Duplex steel coil is an alloy of steel composed of ferritic and austenitic microstructures. It has superior strength, corrosion resistance, and wear-resistant properties due to its dual-phase composition. Additionally, it features high yield strength and good workability under different temperature ranges. The most common grade used in the making of duplex steel coils is 2205, which contains 21% chromium, 5% nickel, 3.2% molybdenum, and 0.14%-0.20% nitrogen for improved weldability and corrosion resistance compared to plain carbon steels or other alloys.
Duplex Steel Coil is a ferritic-austenitic stainless steel alloy with excellent corrosion resistance, tensile strength, and high durability. Its superior mechanical properties make it well-suited for use in pressure vessels, piping systems, and other forms of structural components. It resists chloride pitting and stress-corrosion cracking, making it an ideal material for industrial applications involving corrosive environments. In addition to its strength, duplex stainless steel has good weldability, further enhancing its potential uses, such as flooring panels and chemical processing equipment.
