Aminox™ & Ferrinox™

Enhanced material properties

Our own designated stainless steel bar products provide improved performance.


Enhanced Properties

In-house Products

We work closely with suppliers to develop unique products, providing enhanced chemistry and mechanical properties.


Our close partnerships with suppliers enable us to develop enhanced stainless steel, giving you improved material options. Our suppliers share our vision regarding product quality and how we market to our customers.

Designated Products

We stock Aminox AS1&rade; and Ferrinox 255LT&rade;, enhanced versions of standard stainless steel grades, and we supply both types in bar form. Aminox is based around 316L stainless steel, while Ferrinox is a super duplex grade conforming to the requirements of UNS S32550. Both alloys are subjected to much tighter controls during the production process.

Why buy our products?

By supplying our own improved material grades, we give customers improved performance options, allowing the development of components that operate in the most demanding environments.

Laboratory Support

Tensile testing is an example of one of the laboratory testing services we offer.

How many stockholders in the UK have a dedicated team of metallurgists?

To our knowledge, we are the only UK stockholder with a UKAS-Accredited Material Testing Laboratory. Our laboratory offers a comprehensive range of testing, from Charpy impact testing to tensile testing and chemical analysis.

We offer services that add value to our established material supply proposition.

Further Information

Our products are developed to push performance boundaries compared to existing commercial alloys.

Not only does the development of these alloys take a great deal of time, we take the trouble to trademark them to protect their status.

Choosing our designated product afford numerous benefits, not just in terms of performance but cost. You may be able to utilise our own alloys instead of purchasing higher specification material.
