Heat-Resistant Alloys for Ordnance Materiel and Aircraft and Naval Engine Parts (N-102): Part 1 - Heat Resistant Alloys of the 21%Cr:9%Ni Type

Abstract

Investigations were made to determine the elevated-temperature characteristics of heat-resisting alloys such as 18%Cr:8%Ni stainless steel. To improve oxidation resistance, the Cr level of 18:8 was raised to 19-22%, and to provide austenite stabilization, the nickel range was set at 8.5-10.5% and 0.07-0.11% N included. Compositions of this type are quite strong and ductile at 1800 deg F, and may become brittle in the range from 1200-1600 deg F with change of design stress. The chief value of this material is in the heat-resistant alloy field, but it is also suitable for applications that require a strong, tough, machinable, noncorrosive and nonmagnetic metal.
