Premium Low-Alloy Steel TIG Welding Wire | AWS A5.28 ER80S-D2 | 1.6mm (1/16") Diameter
Product Overview
This ER80S-D2 TIG filler wire is a manganese-molybdenum (Mn-Mo) low-alloy steel welding rod engineered for high-strength, low-alloy steel fabrication. Manufactured to meet AWS A5.28 / ASME SFA-5.28 classification standards, this 1.6mm precision-cut TIG rod delivers consistent arc performance, minimal spatter, and superior weld bead quality for GTAW (Gas Tungsten Arc Welding) applications.
Key Features
- AWS Classification: ER80S-D2 (Mn-Mo alloy filler wire)
- Diameter: 1.6mm (0.063"/1/16") — ideal for medium-thickness sections
- Alloy Composition: Manganese-Molybdenum enhanced for higher tensile strength
- Straight-length TIG rods for smooth, controlled feeding
- Minimum Tensile Strength: ~80,000 PSI (550 MPa)
- Excellent bead wetting with clean, uniform weld deposits
- Low spatter, low porosity for high-quality finish welds
- Smooth surface finish for consistent arc starts and stable arc control
Applications
- Welding of high-strength low-alloy (HSLA) steels
- Pressure vessels, boilers, and piping systems
- Structural steel fabrication requiring higher tensile properties
- Mining and heavy equipment component repair
- Oil & gas pipeline and fitting fabrication
- General fabrication where 80 ksi tensile strength is specified
Why Choose ER80S-D2 TIG Wire?
The added molybdenum content improves strength and creep resistance at elevated temperatures, making this filler wire a preferred choice for applications demanding higher mechanical properties than standard ER70S-series wires. The 1.6mm diameter offers a versatile balance between deposition rate and control, suitable for both manual and automated TIG welding processes.
