1. This specification covers seamless austenitic steel pipe intended for high-temperature central-station service. Among the grades covered are H grades and nitrogen grades that are specifically intended for high-temperature service.
2. Optional supplementary requirements (S1 through S10) are provided.
3. Grades TP321 and TP321H have lower strength requirements for nominal wall thicknesses greater than 3/8 in. [9.5 mm].
4. The dimensionless designators NPS (nominal pipe size) and DN (Diametre Nominel) have been substituted in this standard for such traditional terms as “nominal diameter,” “size,” and “nominal size.”
