Description
Super Duplex Stainless Steel TIG Rods Steel – 1.6 mm x 5 Kg
Super Duplex Stainless Steel TIG Rods are solid, bare TIG filler rods designed for welding austenitic-ferritic stainless alloys. These rods are specifically tailored for alloys with 25% Cr, 7% Ni, 4% Mo, and low carbon content, ensuring high resistance to various forms of corrosion, including intergranular corrosion, stress corrosion, and pitting. Given its robust properties, Super Duplex is a preferred choice in industries where corrosion resistance is paramount.
Features and Benefits:
- High Corrosion Resistance: Offers resistance to general, intergranular, and stress corrosion, as well as pitting.
- Versatile Welding Positions: Suitable for all positions, excluding vertical down.
- Optimized for Austenitic-Ferritic Alloys: Tailored for alloys with specific chromium, nickel, and molybdenum content.
- Strong Mechanical Properties: Provides a yield strength of >660 N/mm² and an ultimate tensile strength of >835 N/mm².
- Impact Resilience: Features an impact strength of 200J at -20°C.
- Sour Application Suitability: Ideal for sour applications where exposure to corrosive media is frequent.
Common Applications:
- Offshore and Gas Industry: For pipelines and other infrastructure exposed to seawater and corrosive gases.
- Chemical Industries: Suitable for environments with aggressive chemicals and high corrosion potential.
- Pulp and Paper Industry: Used in machinery and infrastructure exposed to corrosive chemicals.
- Sour Pipelines: Especially popular for pipelines in sour environments.
- General Sheet and Pipe Applications: For structures requiring a strong bond and high corrosion resistance.
