CQ, DQ, DDQ, EDDQ, IF, HIF, HSS, Bake Hardening, High Strength, Micro Alloyed, C-Mn Difference Between Annealing and Tempering Metal May 09, 2016 · By annealing the metal beforehand, cold working can take place without any risk of cracking, as annealing releases mechanical stresses produced during machining or grinding. Annealing is used for steel, however, other metals including copper , aluminum and brass can be subject to a process called solution annealed. Hot-Rolled Steel vs. Cold-Rolled SteelMar 27, 2020 · However, once the treated steel is ready, cold-rolled steel goes through a few extra steps. The mill lets the metal cool off until it's room temperature, then draws it through rollers or puts it through annealing treatment. This additional labor makes it more expensive than hot-rolled steel. Visually Telling Them Apart
