We supply high-quality ER310L stainless steel welding wires in various diameters and packaging options to meet the demands of fabrication, petrochemical, power generation, furnace, and high-temperature industries. Our products are supplied across India and exported worldwide to the USA, Europe, the Middle East, Africa, and Southeast Asia.
ER310L is a low-carbon, high-chromium, high-nickel austenitic stainless steel welding wire designed for high-temperature applications. It offers excellent oxidation resistance, superior weld strength, and improved resistance to intergranular corrosion compared to standard ER310.
SS ER310L wires are solid stainless steel filler wires used primarily in TIG (GTAW) and MIG (GMAW) welding processes. The designation stands for:
The reduced carbon content helps minimize carbide precipitation during welding, thereby reducing the risk of intergranular corrosion in the heat-affected zone.
ER310L wires are mainly used for welding high-temperature stainless steels and for applications requiring excellent oxidation resistance.
Key Features of SS ER310L Wires
These features make ER310L an ideal filler material for extreme heat and furnace-related applications.
| Element | Composition (%) |

| Sulfur (S) | 0.03 max |
| Iron (Fe) | Balance |
Role of Key Elements
The high chromium and nickel content ensures stable weld deposits even at elevated temperatures.
Typical mechanical properties of deposited weld metal:
The weld metal maintains strength and structural integrity under high-temperature conditions.
ER310L weld metal performs reliably under cyclic heating and cooling.
SS ER310L weld deposits provide:
Due to its high chromium content, ER310L forms a stable protective oxide layer that prevents rapid scaling at elevated temperatures.
SS ER310L wires are widely used in:
Suitable Base Metals:
ER310L is particularly suitable for welding components exposed to extreme heat.
Preheating is generally not required for stainless steel. Post-weld heat treatment is typically unnecessary unless specified for specific applications.
SS ER310L wires are manufactured according to international standards:
