Duplex and Super Duplex Stainless Steel – Welding Wire

Duplex / Super Duplex Wire & Steel is more durable in both tensile strength and overall performance compared to traditional stainless steel grades. This superior performance is due to its lighter yet stronger composition. Duplex steels get their name from their unique two-phase microstructure, consisting of 50% austenitic and 50% ferritic stainless steel grains.

Super Duplex stainless steel offers even greater strength and corrosion resistance than standard duplex steel, thanks to the addition of chromium, nitrogen, and molybdenum. These wires are widely used in the oil and gas industry, heat exchangers, offshore platforms, chemical processing equipment, boilers, and pressure vessels.

At Shree Kailaji Alloys, as a leading Duplex & Super Duplex Wire – Supplier & Importer, we use advanced technology and strict quality control measures to manufacture high-quality Duplex & Super Duplex Welding Wires. As importers of duplex and super duplex consumables from top brands, we provide a wide range of options tailored to meet your specific industrial applications.
