E81T1-B2C Low Alloy Steel Flux Cored Wire


E81T1-B2C Low Alloy Steel Flux Cored Wire

The E81T1-B2C low alloy steel flux cored wire involves the utilization of Titanium slag system. Thisgas shielded welding wire is well-suited for 1%Cr-0.5%Mo heat resistant steel. Excellent weldability and stable arc can be achieved in all welding positions while offering low spatter, flawless bead appearance and superior slag detachability.

This kind of low alloy steel flux cored wire requires preheat process. The working temperature of this welding consumable is lower than 520℃ Therefore, our heat resistant steel flux cored wire is highly recommended for low alloy steel such as 15CrMo applicable for boiler, pressure vessel, oil tanker and oil refining equipment, etc.
