A contemporary alternative to 4340 is Atlas 6582 through-hardening steel that has improved through-hardening characteristics andWelding heat treatable steels - The FABRICATORThe most commonly welded heat-treatable steels are 4130, 4340, and 8630. However, any steel prefaced with a 41, 43, or 86 is considered heat-treatable. When a weldment is heat-treated, it is put into a furnace at a predetermined temperature and cooling rate. The heat treatment produces a desired microstructure that changes the mechanical
