This wire is used for welding and cladding applications on base filler metals such as stainless steel, nickel-chromium, and cobalt-chromium alloys. HAYNES® 617 Welding Wire is ideal for gas turbine hot components, such as combustion, high-temperature burners, and heat exchangers.

HAYNES® 617 Coated Electrode Corrosion Resistance

HAYNES® 617 Welding filler Wire is highly resistant to corrosion. It has excellent corrosion resistance in oxidizing and reducing environments, such as sulfuric and hydrochloric acids and alkaline solutions. Additionally, the wire is highly resistant to stress-corrosion cracking, a common phenomenon in austenitic stainless steel.

HAYNES® 617 Coated Electrode Heat Treatment

The HAYNES® 617  welding electrode requires proper heat treatment to ensure optimal performance. The wire must be heated to 1140°C (2085°F) and held at this temperature for at least 30 minutes before being quenched in water. The wire requires a second heat treatment between 760 and 930°C (1400 and 1700°F), followed by air cooling.


In conclusion, HAYNES® 617 Welding Wire is an incredible nickel-chromium-cobalt-molybdenum alloy with excellent mechanical and physical properties, making it ideal for high-temperature applications. It has excellent corrosion resistance to oxidizing and reducing environments and stress-corrosion cracking and is widely used in aerospace, chemical processing, power generation, and petrochemical industries.
