StarBlaze Prime 410 NiMo-16
AWS A5.4: E 410NiMo-16 | DIN EN ISO 3581-A: E 13 4 R 12 | Werkstoff Nr: 1.4351
Rutile Coated | Martensitic | Abrasion & Pitting Resistant
StarBlaze Prime 410NiMo-16 is a rutile basic coated MMA electrode formulated for welding martensitic stainless steels and cast steels containing Cr-Ni-Mo. It delivers a weld deposit with excellent corrosion, erosion, and pitting resistance, particularly in aggressive environments. Suitable for components subjected to high wear and thermal cycles, where ductility is restored through post-weld heat treatment.
