Order and delivery
We confirm your order in writing. Single coils or regular call-offs; minimum quantities depend on grade and size and are stated in the quotation.
Frequently asked questions
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.
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.
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.
