Spring steel C75 (1.1248) is characterized by excellent strength, high wear resistance, good toughness, and medium corrosion resistance. The material is used, among other things, for form springs, leaf springs, spring clips, retaining springs, and flat springs. Available from Auremo.
For the width and length of a sheet metal cut-to-size, the tolerance is +/-2mm
Important: Sheet metal cut-to-size pieces are not suitable for decorative or visible areas. Cutting is done with a guillotine shear. Edges are sharp! Not all sheets are in protective film. Surface is pure industrial quality - scratches cannot be ruled out! Please request separately in advance - we will try to find a solution for you.

- Delivery time - depending on the parcel service. Please see the FAQ.
Please note: Cut-to-size is done with a table shear. Cutting tolerance +/- 2mm.
The sheet metal surface is not suitable for decorative or visible areas. Surface is pure industrial quality - scratches cannot be ruled out.
Construction steel C75 is a simple spring steel with a high carbon content (up to 0.8%). By additionally incorporating chromium into the structure, the metal’s work-hardening capability can be increased. The main advantage of steel C75 is its strength of 640 Rm.
Spring steel sheets made of C75 can be easily formed before heat treatment. After heat treatment, the strength of the spring steel lies between 1400 and 1600 N/mm².
The spring-back when bending hardened spring steel is considerable and must be taken into account when designing the tools. Stamping and cold bending are cold forming processes that can adversely affect spring-back. To restore the original elasticity, the workpieces must be tempered after cold forming for ½ to 1 hour at 225 °C.
The maximum service temperature of spring band steel 1.1248 should not exceed 200 °C. Please note that the values of the modulus of elasticity decrease as temperature increases.
