Kencotube is one of the renowned manufacturer & exporter of high quality Duplex Steel Sheets and Plates, which are the family of steels that have a mixed micro-structure of 50% ferrite and 50% austenite. Ferritic-austenitic stainless steel also referred to as Duplex Stainless Steel Sheets, combine many of the beneficial properties of ferritic and austenitic steels. Duplex Stainless Steel Plates offers excellent resistant to corrosion and very high mechanical strength. The layer in these Duplex Stainless Steel Textured Sheets prevents further corrosion by blocking oxygen diffusion to the steel surface and stops corrosion from spreading into the bulk of the metal. The high corrosion resistance of Duplex Stainless Steel Coils ensures significantly more uptime than carbon steels and conventional stainless steels, while the mechanical strength allows for lighter constructions, more compact system design and less welding.
Duplex Stainless Steel Perforated Sheets has high amount of chromium and a slight amount of nickel, where it is called as 'duplex' because it combines both austenitic (chromium-nickel) and ferritic (chromium only) molecular structures. As their names imply, Duplex Stainless Steel Hairline Sheets consist mainly of one phase, austenite or ferrite. Although these types in Duplex Stainless Steel Etching Sheets are fine for a wide range of applications, there are some important technical weaknesses in both types. Duplex Stainless Steel Designer Sheets are known to offer exceptional strength and astounding aesthetic qualities along with better resistance against corrosion and high temperature, superior hygienic surface finishing, and improved steel recyclability.
