Assignee:

Huntington Alloys, Inc. - Huntington WV

International Classification:

C22C 1903

US Classification:

420459

Abstract:

In an age hardenable controlled expansion alloy essentially devoid of chromium, the combination of short term tensile properties and elevated temperature properties, particularly notch rupture strength, are improved by the inclusion therein of silicon in an amount leass than 1%.

Assignee:

Huntington Alloys, Inc. - Huntington WV

International Classification:

C22C 3848

US Classification:

148 32

Abstract:

Matrix-stiffened nickel-iron-chromium-columbium solid-solution alloy with excellent metallurgical stability has heat-resistant and corrosion resistant characteristics especially useful for articles needed to sustain stress in long-time service at elevated temperatures, particularly including superheater tubing in steam power plants. Alloy also has good workability and thermal response characteristics for commercial production of heat-treated wrought products.
