ESAB OK Tigrod 385 TIG Welding Rod
The ESAB OK Tigrod 385 is a high-performance TIG welding rod. It is designed for welding austenitic stainless steels such as 20% Cr, 25% Ni, 4.5% Mo, and 1.5% Cu. This rod offers superior corrosion resistance, particularly against stress corrosion and intergranular corrosion. Its exceptional performance in nonoxidizing acids makes it ideal for welding applications where exposure to aggressive chemicals is common. With better resistance to pitting and crevice corrosion than standard 18Cr-8Ni-Mo stainless steels, OK Tigrod 385 is the ideal choice for industries that prioritize durability and long-lasting protection against corrosion.
Key Features of ESAB OK Tigrod 385
- Superior Corrosion Resistance: Excellent resistance to stress corrosion, intergranular corrosion, and attack by nonoxidizing acids.
- Pitting and Crevice Corrosion Protection: Enhanced resistance compared to standard 18Cr-8Ni-Mo steels, ideal for aggressive environments.
- High Tensile Strength: Welded joints maintain tensile strength of 540 MPa, ensuring strong, reliable welds.
- Austenitic Alloy Composition: Contains 20% Cr, 25% Ni, 4.5% Mo, and 1.5% Cu, designed for strength and durability.
- Low Carbon Content: Minimizes carbide precipitation, reducing the risk of corrosion in high-temperature applications.
Key Industry Applications
- Chemical Processing: Provides corrosion-resistant welds in environments where equipment is exposed to aggressive chemicals and acids. Ideal for tanks, pipes, and containers used in chemical plants.
- Pharmaceutical Industry: Ensures long-lasting, hygienic welds in pharmaceutical equipment, where cleanliness and resistance to corrosion from acids are critical.
- Food and Beverage Production: Protects against corrosion in stainless steel equipment used for food processing, where exposure to acids and cleaning agents is common.
- Marine and Offshore: Ensures durable welds in offshore platforms, ships, and marine equipment exposed to seawater and corrosive environments.
- Power Generation: Used in the fabrication of heat exchangers and pressure vessels, where corrosion resistance is essential for maintaining operational efficiency.
