  • (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
