(1) Only a few hours, with little or no load applied (2) After these periods mechanical properties reduce by approx 50%. Note, however, that service temperatures are load and time dependant. (3) Test specimen 1.6mm thick unless otherwise stated. 'A' No attack 'B' Mild attack by absorption 'C' Dimensional change due to absorption 'D' Decomposition in short time 'E' In steam - at 160°C, decomposition after short time
