Abstract:

A number of high strength structural sheet alloys, plastics, and thermal insulation materials were subjected to a variety of mechanical and physical property tests over the temperature range of 78 F down to -423 F. Of the sheet alloys tested, desirable combinations of high strength, high resistance to brittle fracture, and good weldability are exhibited by the following severely cold rolled stainless steels such as Types 301, 304, and 310 although Type 301 appears marginal at liquid H temperatures, Ti A110-AT, Al alloy 5052-H38, and age hardened K-Monel. 20 cold worked Haynes 25 alloy and 40 cold rolled Hastelloy B alloy exhibit good strength and brittle fracture resistant properties at temperatures down to -423 F. Al alloy 6061-T6 has good toughness down to -320 F but exhibits moderate notch sensitivity at -423 F. The high strength Al alloys of the 2000 and 7000 series are very notch sensitive at -320 F and at -423 F. Author
