spring steel wire (stainless)

You can order the stainless spring steel wire as coils, spools or straightened bars. The standard lengths of the straightened rods are one, two or three meters.

The straightened bars can be cut in length according to your wishes.

Beside steel grade 1.4310 we are able to deliver 1.4401 (AISI 316) and 1.4404 (AISI 316L)!



Material Code X10CrNr18-8 (used to be: X12CrNi17-7)
Material No 1.4310 (approx. AISI 301)
Quality according to EN 10270-3
Tolerances according to EN 10270-3 and DIN EN 10218-2;
for the finish "ground and polished" EN 10278
Dimensions coils/spools: 0,10 mm to 7,00 mm diameter
bars: 0,20 mm to 24,00 mm diameter
Product coils, spools, straightened bars
Tensile strength (Rm): 1250 to 2200 N/mm2, depending on the diameter of the wire
the tensile strength of each diameter
Surface matt shining finish or polished, partial ground and polished
Information
  • the maximum possible temperature of usage is up to 250°C (dependent upon load)
information regarding the E modulus and the shear modulus information regarding the conversion of tensile strength into other units
Heat treatment
  • after the forming process of the spring the tensile strength can be increased by heat treatment (a plus of approx. 150 N/mm²)
  • the heat treatment also smoothes out the tensions of the forming process
  • the EN-Standard recommendation reaches from annealing at 250°C for 4 hours to 425°C for 30 minutes; cooling down by air
