    1. Scope

    p>1.1 This specification covers a group of common requirements that, unless otherwise specified in the individual product specification, shall apply to steel forgings under any of the following specifications issued by ASTM:

    ASTMDesignationTitleA 266 Forgings, Carbon Steel for Pressure Vessel ComponentsA 288 Carbon and Alloy Steel Forgings for Magnetic Retaining Rings for Turbine Generators A 289 Alloy Steel Forgings for Nonmagnetic Retaining Rings for GeneratorsA 290 Carbon and Alloy Steel Forgings for Rings for Reduction GearsA 291 Carbon and Alloy Steel Forgings for Pinions and Gears for Reduction Gears A 336 Steel Forgings, Alloy, for Pressure and High-Temperature Parts A 372 Carbon and Alloy Steel Forgings for Thin-Walled Pressure Vessels A 427Wrought Alloy Steel Rolls for Cold and Hot ReductionA 469 Vacuum-Treated Steel Forgings for Generator RotorsA 470 Vacuum-Treated Carbon and Alloy Steel Forgings for Turbine Rotors and Shafts A 471Vacuum-Treated Alloy Steel Forgings for Turbine Rotor Disks and Wheels A 508/A 508M Quenched and Tempered Vacuum-Treated Carbon and Alloy Steel Forgings Pressure VesselsA 521 Steel Closed-Impression Die Forgings for General Industrial UseA 541/A 541M Steel Forgings, Carbon and Alloy, Quenched and Tempered, for Pressure Vessel ComponentsA 579 Superstrength Alloy Steel ForgingsA 592 High-Strength Quenched and Tempered Low-Alloy Steel Forged Fittings and Parts for Pressure VesselsA 649/A 649M Forged Steel Rolls Used for Corrugating Paper Machinery A 668/A 668M Steel Forgings Carbon and Alloy for General Industrial UseA 723/A 723M Alloy Steel Forgings for High-Strength Pressure Component ApplicationA 765/A 765M Carbon Steel and Low-Alloy Steel Pressure Vessel Component Forgings with Mandatory Toughness RequirementsA 768 Vacuum-Treated 12 % Chromium Alloy Steel Forgings for Turbine Rotors and Shafts A 837 Steel Forgings, Alloy, For Carburizing ApplicationsA 859/A 859M Steel Forgings, Low-Carbon Age-Hardening Nickel-Copper-Chromium-Molybdenum Alloy Steel, for Pressure Vessel ComponentsA 891 Precipitation Hardening Iron Base Superalloy Forgings for Turbine Rotor Disks and Wheels A 909Specification for Steel Forgings, Microalloy, for General Industrial UseA 940Specification for Vacuum Treated Steel Forgings, Alloy, Differentially Heat Treated, for Turbine RotorsA 965/A 965MSpecification for Steel Forgings, Austenitic, for Pressure and High Temperature Parts

    1.2 In case of conflict in requirements, the requirements of the individual product specifications shall prevail over those of this specification.

    1.3 The purchaser may specify additional requirements (see ) that do not negate any of the provisions of either this specification or of the individual product specifications. The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order.

    1.4 If, by agreement, forgings are to be supplied in a partially completed condition, that is, all of the provisions of the product specification have not been filled, then the material marking (see Section ) and certification (see Section ) shall reflect the extent to which the product specification requirements have been met.
