vs. "stress relieving" ?''s - Practical Machinist - Largest Manufacturing
28 May 2008 I do a lot of plate work out of 1045 hot roll steel and typically have the plate " stress relieved" after being burned out and prior to grinding. Stress relieving might mean raising it to the same temperature but is often done to a 1045 steel be annealed or stress relieved so that the steel is easier to machine.
