  • A All values are maximum unless otherwise stated. Where ellipses (...) appear in this table, there is no requirement and analysis for the element need not be determined or reported.
  • B Niobium and columbium are interchangeable names for the same element and both names are acceptable for use in A01.22 specifications.
  • C Grade F2 was formerly assigned to the 1 % chromium, 0.5 % molybdenum grade which is now Grade F12.
  • D The present Grade F5a (0.25 max carbon) previous to 1955 was assigned the identification symbol F5. Identification symbol F5 in 1955 was assigned to the 0.15 max carbon grade to be consistent with ASTM specifications for other products such as pipe, tubing, bolting, welding fittings, and the like.
  • E Applies to both heat and product analyses.
  • F For Grade F22V, rare earth metals (REM) may be added in place of calcium, subject to agreement between the producer and the purchaser. In that case the total amount of REM shall be determined and reported.
  • G The ratio of Titanium to Nitrogen shall be $ 3.5. Alternatively, in lieu of this ratio limit, Grade F23 shall have a minimum hardness of 275 HV (26 HRC, 258 HBW) in the hardened condition (see 3.2.1). Hardness testing shall be performed in accordance with 9.6.3, and the hardness testing results shall be reported on the material test report (see 18.2.5).
  • H Grade FXM-27Cb shall have a nickel plus copper content of 0.50 max %. Product analysis tolerance over the maximum specified limit for carbon and nitrogen shall be 0.002 %.
  • I Grade F316Ti shall have a titanium content not less than five times the carbon plus nitrogen content and not more than 0.70 %.
  • J Grade F321 shall have a titanium content of not less than five times the carbon plus nitrogen content and not more than 0.70 %.
  • K Grade F321H shall have a titanium content of not less than four times the carbon plus nitrogen content and not more than 0.70 %.
  • L Grades F347 and F348 shall have a niobium (columbium) content of not less than ten times the carbon content and not more than 1.10 %.
  • M Grades F347H and F348H shall have a niobium (columbium) content of not less than eight times the carbon content and not more than 1.10 %.
  • N Grade F347LN and Grade F347LNCuB shall have a niobium (columbium) content of not less than 15 times the carbon content.
  • O % Cr + 3.3 × % (Mo + 1⁄2 W) + 16 × % N = 41 min.
  • P Chromium Nickel Balance is defined as CNB = (Cr+6Si+4Mo+1.5W+11V+5Nb+9Ti+12Al) - (40C+30N+4Ni+2Mn+1Cu).
  • Q Al + Ti shall be 0.85 % min: 1.20 % max.
    R The method of analysis for nitrogen shall be a matter of agreement between purchaser and manufacturer.
