ER316/316H MIG & TIG Welding Wire

ER316/316H MIG & TIG Welding Wire welding wire, offered by Metals And Welding Specialities, is a premium-grade stainless steel filler metal designed for superior corrosion resistance, high-temperature performance, and excellent weld integrity. Manufactured to meet AWS A5.9 ER316/316H specifications, this alloy combines strength and stability for both MIG (GMAW) and TIG (GTAW) welding applications. The product adheres to UNS S31603/S31609 and corresponds to ASTM A240 Type 316/316H standards, ensuring top-quality consistency and compatibility across industrial welding operations.

With a balanced chemical composition of chromium, nickel, and molybdenum, ER316/316H wire provides outstanding resistance to pitting, crevice corrosion, and intergranular attack in chloride-rich and acidic environments. Its low carbon content in ER316 and stabilized high-carbon version ER316H make it suitable for both cryogenic and elevated temperature conditions. This filler wire delivers smooth arc stability, minimal spatter, and clean weld beads, making it a trusted choice for fabricators working on chemical processing equipment, pressure vessels, heat exchangers, and food-grade piping systems.

The AWS ER316/316H alloy is specifically engineered for joining stainless steels of similar composition, such as 316, 316L, 316H, and their cast equivalents. It maintains high tensile and creep strength even under prolonged thermal exposure, offering extended service life in high-stress environments. Its superior slag detachability and consistent wire feed performance make it suitable for automated and semi-automatic welding operations. The inclusion of molybdenum enhances corrosion resistance against seawater and acidic media, while the higher carbon content in ER316H provides added strength retention at elevated temperatures.

At Metals And Welding Specialities, every spool and batch of ER316/316H MIG & TIG wire undergoes rigorous testing to ensure metallurgical integrity and compliance with international standards. Our production facilities maintain strict quality control to guarantee optimal wire diameter uniformity, precise chemistry, and dependable mechanical properties. Whether used in marine fabrication, petrochemical plants, pharmaceutical equipment, or food processing facilities, this welding wire ensures reliable performance and defect-free joints.

As a versatile stainless steel filler metal, ER316/316H MIG & TIG wire combines weldability, strength, and resistance in one solution. Professionals across industries rely on it for critical applications that demand both corrosion protection and long-term durability. Choose Metals And Welding Specialities for a welding wire that meets the toughest specifications, performs under pressure, and delivers consistent, high-quality results every time.

For optimal results, use ER316/316H filler wire with argon or argon-based shielding gases to ensure smooth, stable arcs and superior penetration. Its unique metallurgical composition prevents dilution effects that typically reduce strength in mixed-metal welds. When durability, safety, and performance are non-negotiable, ER316/316H stands as a dependable solution engineered to exceed expectations in demanding welding environments.
