Therefore, the addition of strong nitride forming elements, those with a stronger affinity for nitrogen than Cb and V, as deoxidation agents, interferes with these high-temperature strengthening mechanisms. Additional alloy steels that may better fulfill certain types of service will be considered for inclusion in this specification by the committee as the need becomes apparent.

This abstract is a brief summary of the referenced standard. V and Cb contribute to precipitation strengthening by forming? V also precipitates as VN during tempering or during creep.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Note 3 — The committee formulating this specification has included nine grades of materials that are considered astk represent basic types of ferritic alloy steels q217 for valves, flanges, fittings, and other pressure-containing parts. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Since these grades possess varying degrees of suitability for high-temperature and corrosion-resistant service, it is also the responsibility of the purchaser to determine which grade shall be furnished, due consideration being given to the requirements of the applicable construction codes.

Failure to comply with the general requirements of Speci? Major repairs shall be inspected to the same quality standards that are used to inspect the castings.
