High Temperature Properties

Condition: solution annealed

Welding
Good weldability. Welding is possible with all processes usual for stainless steels. We recommend depending on applications electric arc welding with covered electrodes, inert gas welding or SA-welding. Preheating and heat treatment after welding is not necessary. For high stressed heavy walled constructions the limited preheat temperature of 150°C maximum is recommendable. Maximum interpass temperature 150°C. Keep heat input low especially for small wall thicknesses. The TIG-process should be given reference for root welding.
