DIN EN 8555: E6-UM-60P
57–61 HRc | Impact & Abrasion Shield | Crusher-Grade Toughness
An extreme-duty hardfacing electrode engineered for abrasion-prone, high-impact surfaces. With a Cr-V-Mo enriched alloy matrix, STARBLAZE HF 550 forms an ultra-hard weld deposit resistant to cutting wear, grain erosion, and hammering. Ideal for crusher jaws, mixer blades, dredger components, and everything in-between. Designed for rebuilds that demand hardness—and hold it.
