ASTM C12A is equivalent to ASTM A182 Grade F91, improved 9Cr-Mo-V casting materials, the rated pressure and temperature.
Is still not listed in ANSI B16.34 - 1996 Nian version. At elevated temperatures, this material allows stress values have been enacted in the "ASME Case 2192,1995-year statute in March" in. Use of "protocols Case 2192" in the allowable stress value, and ANSI B16.34.
Appendix Form, describes the method, ASTM A217 Grade C12A rated pressure - temperature of the calculated values are listed in the following table
