Tensile strength classes to EN 10151
Cold-rolled spring strip is specified by tensile strength class. How high the class can go depends on the thickness; the class and the certificate values are confirmed in our quotation. Annealed strip or your own tensile range on request.
- C850850–1,000 MPa
- C10001,000–1,150 MPa
- C11501,150–1,300 MPa
- C13001,300–1,500 MPa
- C15001,500–1,700 MPa
- C17001,700–1,900 MPa
- C19001,900–2,200 MPa
Strip edges
Strip comes with a slit edge unless you ask for another. For a deburred or rounded edge, give the burr limit or the edge profile in your enquiry and we confirm it for your size.
- Slit edgeDefaultThe edge as cut by the slitter, with a small burr on one side.
- Deburred edgeOn requestBurr removed and the corners slightly broken.
- Rounded edgeOn requestA full radius across the thickness, for strip that is handled by hand or must not cut.

Frequently asked questions
Which tempers are there for 1.4310 spring strip?
The EN 10151 tensile strength classes from C850 (850–1,000 MPa) to C1900 (1,900–2,200 MPa). The highest class depends on the thickness. Strip can also be rolled to your own tensile range or supplied annealed.
What is the difference between normal and precision tolerance?
EN ISO 9445-1 gives two tolerance classes for narrow strip. For 0.30 mm strip below 125 mm wide, the thickness tolerance is ±0.020 mm in the normal class and ±0.010 mm in the precision class. State the class you need in your enquiry.
What edge will the strip have?
A slit edge, unless you ask for another. Deburred or rounded edges are available on request: tell us the burr limit or the edge profile you need and we confirm it for your size.
Which certificates come with the strip?
EN 10204 3.1 certificates with the chemical analysis and the mechanical properties of the agreed temper. Inspection certificates 3.2 on request, agreed before we quote. The certificate type and the origin are stated for each lot in our quotation.
