Parts.
1. Scope 1.1 This specification covers ferritic steel forgings for boilers, pressure vessels, high-temperature parts, and associ- ated equipment. 1.2 Forgings made of steel grades listed in Specification A335/A335M, may also be ordered under this specification. The chemical, tensile, heat treatment, and marking require- ments of Specification A335/A335M shall apply, except the forging shall conform to the chemical requirements ofTables 1 and 2 of Specification A335/A335M only with respect to heat analysis. On product analysis they may deviate from these limits to the extent permitted in Table 1 of this specification. 1.3 Supplementary Requirements S1 to S9 are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order. 1.4 Unless the order specifies the applicable “M” specifica- tion designation, the material shall be furnished to the inch- pound units. 1.5 Specification A336/A336M formerly included austenitic steel forgings, which are now found in Specification A965/ A965M. 1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

3. Ordering Information and General Requirements 3.1 In addition to the ordering information required by Specification A788/A788M, the purchaser should include with the inquiry and order the following information: 3.1.1 Adrawing or sketch that shows test locations when the testing is in accordance with 8.1.1.3. 3.1.2 The intended use of forgings if 5.1 is applicable. 3.2 Material supplied to this specification shall conform to the requirements of Specification A788/A788M, which out- lines additional ordering information, manufacturing requirements, testing and retesting methods and procedures, marking, certification, product analysis variations, and addi- tional supplementary requirements. 3.3 If the requirements of this specification are in conflict with the requirements of Specification A788/A788M, the requirements of this specification shall prevail. 3.4 For hubbed flatheads and tube sheets ordered for ASME Boiler and Pressure Vessel Code application, Supplementary Requirement S12 of Specification A788/A788M shall be specified. 3.5 At the purchaser’s request the forgings shall be rough machined before heat treatment (5.2). 3.6 For Section III, Part NB of the ASME Boiler and Pressure Vessel Code application, Supplementary Requirement S3 shall be specified.ASME SA-336 SA-336M pdf download.
