Features & Applications
It is used for main parts of ships, e.g. boilers, pressure vessels and pipes made by equivalent
tensile strength steels, such as A, B, D, E, AH36, DH36 or EH36. Also it can be applied to
homothetic strength structures of bridges, machineries, constructions, vehicles and so on.
The weld metal has good performance of plasticity, impact toughness and crack resistance.
