E81T1-K2
AWS A5.29 : E81T1-K2C/M
AWS A5.36 : E81T1-C1/M21A4-K2
Description：
E81T1-K2 is designed to produce weld metal with increase strength (without being air hardenable) & with increase notch toughness at low temperature. This Nickel steel weld metal can be used without PWHT.Often used in structural applications where excellent toughness is required. Welding for 620MPa grade high strength structural steel, like vessels, machine manufacturing, petrochemical industries and structural bridges etc.
