Stainless Steel Wire  1.4539

composition : X1NiCrMoCu25-20-5 According to EN 10270-7904L and AISI 904L 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 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.
