100mm 400mm 304 Stainless Steel Pipe Tube ASTM Brushed Finish
Grades of Stainless Steel
Super Duplex Steel
With a PREN range of 38-45, super duplex steel was created for use in the oil & gas industry and the chemical industry. This grade of steel is stronger and far more corrosive resistant but is more difficult and more costly to process than standard duplex steel. This is typically grade EN 1.4410.
Duplex 2507 Stainless Steel
Duplex 2507 stainless steel is another form of super duplex steel. This material is made with 25% chromium, 4% molybdenum, and 7% nickel. This type of stainless steel is known for its resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion.
Zeron 100 Stainless Steel
Zeron stainless steel is a super duplex stainless steel that was developed by Rolled Alloys. It contains 25% chromium, 7% nickel, 3.6% molybdenum, along with copper and tungsten additions.
Lean Duplex Grades
Lean duplex steel has a PREN range of 22-27 and was created for use in less demanding applications such as general building and construction. While the corrosion resistance is going to be similar to standard austenitic steel, it has better strength and mechanical properties.
Applications of Duplex Stainless Steel
Duplex stainless steels are very commonly used in more demanding applications due to their corrosion resistance properties, high mechanical properties, and how strong the material is. This makes the material very popular in a wide variety of industries.
