- CREEP RESISTING STEELS
12CrMoV
Description
Rod for 12% Cr creep-resistant steels for high temperatures
This rod has been developed for welding steels designed for creep-resistant services, with particular effectiveness for extended applications at temperatures up to +550 °C. The deposit ensures high resistance to creep rupture and good toughness properties even under long-term stress. Preheating and interpass temperatures between 400 and 450 °C allow for an austenitic deposit, while working between 250 and 300 °C results in a martensitic structure. It is recommended to perform root passes mainly in the martensitic range.
