Made to the tightest tolerances
Precision strip is produced in a wide range of standard and specialty stainless steel grades. The most common grades are austenitic and ferritic. Martensitic precipitation hardenening (PH) stainless steel Dura 6908 (also known as Ultrafort 1.6908) precision strips are also available; duplex grades are available on request.
All of our products are manufactured to tightly defined tolerances in tension strength, flatness, surface texture, and more. Product dimensions range from 3 to less than 650 mm in width and from 0.05 to 1.5 mm in thickness. Outokumpu stainless steel precision strip is available with embossed surfaces, deburred edges, fully rounded edges, as spooled material, endless strip, and galvanized.
We offer our customers precision strip products, which are manufactured to tightly defined tolerances in tension strength, flatness, surface texture, and more. The special properties of the precision strip can be targeted to specific applications, including yield strength, tensile strength, grain size, and even isotropy.
Electroslag remelted (ESR) material is used when particularly clean steel is required. For high strength and optimized spring properties, the stainless precision strip is available in a wide variety of designs and finishes.

| 2H – Work hardened | 0.002–0.06 | 0.118–24.803 |
The availability of specific surface finish and dimension combination depends on the steel grade.
Coils with inside diameter of 200, 300, 400 and 500 mm depending on strip width and thickness. Other coil inside diameters on request. Coil weight up to 10 kg/mm strip width. Can also be supplied on spools on request.
Width and thickness tolerances to EN 10258 (formerly DIN 59381). Closer tolerances can be agreed on.
Check Stainless Steel Finder to view different stainless steel grades, thickness and width ranges, and available finishes by product form based on EN and ASTM standards. You’ll also find information about stainless steel grades’ corrosion resistance, mechanical strength, elongation, and other properties.
