- 1.1 This specification2 covers ferritic steel forgings for boilers, pressure vessels, high-temperature parts, and associated 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 requirements of Specification A335/A335M shall apply, except the forging shall conform to the chemical requirements of Tables 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 S10 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” specification designation, the material shall be furnished to the inchpound 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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
