Description
Weld Star – ER 2594 S Stainless Wire (1.2mm) 15kg
The Weld Star – ER 2594 S Stainless Wire is an austenitic-ferritic duplex stainless steel wire crafted for welding purposes. It offers unparalleled resistance to intergranular corrosion, pitting, and stress corrosion cracking. This wire is especially favored in applications where resistance to aggressive environments is paramount. Its unique composition provides matching chemistry and mechanical property characteristics to wrought super duplex alloys, such as 2507 and Zeron 100. Furthermore, the presence of Cu and W in the alloy grants it superior resistance to certain acids compared to similar alloys without these additions.
Key Features:
- Tailored for welding all grades of super duplex stainless steels.
- Provides matching chemistry and mechanical properties to certain wrought super duplex alloys.
- Exhibits excellent resistance to aggressive environments, pitting, and crevice corrosion.
- Especially resistant in warm seawater applications due to its unique composition.
- Enhanced resistance over austenitic stainless to erosion corrosion and fatigue.
- Precision layer-wound for consistent and superior wire feeding characteristics.
Typical Applications:
The ER 2594 S Stainless Wire is a top choice for industries and applications that prioritize corrosion resistance and high-quality welds:
- Oil and Gas Industries: For equipment and pipelines that handle corrosive substances and operate under extreme pressures.
- Seawater Systems: For structures and equipment that are continuously exposed to seawater and require resistance to marine conditions.
- Petrochemical: For machinery and pipelines that handle and process chemicals.
- Pharmaceutical Industries: For equipment that needs to maintain purity and resist corrosion from various chemicals.
- Others: Including applications in the pulp and paper sectors, where corrosion resistance is crucial.
