steel and Other Metals?
How Does a Cold Rolling Mill Work? The process of cold rolling a metal alloy starts with either sheet metal or strip coil. These materials are placed into large rollers, which compress it down and squeeze it under high pressure just below its ultimate tensile strength. Depending on the amount of compression, different mechanical properties and ...
