Surface hardness achievable is 600 to 650HV. Induction or Flame Hardening Atlas 4140 can be surface hardened to 58HRC (typical value). Welding
Stainless Steel AL 17-4™ Precipitation
www.specialtysteelsupply.comIn the case of welding with non-matching filler, an aus-tenitic stainless steel such as 308L or other ductile aus-tenitic should be used. This filler will not produce the precipitation hardening response, however. HEAT TREATMENT The AL 17-4 Precipitation Hardening Alloy is furnished in the annealed condition. This is also called the solu-

Work Hardening and Annealing of Copper - Materials …
materialseducation.orghardening the metal by deformation. If an appropriate furnace is available, it also demonstrates the softening process of annealing. Copper wire or tubing is quite soft in its initial state, allowing for a variety of uses where the tubing needs to be bent to a desired shape. Upon bending, the copper hardens due to work hardening (also called strain
