Description
Weld Star – ER 317L Stainless TIG Wire (2.4mm) 5kg
Weld Star – ER 317L (2.4mm) is an austenitic stainless steel TIG wire designed for welding alloys with a similar chemical composition. It’s ideal for severely corrosive environments, especially where crevice and pitting corrosion are concerns. The low carbon content minimizes the risk of intergranular carbide precipitation. However, it’s not suitable for structural service above 400°C or for cryogenic applications. The weld deposit is akin to 316L but has a high molybdenum content, enhancing its corrosion resistance.
Features and Benefits:
- Austenitic Stainless Steel: Suitable for welding alloys of a similar chemical composition, ensuring compatibility and strong welds.
- Corrosion Resistance: Ideal for severely corrosive environments, offering longevity and reliability.
- Low Carbon Content: Reduces the possibilities of intergranular carbide precipitation, ensuring consistent weld quality.
- High Molybdenum Content: Similar to 316L but with enhanced corrosion resistance due to increased molybdenum.
Common Applications:
- Chemical and Petrochemical Industries: Suitable for equipment and machinery exposed to aggressive chemicals.
- Marine Environments: Ideal for marine and underwater applications due to its high corrosion resistance.
- Papermaking Industry: Used in equipment and machinery in paper production.
- Food Processing Industries: Ensures safe and corrosion-resistant welds for food processing equipment.
