WebThis process is very precise in applying heat selectively to the areas that need to be heat-treated. Further, this process can be run at high speeds, produces very little distortion. Electron Beam Hardening: Electron Beam Hardening is similar to laser beam hardening. The heat source is a beam of high-energy electrons. WebInduction Hardening is a heat treatment performed to harden the surface of the steel containing carbon more than 0.35%, such as S45C or SCM440. For gear products, induction hardening is effective to harden tooth areas including tooth surface and the tip, however, the root may not be hardened in some cases. The precision of gears declines …
