Description

Weld Star – ER 2209 Stainless TIG Wire (2.4mm) 5kg

Weld Star – ER 2209 Stainless TIG Wire is an austenitic-ferritic duplex stainless steel wire known for its high tensile strength. It offers excellent resistance against stress corrosion, cracking, and pitting. This wire is specifically designed for joining 22% Cr duplex stainless steel base materials, notably 2205. Interestingly, the weld metal has a lower ferrite content compared to the 2205 base metals. It’s recommended for use in temperatures ranging from cryogenic levels to 300°C. This wire is predominantly used in industries like petrochemical, offshore, acid gas, and chemical transportation.

Features and Benefits:

  • Duplex Stainless Steel: Made of austenitic-ferritic duplex stainless steel, ensuring high tensile strength.
  • Corrosion Resistant: Offers excellent resistance to stress corrosion, cracking, and pitting.
  • Versatile Welding: Specifically designed for joining 22% Cr duplex stainless steel base materials, especially 2205.
  • Temperature Range: Suitable for a wide temperature range, from cryogenic levels to 300°C.
  • Industry Applications: Widely used in the petrochemical, offshore, acid gas, and chemical transportation sectors.

Common Applications:

  • Petrochemical Industry: Ideal for applications that require resistance to corrosive chemicals.
  • Offshore Operations: Suitable for offshore platforms and equipment exposed to saline environments.
  • Acid Gas Handling: Used in equipment and pipelines that handle acid gases.
  • Chemical Transportation: Ensures the durability and integrity of transportation equipment and pipelines in the chemical industry.
