Key features
- Used for 3%, 5% and 9% nickel steels to give good strength and toughness in LPG and LNG processing or storage plant. In sulphurous atmosphere the weld metal can be used <500°C
- Used for joining ferritic to austenitic steels (dissimilar) with operating temperatures or postweld heat treatment higher than 300°C.
- Even at higher temperatures there is only limited carbon diffusion in the weld metal thus avoiding crack-prone carbide commissures in the weld interface of dissimilar joints.
