N'GENIUS for Chemical Process Industries

The N'GENIUS Series™ is the most advanced family of materials for chemical processing infrastructure.

Conventional 300 Series austenitic stainless steels are widely used in the chemical processing industry, but their resistance to general corrosion, localised corrosion, stress corrosion cracking and erosion corrosion depends on many factors including:

• Alloy composition of the grade(s) selected for the different types of chemical process media
• Concentration of the various chemical process media
• Whether the chemical process media contains chlorides or fluorides or various impurities
• Temperature of the chemical process media.

What's more, conventional 300 Series grades of austenitic stainless steels have low mechanical strength properties relative to the N'GENIUS Series™.

Therefore, when piping systems (pipes, fittings and flanges) and engineering equipment (including tanks, vessels, pumps, valves, filters, centrifuges, mixers and agitators) are designed in accordance with the various international codes, standards and specifications using conventional austenitic stainless steels, their wall thicknesses are increased, which in turn increases the overall cost of projects.

The N'GENIUS Series™ contains an infinite number Alloy Types and Variants, providing a wide range of advanced material solutions for the chemical process industry.

This enables engineers to choose from a wide selection of N'GENIUS™ alloys which have a unique combination of mechanical and corrosion resistance properties and provide significant advantages for all major projects.

Performance benefits of the N'GENIUS ICONIC Series™ and the N'GENIUS INFINITY Series™ for chemical process industry applications include:

The Alloy Types and Variants of the N'GENIUS Series™ enables engineers to select different minimum levels of Pitting Resistance Equivalent (PRE_N / PRE_NW) to optimise the corrosion performance of the materials selected for the different chemical process environments such as Organic or Inorganic, Phosphoric Acid, Caustic and Sulphuric Acid environments containing higher concentrations or at higher temperatures.

The following is a selection of some of the N'GENIUS Series™ alloys that are well suited for pipelines, piping systems and engineering equipment applications for the chemical process industry:
