Cost-efficient alternative to traditional austenitic stainless steel 316L/1.4404 – suitable for replacing standard grades in many applications, and easy to switch. Supra 316plus (EN 1.4420, UNS S31655) – the new generation of stainless steel, created for long life and the demands of tomorrow.
Supra 316plus austenitic stainless steel (1.4420, UNS S31655) is effectively a ‘drop-in’ replacement for 316L/4404. Outokumpu will provide you with extensive commercial and technical support to ensure a smooth transition.
Five key stages in the transition
Investigation
Establish potential performance and cost benefits
Evaluation
Sampling and testing
Prototyping
Realistic manufacturing tests on key properties
Commercial
Confirm costings and commence volume production
Refinement
Explore future potential for performance improvement
The Langh Group needed a corrosion resistant steel for its liquid transport containers. The properties of Supra 316plus enabled the use of a thinner wall thickness – meaning a lower overall container weight – while excellent corrosion resistance enables transportation of aggressive liquids.
Developed by Outokumpu, Supra 316plus is a unique product that provides a competitive alternative to 316L. Supra 316plus contains less nickel and molybdenum than 316L, but more chromium and nitrogen. That gives it improved corrosion resistance and higher strength.
Read the success storyParcitank, one of Europe’s leading manufacturers of storage tanks, has explored Outokumpu’s Supra 316plus for making its wine tanks.
As wine ferments, it produces carbon dioxide gas that rises to the top. Therefore, the upper part of the tank is made usually of 316 stainless steel and the rest of the tank is made of 304.
Supra 316plus offered an interesting alternative to 316L as a new high-chromium austenitic stainless steel grade. In particular, it offers better corrosion resistance and higher strength.
