Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.

Stainless steel wire 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.
