StarBlaze MIG Wire ER385

StarBlaze MIG 385 is a premium, precision layer-wound solid super-austenitic stainless steel MIG welding wire. Classified under AWS A5.9 as ER385, it deposits a highly alloyed 20% Cr / 25% Ni / 5% Mo / 1.5% Cu weld metal profile specifically formulated for maximum resistance against heavy acids and localized pitting.

Core Product Features
“StarBlaze MIG 385 is used for welding of ASTM 316 or similar steels, when a ferrite-free weld metal is required. Mainly used in cryogenic and nonmagnetic applications. The impact strength at low temperatures is excellent.”
Severe Acid Defense: The high nickel, molybdenum, and copper alloy additions provide elite protection against aggressive non-oxidizing acids, specifically hot sulfuric and phosphoric acids.
Ferrite-Free Performance: Deposits a fully austenitic microstructure free of delta ferrite, ensuring non-magnetic properties and unmatched fracture toughness at sub-zero temperatures.
Localized Corrosion Immunity: Delivers high resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking (SCC).
Ultrasonic Surface Cleaning: The wire undergoes intensive chemical bathing and ultrasonic cleansing to eliminate surface contamination, resulting in an exceptionally stable, low-spatter arc.
