    * The Following must be included with the ASTM designation and graded for the description to be complete:
    WP (S) = Seamless
    WP (W) = Welded
    WP (WX) = Welded with 100% x-ray
    WP (U) = Welded with 100% Ultrasonic examination
    CR = Corrosion resistant in acordance with MSS SP-43

    Nickel Alloy Specifications especially in pipe and tube refer only to the UNS number for material identification. Classes and Grades are occasionally used to identify options for items such as NDT, heat treatment or different methods employed when welding with filler metal such as single welded or double welded. These options do not result in an additional UNS number in the nickel materials.

    When availability of starting material is a problem, some manufacturers will offer valves machined from INCOLOY® 825 B/SB425 bar. Customer approval may be required.

    Grades/Classes/Identification Symbols are shown in this table only when they are used for material identification.

    Data in this table (except for Valve Castings) was taken from the 2013 editions, Section One Volume 01.01 and Section Two Volume 02.04, of the annual book of ASTM Standards. Casting Specification Data was from Volume 01.02, same edition.
Refer to ASME B & PV Code Section II for non-identical A/SA and B/SB requirements.
