WELDING ROD FONWELD HARD-FACING HF350 5.0MM

Product Description

WELDING ROD FONWELD HARD-FACING HF350 5.0MM (PRICE PER KG) is a chromium-alloyed hardfacing electrode with a rutile coating, designed for surfacing steel components exposed to metal-to-metal wear, impact, and mild abrasion. FONWELD HF350 produces smooth, even weld beads with good slag detachability and a tough weld deposit offering very good impact and metal-to-metal wear resistance. Heavy build-ups can also be applied without a buffer layer.
