High Hardness | Abrasion Resistant | All-Position Martensitic Overlay
StarBlaze HF 650B (SPL) is a high-alloyed, basic coated hardfacing electrode formulated to deliver a tough, non-machinable martensitic weld deposit. It offers superior resistance to abrasion and moderate impact, especially under metal-to-mineral wear conditions. With excellent slag removal, low spatter, and all-position usability, it is ideal for extending service life of heavy-duty industrial components.
