Stress Relieving Steel and Annealing | Precision Grinding ...

Stress Relieving is a heat treating process that consists of heating the steel to a temperature below the critical range to relieve the residual stresses resulting from hot rolling, welding, shearing, or gas cutting. Unlike normalizing or annealing, stress relieving does not change the metal's chemical / mechanical properties. We recommend ...

Metallographic Abrasive Grinding

Thus, for larger hard specimens higher grinding/polishing pressures increase stock removal rates, however higher pressure also increases the amount of surface and subsurface damage. Note for SiC grinding papers, as the abrasive grains dull and cut rates decrease, increasing grinding pressures can extend the life of the SiC paper.

Warping Cold Rolled,

Jul 29, 2006· like JRouche said, use larger stock and skim cut all faces, or use hot rolled. the warpage occurs from the cold-rolling process, it compacts the surface of the material (I forget the depth, I seem to recall it's in the .005 or .01 range) but it's then under tension. the tension is equal on all 4 sides *until* you mill it- then it *springs* (not the exact correct term, I don't think) and ...

Stress Relief of nitrided gears and splines? - Gear ...

I agree with the comments from mfgenggear about thermal stress relief of gears and splined shafts prior to nitride. You would normally want as little post-nitride distortion in your gear or spline tooth surfaces as possible, since the thin nitride case does not allow for much stock removal in a finish grinding operation.
