201 Stainless Steel wire

This austenitic chromium-nickel-manganese stainless steel wire was developed mid-century to conserve nickel. Alloy 201 can

be used as an alternative to alloy 301 in some tempered applications. Because of the relatively high yield strength in the annealed condition, the use of alloy 201 is limited in this condition. Alloy 201 is generally used in the tempered condition particularly for springs and fasteners.


Standard Wire Finishes

Extra Clean: Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”

Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications

Soap (round wire only): Soap is used as a lubricant in the drawing process andis not removed. It acts as a lubricant during customer part forming operation. A soap finish is available in tempered products.

Plated: Many plating options are available.
