Different variants for Duplex
Duplex stainless steels are designed to provide better corrosion resistance, in particular to stress corrosion and pitting corrosion. The microstructure leads to higher strength than standard austenitic stainless steels such as Type 304 or 316. Duplex stainless steels have become more and more popular in recent years. There are several variants available, such as Duplex 2205, Superduplex 2507 or lean duplex with lower nickel content.

Ambica Steels’ stainless steel mill employs a range of steel making technologies. It produces around 80,000tns/yr in most austenitic ferritic, martensitic and duplex grades of stainless steel, in a broad range of finished and semi-finished products which find wide ranging applications in various Industrial Sectors.
Outokumpu and Italian-based Acciaierie Valbruna SpA, have signed a non-exclusive patent and trademark license agreement, which grants Valbruna the right to use Outokumpu's LDX 2101 duplex stainless steel grade in all long products, such as bar, rebar and wire products in the European Union, Norway and Switzerland. Lean Duplex grade LDX 2101, a low-nickel, high-strength stainless steel developed and patented by Outokumpu, was commercially introduced in 2002 and has met with great success in demanding applications.
Chevron Australia Pty Ltd, a subsidiary of Chevron Corp., has awarded a USD 200 million front-end engineering and design (FEED) contract for the Gorgon LNG project to Kellogg Joint Venture Group (KJVG).
The new Origo/Aristo range of CC/CV welding machines from ESAB enables all types of stainless and mild steel to be welded, together with a range of other materials with plate thicknesses of 0.5mm and up.
Corrosion Resistance: Duplex stainless steel has excellent corrosion resistance due to its high chromium and molybdenum content. It is particularly resistant to stress corrosion cracking and pitting, which makes it suitable for use in harsh environments.
Strength: Duplex stainless steel is much stronger than conventional austenitic stainless steels, which allows for thinner and lighter constructions without sacrificing durability.
Toughness: Duplex stainless steel has a high toughness, which means it is resistant to brittle fracture and impact. This property makes it suitable for use in cryogenic applications.
Cost-effectiveness: Although duplex stainless steel is more expensive than conventional austenitic stainless steels, its superior properties can lead to cost savings in the long run by reducing maintenance and downtime.
Versatility: Duplex stainless steel can be used in a wide range of applications, including chemical processing, oil and gas, marine, and pulp and paper industries. It is also used in construction and architecture due to its aesthetic appeal.
