Metallic Material Limits for API Equipment Used in High Temperature Applications
Description
This document examines mechanical properties of metallic materials used for API 6A and 17D wellhead equipment for service above 250ºF. A total of eleven different alloys meeting API 6A, PSL 3 conditions were supplied “in condition” by a variety of suppliers. Materials in this test program included alloys common to the oil and gas industry. The alloys tested included low alloy steels, martensitic, precipitation hardened and duplex stainless steels, and nickel alloys. Yield strength reduction ratios at temperatures of 300, 350 , 400, and 450 ºF are reported. As a result of testing, yield strength reduction ratios at 300ºF to 450ºF ranged from 92% to 87% for the low alloy steels, 92% to 88% for the martensitic stainless steels 81% to 73% for super duplex, 99% to 89% for the precipitation hardened stainless steel and 94% to 89% for the nickel alloys. The reported results represent an average over the different heats for each type of material. These results are intended to expand the
