include such elements as molybdenum, chromium and vanadium. For
temperatures up to about 500°C a carbon-0.5% molybdenum steel might be
used, up to about 525°C a 1% chromium-0.5% molybdenum steel, up to
about 550°C a 0.5% chromium-molybdenum-vanadium steel, and up to
about 600°C a steel with 5 to 12% chromium. Titanium alloys are also widely
used in this temperature range. The alpha-beta alloy 6% aluminium-4%
vanadium (IMI318) (see Chapter 13) is used up to about 450°C. Near alpha
alloys can be used to higher temperatures, for example the alloy with 5.5%
aluminium-3.5% tin, 3% zirconium-1% niobium-O.25% molybdenum ...
