316 Stainless Steel Tubing are molybdenum-bearing austenitic stainless steel, which are more resistant to general corrosion and pitting corrosion, crevice corrosion than the conventional chromium-nickel austenitic stainless steel such as 304. 316L Stainless Steel also offer higher creep, stress-to-rupture, and tensile strength at elevated temperature.

Standard Specifications Grade Bar W/S Pipe W/S Tube Fittings Duplex Steel Price Per Kg, Duplex Stainless Steel Super duplex steel grades are S31200, S32760, S31260, S32900, S32550, S32950 and S32750. Super duplex stainless steel microstructure is a mixture of ferrite and austenite components. Super duplex stainless steel is a very tough and sturdy duplex steel, which is highly corrosion resistant.
316 in the same given conditions, reducing leakage and downtime and increasing safety by over 60%. Why selecting Steel 6Mo grade over Super duplex grades? Choose 6Mo for improved corrosion resistance and super duplex for increased strength. The higher strength of super duplex grades can make this material more susceptible Plate and sheet - Amardeep Steel CentreStainless Steel 253 MA Sheets; Duplex & Super Duplex Products.

The main difference is that Super Duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades.

Also sold as Alloy 2507, this alloy is used in situations where exceptional strength and corrosion resistance are in demand. Some of the applications and industries that utilize Duplex 2507 include:Chemical process industries Heat exchangers, vessels, and piping Desalination plants and other saltwater applications  Super Duplex Stainless Steel Pipe SDSS Seamless and The super duplex and the 316 are different types of stainless steel materials. The 316 is an austenitic stainless steel which allows welding with filler materials. The super duplex grades are also welded with filler materials. Usually, the filler materials have lessor carbon content than the original welded material.
