SURFACE QUALITY EN 10270-3

The surface of the wire must be smooth and, insofar as is possible, free of scratches, pitting and other surface defects that may make the wire unusable. The alternating torsion test is one method that makes it possible to detect surface discontinuities.
If the wire is to be used for manufacturing springs that are used for high stresses, the special surface quality requirements and tests can be agreed on the customer's instruction when the quote is requested or the order is placed.
Surface Finishes for Wires for Springs:
Soap S-Co Standard coating

Special soap coating SS-Co / S-Co+

Improvement of the spring coiling
Bright Bright surface appearance, although there is a thin layer of soap
Polished Wet drawn
Dulll nickel plating Dry drawn
Bright nickel plating Wet drawn

 

SURFACE QUALITY EN 10088-3

Minor surface irregularities that are inherent to the manufacturing process are permitted. When necessary, it is possible to agree on more specific surface quality requirements when placing the order, based on the EN 10221 Standard.
