High-alloy electrodes 309L-17

309L-17 electrodes are austenitic stainless steel electrodes with reduced carbon content. They are intended for welding stainless steels to non-alloy and low-alloy carbon steels, as well as for surfacing components exposed to corrosion or high temperatures. The low carbon content minimizes the risk of intergranular corrosion.

Key advantages:

• High corrosion resistance – ideal for use in chemically aggressive or humid environments.
• Stable arc and smooth weld – easy electrode handling and aesthetic weld appearance.
• Low carbon content – increases joint durability.
• Excellent weldability – steady arc performance, easy striking and re-striking.
• Material versatility – suitable for joining different types of steels (e.g., stainless to carbon steel).

Applications:

• Welding stainless steel to carbon steel
• Joining stainless to structural steels (heterogeneous joints)
• Surfacing of worn or corrosion-exposed components
• Chemical, petrochemical, and food industry structures
• Power industry, pipelines, tanks, furnace housings
