Product Features:
When Condition A is specifified, the austenitic alloys shall be heated to 1900 ±50°F (1038 ± 28°C), at which time the chromium carbide will go into the solution, be held for a sufficient time, and then be cooled at a rate sufficient to prevent precipitation of the carbide and to provide the specifified properties.
