TOKO AWS A5.28 ER80S-Ni2 Welding Wire
TOKO 80S-Ni2 is for welding fine grained and low alloy nickel steels producing highimpact values even at low temperature such as -80° F. 80S-Ni2 wire normally used in applicationswhich will produce a chemical composition of 2-2.5 % nickel yielding strengths ranging from 80-100 ksi. Steels commonly welded with this grade would include weathering steels (where color match is not required), ship building, off shore platform rigging and many other similar needs.
Key Advantages
- AWS A5.28 Certified: Conforms to American Welding Society specifications for carbon and low-alloy steel gas metal arc welding.
- Nickel-Enhanced: Contains ~2% nickel for enhanced low-temperature toughness.
- High Strength: Minimum tensile strength of 80ksi (80,000 psi).
- Copper Coated: Enhances electrical conductivity and reduces contact tip wear.
- Low-Temperature Performance: Excellent toughness at temperatures as low as -50°C/-60°F.
Performance Benefits
- High Toughness at Low Temperatures: Nickel content ensures ductility and resistance to brittle fracture in subzero environments.
- Smooth Metal Transfer: Stable arc with minimal spatter in spray or globular transfer modes.
- All-Position Welding: Suitable for various welding positions with proper technique.
- Minimal Post-Weld Cleanup: Low spatter results in cleaner welds.
Common Applications
- Cryogenic storage tanks and LNG infrastructure
- Arctic pipelines and offshore platforms
- Shipbuilding and marine applications
- Heavy machinery operating in cold climates
- High-strength, low-temperature steel welding
