NOTES:(a) ASME Boiler and Pressure Vessel Code, Section II materials may also be used provided the requirements of the ASME

specification are identical to or more stringent than the corresponding ASTM specification for the Grade, Class, or Type listed.

(b) Plate materials are listed only for use as blind flanges and reducing flanges without hubs (see para. 5.1 of B16.5).Additional plate materials listed in ASME B16.34 may also be used with corresponding B16.34 Standard Classratings.

(1) Upon prolonged exposure to temperatures above 425C, the carbide phase of steel may be converted to graphite.Permissible but not recommended for prolonged use above 425C.

(2) Not to be used over 455C.




(6) Upon prolonged exposure to temperatures above 465C the carbide phase of steel may be converted to graphite
