Stainless Steel 310 Filler Wire is a high-alloy austenitic stainless steel welding consumable designed for applications requiring exceptional resistance to high temperatures, oxidation, and corrosion. Due to its high chromium and nickel content, SS 310 filler wire provides superior performance in elevated temperature environments and is commonly used in welding components that operate under extreme heat conditions.
This filler wire is widely used in welding stainless steel structures, furnace components, heat treatment equipment, and other high-temperature industrial equipment. Stainless Steel 310 filler wire offers excellent weldability and produces strong, durable weld joints with good mechanical properties.
SS 310 filler wire is specifically formulated to handle welding applications where standard stainless steel filler metals may not provide sufficient oxidation resistance. Its enhanced composition allows it to resist scaling at temperatures up to approximately 1100°C, making it suitable for industries where components are exposed to continuous heat and thermal cycling.
Manufactured according to international welding standards, Stainless Steel 310 filler wires provide stable arc characteristics, smooth feeding during welding operations, and consistent weld bead quality. These features make them highly preferred among professional welders and industrial fabricators.
Key Features of Stainless Steel 310 Filler Wire
The performance of Stainless Steel 310 filler wire is largely determined by its carefully balanced chemical composition.
Typical chemical composition includes:
| Element | Composition (%) |
|---|---|
| Chromium (Cr) | 24.0 – 26.0 |
| Nickel (Ni) | 19.0 – 22.0 |
| Carbon (C) | ≤ 0.25 |
| Manganese (Mn) | ≤ 2.0 |
| Silicon (Si) | ≤ 1.5 |
| Phosphorus (P) | ≤ 0.03 |
| Sulfur (S) | ≤ 0.02 |
| Iron (Fe) | Balance |
