GMAW-GTAW Solid wires
Precipitation hardening stainless steel filler metal used for welding materials of similar chemical composition such as 17-4 and 17-7.
To be used in the as welded condition or in the heat treated condition to obtain higher strength. Mechanical properties of this alloy are greatly influenced by the heat treatment.
Mechanical properties listed below reflect utilization of a post-weld heat treatment between 1020°C (1875°F) and 1050°C (1925°F) for one hour, followed by precipitation hardening between 612°C (1135°F)
