As a leading Chinese Incoloy alloy supplier, AEETHER manufactures and produces different sizes of Incoloy Alloy 800HT fittings. Several other alloy manufacturers entered the alloy 800H (UNS N08810) market and additional creep and rupture data became available. The Metals Property Council for ASME gathered this data and made a new analysis using parametric procedures, involving 87 heats and 1,052 data points.
