Product Description
E310-16 is a premium austenitic stainless steel electrode compliant with AWS A5.4/A5.4M standards, designed for welding Type 310/310S stainless steels and similar high-temperature alloys. Featuring a high-chromium composition (25.0-28.0wt.%) with 20.0-22.5wt.% nickel, it excels in high-temperature oxidizing environments. Compatible with SMAW (stick) process with DCEN or AC operation, it supports welding of similar stainless steels, dissimilar metal joints, and corrosion/heat-resistant surfacing.
Features
▪ Superior Heat Resistance: Offers exceptional resistance to oxidation at high temperatures up to 1100°C (2012°F), maintaining strength and toughness in continuous service conditions. Effectively resists thermal cycling and high-temperature corrosion in furnace and heat treatment applications.
▪ Stable Performance: Austenitic structure with excellent mechanical properties, including tensile strength of 550-620 MPa and elongation ≥30%. Weld metal exhibits good toughness and matches base material properties without complex post-weld heat treatment. Low susceptibility to sensitization and carbide precipitation.
▪ Excellent Weldability: Ensures smooth arc action with minimal spatter, easy slag removal, and flat, regular bead appearance. Compatible with DCEP (DC+) and AC polarities, it adapts to all-position welding (except vertical-down) with flexible current control for various electrode diameters.
Applications
▪ Ideal for high-temperature and corrosive environments, E310-16 is widely used in:
▪ Heat Treatment Industry: Furnace parts, heat shields, radiant tubes, and high-temperature fixtures.
▪ Chemical Processing: High-temperature reactors, reformer tubes, and acid concentration equipment.
▪ Petrochemical Industry: Cracking furnace tubes, superheater components, and high-temperature piping systems.
▪ Power Generation: Boiler components, superheater elements, and combustion chambers.
