Description
Rod for welding 1% Ni steels
Solid rod designed for welding low-alloy steels with 1% Ni and fine-grain steels also used for low-temperature applications. Suitable for the construction of offshore platforms, pressure vessels and pipelines, as well as for welding high-strength steel structures where PWHT is impractical, yet toughness and fracture resistance are still required.
