| AWS E2594T1-1/T1-4 Flux Core Wire Application & uses |
|
The AWS E2594T1-1/T1-4 flux-cored wires are made from super duplex stainless steel and contain around 25% chromium, 9–10% nickel, 4% molybdenum, and controlled nitrogen. This carefully balanced alloying results in a duplex microstructure that boasts very high tensile and yield strength along with excellent impact toughness. The weld metal produced offers remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. These wires guarantee stable arc performance, a smooth bead shape, and high deposition rates, making them suitable for all-position welding.
