Duplex Stainless Steels Welding Guidelines

If forming is finished above 950°C (1740°F) and cooling is fast enough (activated air or water) the final heat treatment can be avoided. When hot forming is applied to welds with 2209 or 2304 filler materials, a new heat treatment at 1050°C (1920°F) followed by rapid cooling (active air or water) is required.
