Description
Washington Alloy Stainless Steel Flux-Cored wires were developed for use with 100% CO2 or 80% Ar/20% CO2 shielding gas. The ability of operating over a wide range of current setting permits deposition rates that are nearly 4 times greater than covered electrodes and up to 50% greater than solid MIG wire. Although the cost per pound of Stainless Steel Flux-Cored wires may be more than that of coated electrodes or solid MIG wire, your cost per pound of deposited weld metal is greatly reduced because of the higher deposition efficiency and lower operational costs. The true stainless steel sheath used in manufacturing Washington Alloy Flux-Cored Stainless is your guarantee of smooth performance, x-ray quality welds and a beautiful stainless steel bead appearance. Spatter is extremely low and slag is self-peeling.

Applications
All-position welding of AISI 301, 302, 304, and 308. Produces an austenitic (non-magnetic) 19% Chromium – 9% Nickel weld deposit with a controlled ferrite.

Similar to 308HT0-1/-4 but the lower carbon content in the weld deposit greatly reduces the possibility of intergranular corrosion caused by carbide precipitation. Commonly used on AISI 301, 302, 304, 304L, and 308L.

All-position welding of 25% Chromium – 12% Nickel Stainless Steel. Commonly used on dissimilar metals such as joining stainless steel to carbon or low alloy steel and for welding the clad side of 18-8 stainless clad steels.

Better corrosion resistance than 309T0-1/-4, due to the lower carbon content of the weld deposit. Excellent crack resistance and oxidation resistance at extreme temperatures. Typical applications include furnaces, kiln linings, 309 wrought or cast parts.

For joining dissimilar metals of stainless steel to carbon and low alloy steels. Most commonly used as a buffer layer when cladding mild steel with 316 austenitic stainless.

For welding 18% Chromium –12% Nickel – 2.5% Molybdenum Stainless Steel. The addition of Molybdenum gives added creep resistance at elevated temperatures and corrosion resistance against “pitting” that may be caused by sulfuric and sulfurous acids, phosphoric acids and acetic acids.

An all-position wire similar to 316T0-1/-4 however the lower carbon content of the weld metal provides protection against intergranular corrosion due to carbide precipitation. Commonly used in industries that manufacture rayon, dyes, paper, ink, rubber, bleaches, photographic chemicals.

All-position welding of austenitic 18% Chromium – 12% Nickel – 3.5% Molybdenum Stainless Steel which is subjected to severely corrosive acids such as sulfuric or sulfurous acids and their salts. Excellent resistance to corrosion and pitting.

For Columbium stabilized grades of AISI 347 and 321 or 18/8 grades of austenitic stainless subjected to temperatures above 750oF but less than 1550oF. Also available in a low carbon grade (E347LT0-1/-4) with a carbon level average of .03.

For welding AISI 403, 405, and 410 Chromium steel. Primarily used as an overlay on carbon steel to give added resistance against corrosion, erosion or abrasion on valve seats and parts. Preheat and Postheat treatment is required for most applications.

All-position welding of 409, 410, 410S and 405 stainless steel. Less crack sensitive than 410T0-1/-4. Primarily used for repairing and welding CA6NM castings such as found in fluid handling equipment, valves and pump parts. Postweld heat treatment required.

For welding base metals of similar analysis. 11% Chromium with 0.70% titanium as a stabilizer.
