Eigenschaften
Preheating and interpass temperature 400-450 °C (austenitic welding) or 250-300 °C (martensitic welding). Root passes should principally be welded in the martensitic range. Lower preheat and interpass temperatures are possible, yet must be approved by practical welding tests and process qualification tests. After welding cooling to 90±10 °C, followed by tempering at 760 °C for three minutes / mm wall thickness at least for 2 hours. Tempering, if specified, at 1050 °C for 1/2 hour/oil and annealing at 760 °C for 2 hours.
