    ** Listed order of Alloy Types for B/SB619, B/SB622 and B/SB626 (Ni-Cr-Mo) versus B/SB564 (Ni-Mo-Cr) is as shown in the 2013 Edition ASTM ANNUAL BOOK OF STANDARDS.


    * 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.

    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.
  • This basic group of Hastelloy products is tailored for use in specific highly corrosive environments.

  • They are widely used in various acid services in the chemical process industries.

  • Oil and gas, energy, and pharmaceutical facilities are among those that have found uses for Hastelloy products.

  • The "B" an"C" series Hastelloys are Nickel-Chrome alloys containing a high percentage of molybdenum.

  • Cobalt is also specified in all the alloys listed in this table except for Hastelloy G-2.

  • "G" and "X" Hastelloys have significant molybdenum content, in the same general range found in a 625 alloy.

  • "B-2" and "B-3" are upgrades of Hastelloy B, with Hastelloy B-3 having improved thermal stability and resistance to stress corrosion cracking.

  • All of these alloys are known for their resistance to stress corrosion cracking.
Refer to ASME B & PV Code Section II for non-identical A/SA and B/SB requirements.
