Postalloy® 306-SPL

Postalloy® 306-SPL is a medium carbon, high strength solid 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 3/4" (19mm). When welding steels over 1/2" (12.7mm) a preheat of 300 °F (149 °C) is recommended. It is a versatile, easy to use welding wire with excellent operator appeal.
