Description
Weld Star – ER 2594 S Stainless Wire (1.0mm) 15kg
The Weld Star – ER 2594 S Stainless Wire (1.0mm) is a meticulously crafted austenitic-ferritic duplex stainless steel wire designed specifically for welding applications. It boasts an outstanding resistance to intergranular corrosion, pitting, and stress corrosion cracking. This wire is particularly esteemed in sectors where high resistance to aggressive environments is a prerequisite. Its unique alloy composition ensures it aligns with the chemistry and mechanical properties of wrought super duplex alloys, notably 2507 and Zeron 100. Additionally, the incorporation of Cu and W in the alloy bestows it with enhanced resistance to certain acids, setting it apart from similar alloys lacking these elements.
Key Features:
- Engineered for welding all grades of super duplex stainless steels.
- Aligns with the chemistry and mechanical properties of specific wrought super duplex alloys.
- Offers unparalleled resistance to aggressive environments, pitting, and crevice corrosion.
- Especially adept in warm seawater applications due to its specialized composition.
- The presence of Cu and W enhances its resistance to sulphuric and hydrochloric acids.
- Demonstrates superior resistance to erosion corrosion and fatigue compared to austenitic stainless.
- Precision layer-wound for optimal and consistent wire feeding.
Typical Applications:
The ER 2594 S Stainless Wire is a preferred choice for industries and applications that prioritize corrosion resistance and high-quality welds:
- Oil and Gas Industries: Ideal for equipment and pipelines that handle corrosive substances and operate under challenging conditions.
- Seawater Systems: Perfect for structures and machinery that are constantly exposed to seawater and need to resist marine conditions.
- Petrochemical: Suitable for equipment and pipelines that process and handle chemicals.
- Pharmaceutical Industries: Optimal for machinery that must maintain purity and resist corrosion from diverse chemicals.
- Pulp and Paper: For applications where corrosion resistance is of utmost importance.
