Developed for creep resistant, quenched and tempered 12 % Cr steels, such as X20CrMoV12-1, mainly used in in turbine and boiler
fabrication and in the chemical industry.
Approved in long-term condition up to +650 °C service temperature. The deposit exhibits high
creep rupture strength and good toughness properties under long term stresses. Preheating and interpass temperatures 400 – 450 °C (austenitic welding) or 250 – 300 °C (martensitic welding). Root passes should principally be welded in the martensitic range.Steel is mainly supplied in the form of hot-rolled boiler pipes, fittings and sleeves
