570~980MPa High Tensile Strength Steel Submerged Arc Welding Material NB-80×Y-80

Characteristics

NB-80 is a bonded flux designed to minimize the diffusible hydrogen content in weld metal and, therefore, crack resistance is extremely high. Impact properties are excellent at low temperature and slag is easy to remove even in narrow grooves.

Applications

Welding of 780MPa high tensile strength steel for offshore structures, pressure vessels, penstocks and bridges. Welding of 3Ni-1.75%Cr-0.5%Mo steel such as ASTM A508 Gr.4N and A543 type B Cl.1 steel.
