Zeron 100 welding wire covers the super duplex filler-metal range used to weld Zeron 100 base material and other 25Cr super duplex grades. Two filler classifications: ER2594 (per AWS A5.9 / ISO 14343) is the overmatching filler, richer in Cr, Ni, Mo, and N than the base metal, used as the standard call for production welds where the deposit must match or exceed base-metal corrosion + mechanical properties. ER2553 is the matching-composition filler used when the weld will be solution-annealed post-deposit.
ER2594 (overmatching, AWS A5.9) · ER2553 (matching) · Spool / coil / cut-to-length
Wire rod stock (cold-drawn round wire 0.8 mm to 6.4 mm OD on spools / coils, or bare bar in 1m / 3m / 6m straight lengths) supplied for: GTAW / TIG welding (most common for super duplex), GMAW / MIG, FCAW, SAW (submerged arc on heavy plate / pipe), and orbital welding on tube/pipe joints. Wire surface finish: cold-drawn smooth bare; copper-coated available on request for MIG feeding stability.
