Introduction
EN 10270-3 specifies
stainless spring steel wire for the manufacture of springs and other components
requiring high strength, corrosion resistance and suitable spring properties.
The standard covers stainless steel wire grades supplied in different strength
classes and surface conditions.

Mechanical Properties
The mechanical requirements
of EN 10270-3 depend strongly on wire diameter, tensile strength class and
delivery condition. Spring wire is supplied to specified tensile-strength
ranges rather than one universal value for each grade.
Typical tensile-strength
levels for stainless spring wire can extend from approximately 1,200 MPa to
above 2,000 MPa for smaller diameters and higher strength classes.
Surface Finish
EN 10270-3 stainless spring
wire may be supplied with different surface conditions according to the
specified product and order requirements.
- Bright Surface
- Polished Surface
- Pickled Surface
- Descaled Surface
- Cold Drawn Surface
- Precision Finished Surface
Surface quality is
particularly important for springs because scratches, seams or other surface
imperfections can act as stress concentrators during cyclic loading.
Standard Wire Sizes
EN 10270-3 spring wire is
available in a broad range of diameters.
- Fine Wire
- Small Diameter Wire
- Medium Diameter Wire
- Large Diameter Spring Wire
- Precision Diameter Wire
- Custom Diameter Wire
Wire diameter, dimensional
tolerance and permissible deviations are selected according to the applicable
standard requirements.

Fabrication and Forming
EN 10270-3 stainless spring
wire can be coiled, formed and fabricated into springs and wire components
using appropriate equipment. The forming process should be selected according
to the grade, wire diameter and required spring properties.
Cold forming can introduce
additional stresses, so suitable stress-relieving or heat-treatment procedures
may be required after forming.
Heat Treatment
Heat treatment requirements
depend on the stainless steel grade.
Austenitic spring-wire grades
may require stress-relieving treatment after forming, while
precipitation-hardening grades can be heat treated to obtain higher strength.
The heat-treatment procedure
should be selected according to the specific material grade and manufacturer's
recommendations.
