  • A333 useful information

    Other Comments

    Grade 6 is a low alloy steel similar to 4032 in properties. Tensile strength requirement for Grade 6 is 60 ksi minimum and notched-bar impact strength is 4 to 13 ft. lbs. depending upon section size.

    Scope

    ASTM A333 covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.


    Material & Manufacture

    The pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.


    Heat Treatment Requirements

    All seamless and welded pipe shall be treated to control their microstructure by the following methods: Normalizing per A 333/A 333M-05 section 4.2.1.1; section 4.2.1.2 or section 4.2.1.3 Quenched and Tempered per A 333/A 333M – 05 section 4.2.2.1 Double Normalized and Tempered per A 333/A 333M – 05 section 4.2.2.2


    Tensile Requirements

    The material shall conform to the requirements as proscribed:

    Impact Requirements

    For Grades 1, 3 and 6, the notched-bar impact properties of each set of three impact specimens, including specimens for the welded joint in welded pipe with wall thicknesses of 0.120 in. [3 mm] and larger, shall not be less than the values prescribed:

    Mechanical Testing

    Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested. For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe. Hydrostatic Test Impact Test One notched bar impact test, consisting of breaking three specimens shall be made from each heat represtented in a heat-treatment load on specimens taken from the finished pipe.


    Lengths

    Lengths required shall be specified on order. If no definite lengths required, following practice applies: Single Random — 17′ ~ 24′ lengths Double Random — 36′ ~ 44′ lengths


    Required Markings on Each Length

    (On Tags attached to each Bundle in case of Bundled Pipe) Markings will adhere to prescribed specifications in A 999/A999M and be: Rolled, Stamped, or Stenciled (Mfrs. Option) In addition, markings will include:

    Hot Finished or Cold Drawn Manufacture Name
    Specification / Grade Hydro or NDE
    Seamless or Welded
    Schedule Number
    the letters “LT” followed by the temperature at which the impact tests were made * and **
    the letters “QT” when the pipe is furnished in the quenched and tempered condition

    * except when a lower test temperature is required because of reduced specimen size, in which case, the higher impact test temperature applicable to a full size specimen would be marked ** when the size of the finished pipe is insufficient to obtain subsize impact specimens, the marking shall not include the letters “LT” followed by an indicated test temperature unless Supplementary Requirement S! is specified.

ASTM A333 Grade 7 Carbon Steel Seamless Pipe FAQ

  • How SA106 is different from A106?
    SA means that the ASTM standard has been approved / adopted by the BPVC
    (Boiler & Pressure Vessel Code by ASME).
    Examples:
    ASME says about ASTM A53: there are no differences.
    ASME says about ASTM A106: Identical, except for editorial differences at 8.1, 13.4, and 24.1 and deletion of ASTM caveat 1.5 (these are articles referring to the BPVC).
  • ASTM A333 Grade 7 Carbon Steel Seamless Pipe Special Testing is available?
    Special Testing is available upon request.
