E81T5-B2C Low Alloy Steel Flux Cored Wire

The E81T5-B2C low alloy steel flux cored wire is formulated with basic type slag system. This gas shielded wire is born with outstanding weldability and mechanical properties. Our low alloy steel welding equipment delivers reliable arc, negligible spatter and prime finish.

200-300℃ preheat is required by this low alloy steel flux cored wire. This welding consumable is greatly applicable for 1.0%Cr-0.5%Mo low alloy steel structures below 520℃.
