Forgeability
During the forging process, the forging is first heated to approx. 1150°C. Forging takes place in a temperature range of 1150°C - 950°C. This is followed by air or water cooling.
Weldability
The material 1.4432 can be welded well with and without filler metal. Heat treatment after welding is not necessary. The resistance to intergranular corrosion is not affected by welding.
