When comparing prices for different stainless steel grades, current market conditions still hugely favor the use of Lean Duplexes. Potential weight savings is an extra bonus.
The current strong market for sheets and plates in grades 304 and 316 has resulted in very high prices and lack of materials available. A contributing factor to this is also the strong prices for raw materials as nickel, chromium and molybdenum. There also exist alternative grades available.
To a great extent, Lean Duplex grades 1.4162 and 1.4362 can replace 304 and 316.
Pricing of Lean Duplex grades is more stable and currently very attractive.
Thanks to the chemical analysis and heat treatment, Lean duplex has both very high mechanical properties and also extremely good resistance against corrosion.
In many designs, it is possible to significantly reduce the thickness of the plates used, compared to the standard grades, making savings even greater.
Sverdrup Steel stocks both coils and sheets/plates of both 1.4162 and 1.4362 in widths 1500mm and 2000mm.
