Standard:
EN ISO 17632- A:T 46 6 2Ni P M1 1
AWS A5.20 E81T1-Ni2
GB/T 17493 E551T1-Ni2M
Description: E81T1-Ni2 is also designed for gas shielded flux cored welding of low alloy steels that require good CVN toughness at low temperatures. It is excellent for single-pass and multi-passes, all positional welding with good operation properties like easy slag removal, stable arc, less smoke and spatter etc.
Application: Welding for 550MPa grade high strength structural steel, like vessels, machine manu facturing, petrochemical industries and structural bridges etc.
