Hi-Alloy HFW 354 0.045″ x 25 lb. Spool * Metal cored manganese fluxcored alloy * May be used with or without a shielding gas * Hardness 15 – 20 RC as welded * Work hardens to 50 – 55 RC

Hi-Alloy gas-shielded flux cored wire delivers high deposition rates and excellent weld quality for single and multi-pass welding. This wire features smooth arc characteristics, complete slag coverage, and easy slag removal. Designed for use with CO₂ or mixed gas shielding, it provides excellent weld joint penetration and virtually eliminates fusion defects. All-position capability makes it ideal for structural steel, shipbuilding, heavy equipment, and pressure vessel fabrication where productivity and quality are critical.
