WELDING ROD FONWELD HARD-FACING HF350 4.0MM

Product Description

WELDING ROD FONWELD HARD-FACING HF350 4.0MM (PRICE PER KG) is a chromium-alloyed hardfacing electrode with a rutile coating, designed for restoring and protecting 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 deposit offering very good impact and metal-to-metal wear resistance. The deposit is also machinable, making it suitable for repair and dimensional build-up applications.
