1.1 This specification covers four grades of carbon steel forgings for boilers, pressure vessels, and associated equipment. Note 1 -Designations have been changed as follows: Current Formerly Grade 1 Class 1 Grade 2 Class 2 Grade 3 Class 3 Grade 4 Class 4 1.2 Supplementary requirements are provided for use when additional testing or inspection is desired.
