E81T1-Ni2 H4
AWS A5.36 E81T1-Ni2 H4
Description：
E81T1-Ni2 is designed for gas shielded flux cored welding of low alloy steels that require good CVN toughness at low temperatures. It is excellent for single and multiple pass, all positional welding with good operation properties like easy slag removal, stable arc, less smoke and spatter etc. Welding for 550MPa grade high strength structural steel, like vessels, machine manufacturing, petrochemical industries and structural bridges etc. Extra low hydrogen content 4ml/100g
