Note B: Lower hydrogen may be obtained by negotiation with the manufacturer. Note C: Final product analysis. Note D: Need not be reported. Note 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. Note F: The purchaser may, in his written purchase order, request analysis for specific residual elements not listed in this specification.
