ASTM Standards:
ASME Standards:
Materials provided in accordance with this specification shall comply with the requirements of Specification A961 and the additional requirements specified in the purchase order. If failure to comply with A961/A961M. it means material note comply with ASTM A694. And if this specification is inconsistent with the specification A 961, this specification shall be primary followed.
Heat treatment
All forgings should be heat treated. The heat treatment of carbon steel and high-strength low-alloy steel should be normalized, normalized or tempered or quenched and tempered. The heat treatment of alloy steel is aging treatment with quenching and precipitation or aging treatment with quenching and precipitation.
Tempering temperature shall be at least 1000 ℉ [540 ℃], precipitation heat treatment of alloy steel shall be in range from 1000 to 1225 ℉ [540 ℃ to 665 ℃].
The smelting analysis shall be carried out in accordance with the provisions of Specification A961, and the results of the analysis shall comply with the chemical composition requirements given in Table 2.
