Your Aastm Profile lists the documents that will be monitored. When chromium is present as an alloying element, each class shall be subdivided into types designated as follows: Any combination of these alloying elements that assists in resisting oxidation or surface deterioration or in stabilizing the structure or retaining strength at elevated temperatures, may be used.

Some are suitable for long service at the lower temperatures only, unless low stresses are involved. Permission rights to photocopy the standard may also be secured from the ASTM website www.
