Kobelco - Flux Cored Wire - E2594 x 1.2

Kobelco PREMIARC DW-2594 is a premium, rutile-type all-position flux-cored welding wire (FCAW) manufactured by Kobe Steel. It is specifically engineered for high-integrity joining of super duplex stainless steels, offering a combination of high mechanical strength and exceptional corrosion resistance for harsh industrial environments.

Technical Classifications & Standards
AWS Classification: E2594T1-1/4 (under AWS A5.22).
EN ISO Standard: EN ISO 17633-A T 25 9 4 N L P C1/M21 1.
Shielding Gas Options: Can be run with either 75% Ar - 25% CO? (or an 80/20 mix) or 100% CO?. An Argon-CO? mixture is highly recommended for optimal arc performance and weld puddle control.
Polarity: DCEP (Direct Current Electrode Positive / DC+).Target Materials & Grades
The chemistry of DW-2594 is perfectly balanced with nominal levels of 25% Chromium, 9% Nickel, 4% Molybdenum, and 0.2% Nitrogen.

It is explicitly designed for welding matching super duplex alloys, including:
ASTM S32750 (EN 1.4410 / SAF 2507).
ASTM S32760 (EN 1.4501 / Zeron 100).

Key Performance Benefits
High Pitting Resistance: Formulated to produce a weld deposit with a Pitting Resistance Equivalent Number (PREN) greater than 40. This ensures the weld metal matches the parent super duplex steel's ability to resist localized pitting and crevice corrosion in chloride environments.
Excellent Ferrite-Austenite Balance: The internal flux compounds ensure the cooling weld bead achieves the critical 50/50 dual-phase microstructure (ferrite and austenite) necessary to prevent cracking and maintain mechanical toughness.
Premium Welder Usability: True to the Kobelco DW series, it operates with a highly stable, completely spatter-free arc. It leaves a bright, smooth weld bead aesthetic backed by self-releasing slag that lifts off cleanly as the weld cools.
All-Position Productivity: Features a fast-freezing rutile slag support system that allows for fast travel speeds and high deposition rates even in out-of-position vertical-up (3G) or overhead (4G) configurations.
