STAINLESS STEEL//ER309LSi

Description

ER309LSi is a low-carbon, silicon-enhanced stainless steel welding wire designed for welding 309, 309L, and similar stainless steel alloys. The silicon content enhances the welding process by improving arc stability, reducing spatter, and ensuring a smoother, higher-quality weld. This wire is especially suitable for high-speed welding and is widely used in industries where high strength and corrosion resistance are crucial.

KEY FEATURES

---

• Low Carbon Content: Contains less than 0.03% carbon, which minimizes the risk of carbide precipitation and ensures better weld integrity, especially for applications exposed to high temperatures.
• Superior Corrosion Resistance: Provides outstanding resistance to corrosion and oxidation, especially in environments where high temperatures and aggressive chemicals are present.
• High Strength and Durability: Offers good tensile strength and high-temperature strength, ensuring durability in demanding applications.
• Perfect for High-Speed Automated Production: The added silicon improves arc stability, reduces spatter, and enhances weld appearance, making it easier to achieve smooth, consistent welds, especially in automated welding processes.
• All position welding
• Suitable for Marine Engineering，Chemical and Petrochemical Industry，Power Generation，Food and Dairy Industry
• Shielding gas: (TIG)100%Ar , (MIG)Ar+1-2%O₂
