Stainless Steel Wire

Stainless steel is a versatile material common to industrial uses such as lockwire and spring wire, and also used extensively in the medical field due to its ability to meet demanding applications at relatively low cost. Wire can be made as round or flat ribbon and finished in a variety of tempers.

Stainless lockwire conforming to NASM20995 (corrosion resistant steel) is inventoried in common sizes and offered on one to five pound spools. Medical grade stainless alloys are kept in stock for fabrication as bare or film coated wires made to customer specifications.
