Weld Star – ER 2594 Stainless TIG Wire (1.6mm) 5kg

Description

Weld Star – ER 2594 Stainless TIG Wire (1.6mm) 5kg

Weld Star – ER 2594 Stainless TIG Wire is an austenitic-ferritic duplex stainless steel wire. It boasts a PREN (Pitting Resistance Equivalent Number) of at least 40, classifying the weld metal as super duplex stainless steel. This wire is over-alloyed with nickel compared to the base material, ensuring an optimal blend of microstructure, mechanical properties, and corrosion resistance. It’s an alloy that finds its primary use in applications where corrosion resistance is paramount.

Features and Benefits:

• Super Duplex Quality: With a PREN of at least 40, this wire is classified as super duplex stainless steel.
• Corrosion Resistance: Offers excellent resistance to intergranular corrosion, pitting, and stress corrosion cracking, especially in chloride environments.
• Optimal Composition: Over-alloyed with nickel to ensure the best combination of microstructure, mechanical properties, and corrosion resistance.
• Versatile Applications: Widely used in industries where corrosion resistance is vital, such as petrochemical, offshore, pulp and paper, and pollution control equipment production.
