Our product finder will help you to find out the best product. Simply answer the following questions:

Choose the desired cross section:

When it comes to round spring steel wire You can choose between carbon steel or stainless steel:

spring steel wire (patented drawn)
Material Code SH (used to be: "Sorte C")
Tensile strength Depending on the diameter, find a table here
Diameter 0,2-18 mm
Product coils, spools, straightened bars

 

spring steel wire (stainless)
Material Code 1.4310 (X10CrNi18-8)
  Material 1.4404, 1.4401, 1.4571 is available on demand
Tensile strength Depending on the diameter, find a table here
Diameter 0,2-16 mm
Product Coils, spools, straightened bars

 

Those products are flat spring steel with a thickness of less than 3 or 4 mm:

carbon spring steel strip (annealed)
Material C75S/C85S+LC
Standard tensile strengths 490-640 N/mm²
Dimensions From 0,05 mm thickness to max. 4 x 200 mm
If you need wider Dimensions maybe 75Cr1 is an alternative
Product Strips and sheets
Optional: round Edges

 

carbon spring steel strip (hardened & tempered)
Material C75S/C85S+QT
Standard tensile strengths 1320-1520 N/mm²
1570-1770 N/mm²
not that common but possible:
1100-1300 N/mm² and further ranges
Dimensions From 0,02 mm thickness to max. 3 x 230 mm and 4 x 30 mm
If you need wider Dimensions maybe 75Cr1 is an alternative
Product Strips and sheets
Optional: round Edges
