StarBlaze Prime 316
AWS A5.4: E316-16 | DIN EN ISO 3581-A: E 19 12 3 R 12 | DIN EN 1660: E 19 12 3 R 12 | Werkstoff Nr: 1.4430
Rutile Coated | Mo-Alloyed Austenitic | Corrosion and Heat Resistant
StarBlaze Prime 316 is a rutile-basic coated stainless steel electrode alloyed with Mo for enhanced corrosion resistance and mechanical strength. With approximately 5–8% ferrite in the deposit and coating designed for low moisture pickup (LMA Type), it offers clean slag removal, smooth arc characteristics, and excellent weld appearance. Suitable for welding and cladding of 316/316Ti stainless steels in tanks, pipelines, and pressure systems operating between -120°C and +400°C.
