Billets, blooms and ingots in stainless steels

The Alleima manufacturing portfolio of billets and blooms includes a wide range of stainless steels and nickel alloys. Several grades of Alleima stainless steel are available as Sanmac ^®, stainless steel with excellent machinability and consistent properties for increased cutting speeds and reduced tool wear and shorter set-up times.

Technical data, such as chemical composition and mechanical properties, is found in the material datasheet for the respective grade.
