SURFACE QUALITY EN-ISO 6931-1

The surface of the stainless steel 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 stainless steel wire 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.
