Postalloy® 306-FCO
Postalloy® 306-FCO is a medium carbon, high strength flux-cored, open-arc wire designed for butt, fillet and lap welding of low carbon and low alloy steels. Recommended for single and multi-pass welding applications in all positions. Use on steel thicknesses from 16 gauge up to 1/2" (12.7mm) thick maximum. When welding steels between 3/8"-1/2" (10mm-12.7mm) a preheat of 325-375 °F (163-190 °C ) is recommended. It is a versatile, easy to use welding wire with excellent operator appeal. Without the need for shielding gas, Postalloy® 306-FCO is ideal for welding applications in which the addition of gas is impractical, or where windy and other adverse conditions prevail. It is not recommended for low temperature applications.
