High Tensile Steel
NK-7018
CLASSIFICATION
AWS A5.1 E7018 | JIS Z 3212 D5016
PRODUCT DESCRIPTION
NK-7018 is an iron powder low hydrogen type electrode, which has been designed for the use on heavy-duty structures in all positions. Its hydrogen content of weld metal is very low and it has excellent toughness and crack resistibility. It has applied of low carbon steel with high efficiency high.
APPLICATIONS AND MATERIALS TO BE WELDED
Heavy-duty structures, shipbuilding, boilers, storage tanks, pressure vessels and thick plate structures using 50 kgf/mm2 class high tensile steel.
