ASTM A336/A336M-99e1
(Specification)Standard Specification for Alloy Steel Forgings for Pressure and High-Temperature Parts
Standard Specification for Alloy Steel Forgings for Pressure and High-Temperature Parts
SCOPE
1.1 This specification covers both ferritic and austenitic 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 Table 1 of Specification A335/A335M only with respect to heat analysis. On check analysis they may deviate from these limits to the extent permitted in Table 2 of this specification. Note 1- For all austenitic steels, the term "Class" has been changed to "Grade." Current Formerly Grade F1 Class F1 Grade F11, Class 2 Class F11 Grade F11, Class 3 Class F11A Grade F11, Class 1 Class F11B Grade F12 Class F12 Grade F5 Class F5 Grade F5A Class F5A Grade F9 Class F9 Grade F6 Class F6 Grade F21, Class 1 Class F21A Grade F21, Class 3 Class F21 Grade F22, Class 1 Class F22A Grade F22, Class 3 Class F22 Grade F91 Class F91 Grade F3V Class F3V Grade F22V Class F22V
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 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as standards. Within the text and tables, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Combining values from the two systems may result in nonconformance with the specification.
1.5 Unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inch-pound units.
