Appl. No.:

12/721844

Inventors:

Richard B. Frank - Reading PA, US
Lyndon W. Burleson - Orangeburg SC, US

International Classification:

C22F 1/00
C22C 30/00

US Classification:

148707, 148442

Abstract:

A method of making steel wire is described that includes the step of forming a length of wire from a high strength, corrosion resistant alloy. The alloy preferably has the following composition in weight percent.The balance of the alloy is cobalt and usual impurities. The wire is annealed at a combination of temperature and time effective to provide a grain size of about ASTM 6 or finer. The annealed wire is then drawn such that the cross-sectional area of the wire is reduced by about 50 to 80%. The as-drawn wire is then heat treated at a second combination of temperature and time effective to provide the wire with high strength and sufficient ductility that when the wire is wrapped to provide a coil having an inside diameter substantially commensurate with the diameter of the wire and then unwrapped it does not crack or break.
