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.

  • Stainless Spring Steel Strip (1.4310)
  • Carbon Spring Steel Strip (Hardened & Tempered; +QT)
  • Carbon Spring Steel Strip (Annealed; +LC)

For stainless spring steel strip we predominantly stock material-no. 1.4310. You can order this material as strips or sheets.
 
Our special strength is a distinctive stock of wide strips (mostly with a width of 300 mm) in a variety of thicknesses and tensile strengths. Strips with a thickness of 0,50 mm or higher are also stocked as sheets with a length of 2 m.

Information
  • to produce slit coils a minimum width/thickness ratio of 3:1 is needed.
  • Stainless steel according to EN 10151 has a chrome proportion of at least 16% and a nickel proportion of at least 6%.
  • X10CrNi18-8 is an austenitic steel, the tensile strength derives from the cold rolling process.
  • this steel is especially suited to produce springs and reaches the highest possible tensile strengths.
Heat Treatment
  • after the forming process of the spring the tensile strength can be increased by heat Treatment.
  • the heat treatment also smoothes out the tensions of the forming process.
  • the DIN recommendation reaches from annealing at 250°C for 24 hours to 450°C for 30 minutes; cooling down by air.
  • the maximum possible temperature of usage is between 120°C and 250°C (dependent upon load).
