As a reliable and sustainable material, stainless steel is used at several levels in the energy chain, from the offshore wells in the Oil and Gas industry to the hot water tank coupled with photovoltaic panels, as well as in such process industries as petrochemical and chemical, among others. The diversity of the service conditions, combined with cost efficiency, have permitted the development of a lot of different stainless steel grades.

Offer for other applications: Austenitics

The austenitic grades are the most common stainless steels. They come in all sorts of possible variants, depending on the properties required by the end-use conditions.

Aperam offers a high quality surface, especially for container applications that need to avoid any risk of fluid retention.
