J506NiCrCu
Description:
J506NiCu is a low hydrogen potassium type weathering steel electrode. AC and DC dual-use, can be all-position welding. The deposited metal has excellent resistance to atmospheric corrosion, crack resistance and good ductility and toughness.
use:
For carbon steel and 490N / mm 2 Welding Tensile strength level weathering steel, such as rolling stock welded structure, offshore engineering, bridges and the like.
