Stainless Steel AL 17-4™ Precipitation

Postweld heat treating is needed to produce the vari-ous precipitation hardened heat treatment properties. If matching filler material is used, properties comparable to those of the parent metal can be produced in the weld by postweld precipitation hardening heat treatment. When a number of welding passes are made, a sub-

Inconel alloy 718 (Sept 07) Web - Special Metals Corporation

treatment as shown earlier is the optimum heat treatment for alloy 718 where a combination of rupture life, notch rupture life and rupture ductility is of greatest concern. The highest room-temperature tensile and yield strengths are also associated with this treatment. In addition, because of the fine grain developed, it produces the highest ...
