StarBlaze Prime 410 NiMo
AWS A5.4: E410NiMo-15 | DIN EN ISO 3581-A: E 13 4 B 22 | Werkstoff Nr: 1.4351
Basic Coated | Martensitic | Corrosion & Pitting Resistant
StarBlaze Prime 410 NIMO is a basic coated electrode engineered for welding stainless martensitic chromium-nickel-molybdenum steels or cast equivalents such as AISI 410 NiMo. The deposit offers excellent resistance to abrasion, corrosion, and pitting. Being an air-hardening type, preheating and PWHT are necessary to achieve adequate ductility for machining and service life. Packed in vacuum sealed packaging for moisture protection.
excellent resistance to cracking, oxidation, and corrosion.
