Domestic Market

316 / 316HStainless Steel Filler Wire

316 / 316H welding wire is designed for welding austenitic stainless steels that operate at high temperatures under long-term creep conditions. This product is widely used for welding 316 and 316H stainless steel grades in applications where strength, ductility, and resistance to thermal embrittlement are important. The modified weld metal composition helps reduce the risk of cracking in thick and highly restrained weldments, making it suitable for critical high-temperature structural service.

Properties

Superon 316 and 316H welding consumables are widely used in chemical, petrochemical, marine, and industrial fabrication, where exposure to corrosive environments and elevated temperatures is common.

Austenitic Stainless Steel Weld Metal: Provides stable, crack-resistant welds with excellent toughness and ductility, suitable for both fabrication and repair
Enhanced Corrosion Resistance: Contains molybdenum, improving resistance to pitting, crevice corrosion, and general attack in chloride-rich and acidic environments.
High-Temperature Performance (316H): 316H is specially formulated with higher carbon content to maintain strength at elevated service temperatures without compromising corrosion resistance.
Good Mechanical Strength: Offers high tensile and yield strength with balanced ductility, ensuring welded joints can withstand stress, vibration, and thermal expansion.
Smooth and Uniform Weld Beads: Produces clean, attractive welds with excellent wetting and minimal spatter, reducing post-weld finishing.
Stable Arc Performance: Delivers reliable welding with consistent metal transfer in MIG, TIG, and stick processes.
Versatile Applications: Ideal for chemical processing equipment, storage tanks, piping systems, marine structures, and industrial fabrication exposed to harsh or high-temperature environments.
