CHEM-WELD 7020 MIG welding wire with higher strength, crack resistant

CHEM-WELD 7020 M

Crack-resistant welding wire

Standard:

AWS A 5.28: ER 100 S-G

Protective gas:

M21: Ar +_CO2 (18-20%), optionally M22-M33 (Ar + _O2)

Multi-purpose wire electrode. Excellent mechanical values at low temperatures. Welding metal can be cut with a cutting torch. Extremely high tensile strength. Copper plating for optimum corrosion protection.For low alloy steels (S (P) 460; S (P) 620), structural steel, for repairs on earth moving machines, cranes, excavator buckets, excavator teeth, boom arms, etc. For welding of non-alloyed and low-alloyed, fine-grained, structural steels, high-strength, annealed steels or low-temperature tough steels. The weld metal is tough and crack resistant.Materials: N-A-XTRA 55-70, T1-T19 Hy80, Hy90, Hy100 and STE 550-690 fine grain steels.
