The alloy surcharge is a price component for alloyed stainless steels which is charged in addition to the basic price by steel producers. The alloy surcharge is updated monthly. The alloy surcharge depends on the price development of the alloying elements, the exchange rates and the product type. Thus, a separate alloy surcharge is shown for wire, cold wide strip and the more expensive cold strip (precision strip). Spring steel strip is generally referred to as precision strip. In the case of spring steel strip with the material number 1.4310, a further distinction is made between normal strip and strip with an increased molybdenum content.
All information in mm.
Usually strips are produced at normal or fine tolerance. Precision tolerance is available on demand.
