StarBlaze TIG Wire ER2594

STARBLAZE TIG 2594 is a premium, high-alloy super duplex stainless steel TIG welding rod formulated for demanding components that experience severe mechanical stress and aggressive corrosive exposure.
Conforming to the international AWS A5.9 ER2594 standard, this solid wire is over-alloyed with nickel and enriched with nitrogen to deliver a precisely balanced austenitic-ferritic microstructure in the finished weld.

Product Overview & Composition
Alloy Classification: Strictly complies with international standards
AWS/SFA A5.9: ER2594 and EN ISO 14343-A: W 25 9 4 N L.

Chemical Profile: Features a robust, high-alloy core consisting of 25% Chromium, 10% Nickel, 4% Molybdenum, and 0.25% Nitrogen.
Microstructure Balance: The solid wire chemistry forms a 45–55% ferrite matrix embedded in austenite, optimizing the ferrite-to-austenite ratio for peak toughness.
PREN Performance: Guarantees a Pitting Resistance Equivalent Number (PREN) ? 40, cementing its status as a true high-tier "super duplex" metal.
Extreme Corrosion Resistance: Offers world-class defense against stress corrosion cracking (SCC), crevice corrosion, and heavy pitting in chloride-heavy environments.
