Information about alloy surcharges

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.

  • Tool Steel, low alloyed, Hot Rolled, Annealed (75Cr1+AC)
  • Tool Steel, Low Alloyed, Bright Hardened And Tempered (75Cr1+QT)

Do you need spring steel but the needed dimensions are beyond the manufacturing dimensions?
In this case 75Cr1 might be a possible alternative. Its chemical analysis is comparable to C75S – the most popular spring steel quality.
With 75Cr1 you have got the advantage of expanded widths and thicknesses.
75Cr1 is available in hardening grades: annealed, 42-44 HRC and 48-50 HRC.
