spring steel strip (stainless)

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.

Tensile strength (Rm):
  • 1100 to 1900 N/mm2
  • other tensile strengths on request
  • 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).
