Spring steel tape (301) 50 mm x 5 Meter

Precision Spring Steel tape

Precision tapes or metal foils made of spring steel CrNi - hard steel - 301 are used inter alia. in mechanical engineering as underlay foils, for aligning workpieces in grinding machines, adjusting games (assembly of workpieces) or measuring gap dimensions.

Properties material 301

With this material, high strength is achieved by cold rolling. Compared to material 1.4301, a much higher tensile strength can be achieved.

Therefore, the material is very well suited for stainless precision gauges and shims as well as for stainless springs and parts with higher strength.

Due to the alloy with chrome and nickel, this spring steel has good corrosion resistance. Material 1.4404 should be used in a corrosive environment.

If no special requirements are placed on corrosion, the material 1.1274 can also be used.

Technical information

The thickness tolerance is defined according to DIN EN 9445 table 1 or T3 (for strength class 15-1700 N / mm²).

Like other austenitic stainless steels, this steel is very easy to weld. However, the heat input at the weld seam can lead to a structural change (which reduces the strength) and, among other things, local corrosion of the weld seam.

With material 1.4310, when bending or bending, make sure that the bends should always run across the rolling direction. When used as a flat spring, the rolling direction must also be observed.
