Note:
A. These properties apply to forgings having a cross section no greater than 3 in.2
(1935 mm2). Mechanical properties of forgings having greater cross sections shall be
negotiated between the manufacturer and the purchaser.
B. Material is identical to the corresponding numeric grade (that is, Grade F-2H = Grade F-2) except for the higher guaranteed minimum UTS, and may be dual certified
with its corresponding numeric grade. Grade F-2H, F-7H, F-16H, and F-26H are intended primarily for pressure vessel use.
C. The H grades were added in response to a user association request based on its study of over 5200 commercial Grade 2, 7, 16, and 26 test reports where over 99 %
met the 58 ksi minimum UTS.
D. Properties for material in transformed-beta condition.
E. Properties for material in the solution treated condition.
F. Properties for solution treated and aged condition-Moderate strength (determined by aging temperature).
G. Properties for solution treated and aged condition-High Strength (determined by aging temperature).
H. For product section or wall thickness values <1.0 in. I For product section or wall thickness values ≤1.0 in.
† Tensile strength for Grade F-3 and F-4 was corrected editorially.

Note:
A. Analysis shall be completed for all elements listed in this table for each grade. The analysis results for the elements not quantified in the table need not be reported
unless the concentration level is greater than 0.1 % each or 0.4 % total.
B. Lower hydrogen may be obtained by negotiation with the manufacturer.
C. Final product analysis.
D. Need not be reported.
E. A residual is an element present in a metal or an alloy in small quantities and is inherent to the manufacturing process but not added intentionally. In titanium these
elements include aluminum, vanadium, tin, chromium, molybdenum, niobium, zirconium, hafnium, bismuth, ruthenium, palladium, yttrium, copper, silicon, cobalt, tantalum,
nickel, boron, manganese, and tungsten.
F. The purchaser may, in his written purchase order, request analysis for specific residual elements not listed in this specification.
G. The percentage of titanium is determined by difference.
