E81T1-Ni1
AWS A5.29: E81T1-Ni1M-JH4
AWS A5.36 E81T1-M21A6-Ni1-H4,
Description：
E81T1-Ni1 is designed for gas-shielded flux cored welding of low alloy steels that require good toughness at low temperatures. This alloy 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 500MPa grade high strength structural steel, like vessels, machine manufacturing, petrochemical industries and structural bridges etc.
