1. Conformance:

GB/T10045-2018/ T553T1-1C1A-N2/AWS E81T1-Ni1C/AWSA5.36 E81T1-C1A2-Ni1

2. Characteristics:

It is Low Alloy Steel Flux Cored Wire with titanium oxide slag system and CO2 shielded flux cored wire, with excellent bead appearance, low spatter, good slag detachability, and outstanding anti-porosity performance.

 

3. Application：

Suitable for welding boiler pipes and heat exchangers with the welding work temperature below 510℃ and other occasions. Adding 0.5% Mo to this wire, this helps to improve the weld strength and corrosion resistance.
