This Recommended Practice establishes a weld hardness limitation to prevent in-service cracking of welds on P-1 steel equipment used in the refining industry. Information is also given on the three primary factors believed related to in-service cracking of carbon steel welds. These factors are corrosive environment, hardness, and total stress.

Unless otherwise indicated, the hardness limitation given in this Standard is to be applied to refinery pressure vessels, heat exchangers, tanks, and piping constructed of steels specifically classified as P-1 group nos. 1 and 2(except SA-266 Class 3, SA-299, SA-414 grade G, SA-455 Types I and II) in the 1974 edition of the ASME Code~ Section IX, in the ANSI Piping Code 831.3, I 973 edition, and in API Standard 650 Fifth Edition (7 /73).
