    I guess my question is mainly, what would be the best tool to use in cutting Stainless Steel pipe/tubing for exhaust/turbo work? That of course would greatly minimize the burrs? In order to just basically cut, quickly clean, and weld? Thank you in advance for any help!!! Greatly Appreciated Regards, Cleaver

  15. All you need to know about the heat-affected zone

    Jun 28, 2016 · Another common effect is corrosion, derived from stainless steels sensitive nature. Intense heat causes the precipitation of chromium carbides around the grain boundaries. In these areas, chromium content drops below 10.5 percent, and steel loses its ability to form a passive film and relinquishes its ability to be stainless.
