Corrosion Resistant Magnetic Alloy An Article Made Therefrom And A Method Of Using Same

View page
US Patent:
6616125, Sep 9, 2003
Filed:
Jun 14, 2001
Appl. No.:
09/880974
Inventors:
Robert S. Brown - Leesport PA
Leslie L. Harner - Fleetwood PA
Assignee:
CRS Holdings, Inc. - Wilmington DE
International Classification:
F16K 3100
US Classification:
251368, 251 65
Abstract:
A corrosion resistant, soft magnetic, ferritic steel alloy, a useful article made therefrom, and a method of using the alloy are described. The alloy has the following composition in weight percent. The balance is essentially iron and the usual impurities found in similar grades of ferritic stainless steels. In accordance with another aspect of this invention, there is disclosed a magnetic component for a magnetically actuated device such as a solenoid valve wherein the magnetic component is formed of the aforesaid alloy. In accordance with a further aspect of this invention, there is disclosed a solenoid valve that incorporates a movable magnetic core that is formed of the aforesaid alloy.

US Patent:
48532983, Aug 1, 1989
Filed:
Dec 10, 1987
Appl. No.:
7/132702
Inventors:
Leslie L. Harner - Fleetwood PA
Earl L. Frantz - Reading PA
Assignee:
Carpenter Technology Corporation - Reading PA
International Classification:
C03C 2702
US Classification:
428630
Abstract:
A thermally stable Super Invar has a substantially suppressed martensitic transformation inception point as well as an average coefficient of thermal expansion substantially lower than Invar. The composition in weight percent consists essentially of ______________________________________ w/o ______________________________________ C 0. 02 Max. Mn 0. 4-0. 8 Si up to 0. 25 Ni 32. 0-33. 2 Co 4. 5-5. 5 ______________________________________ and the balance iron except for incidental amounts of other elements including up to 0. 015 w/o P, 0. 015 w/o S, 0. 25 w/o Cr, 0. 20 w/o Mo, 0. 20 w/o. Cu, as well as other incidental elements in amounts which do not undesirably affect the austenitic microstructure or otherwise detract from the desired properties of the alloy. The composition is particularly suited for the manufacture of precision optical articles as well as other articles where minimal expansion mismatch between a metal member and a nonmetal member is required at temperatures of -90. degree. C. (-130. degree. F.
