PRODUCTSWELDING CONSUMABLES
570~980MPa High Tensile Strength Steel Submerged Arc Welding Material NB-250H×Y-80M
Characteristics
NB-250H 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.
