Welding Tips

No pre-heat required. Cool between passes (below 300°F). Filler metal
suggested but not required. Post weld anneal not required. If post-weld
annealing is accomplished, follow with a rapid water quench to prohibit reforming
of the intermetallic phase.

When using GTAW or PAW, consider the adding of nitrogen in the
shielding/purging gas to ensure optimum pitting resistance. Recommended
Fillers: LDX2101 from Avesta Welding or 2209.

Machining

Excellent machining characteristics when compared to type 304
or 316L stainless. Superior machinability to most Duplex grades
