Passionate about precision — promising the strictest of tolerances

We offer precision strips ranging from 3 to 650 mm in width and 0.05 to 1.5 mm in thickness that adhere to remarkably tight tolerances — in every parameter ranging from tension strength and thickness to flatness and surface structure.

 

Tailormade thin strips engineered to meet your needs

Outokumpu’s precision strips are an ideal choice for demanding applications in the medical, automotive, energy, and household electronics sectors.

Each of our precision strips is meticulously crafted to order. We offer a diverse range of 30 to 40 different grades, with a focus on delivering individualized solutions that align seamlessly with each industry’s distinct needs. The special properties of precision strips can be targeted to specific applications, including yield strength, tensile strength, grain size, and even isotropy.

Outokumpu stainless steel production unit Dahlerbrück in Schalksmühle, Germany, offers high-performance stainless precision strip.

Our range meets rigorous formability and usage criteria, including high corrosion resistance in sectors like oil and gas, material purity for medical applications demand, and ultra-thin strips for fuel cell production.

 

Delivering precision across a comprehensive selection of grades

Outokumpu has the largest stainless steel portfolio in the market — we can deliver precision strips in any grade of stainless steel. Our wide range includes common grades such as austenitic and ferritic, apart from specialized grades that include martensitic precipitation-hardening (PH) stainless steel Dura 6908 (Ultrafort 1.6908), and Duplex grades upon request.
