... material values. For investigations under compressed conditions, the compression set was determined for specimens of ACM, FKM and HNBR after exposure in heating oil B0 and B20 for 3,7,14, 28, 56 and 90 days at 40 °C according to ISO 815-1. It was found that the resistance in B20 at 40 °C was given for all...

...]. A key issue is that microturbine exhaust gas contains water vapor which could decrease the oxidation lifetime of Cr 2 O 3 -forming alloys such as S30400 or N06625 due to the formation of volatile CrO 2 (OH) 2 [8, 9]. Greater Cr depletion was reported for the S30403 steel coupon after 679 h of exposure...
