Related Specifications

Scope

ASTM A336 specification covers ferritic steel forgings for boilers, pressure vessels, high-temperature parts, and associated equipment.
Forgings made of steel grades listed in Specification A 335/A 335M, may also be ordered under this specification. The chemical, tensile, heat treatment, and marking requirements of Specification A 335/A 335M shall apply, except the forging shall conform to the chemical requirements of Tables 1 and 2 of Specification A 335/A 335M only with respect to heat analysis. On check analysis they may deviate from these limits to the extent permitted in Table 1 of this specification
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.
Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inchpound units.

A The present Grade F 5A (0.25 %, maximum carbon) previous to 1955 was assigned the identification symbol F 5. Identification symbol F 5 has been assigned to the 0.15 %, maximum, carbon grade to be consistent with ASTM specifications for other products such as pipe, tubing, bolting, welding, fittings, etc. B For Grade F 22V, rare earth metals (REM may be added in place of calcium subject to agreement between the producer and the purchaser. In that case the total amount of REM shall be determined and reported. † Editorially corrected.

ASTM A336 Heat Treatment

The steel forgings shall be annealed or normalized and tempered but alternatively may be liquid quenched and tempered when mutually agreed upon between the manufacturer and the purchaser. Grade F22V forgings shall be normalized and tempered or liquid quenched and tempered. For Grade F22V forgings the minimum austenizing temperature shall be 1650°F [900°C]. For Grade F91 and F911 forgings the austenitizing temperature shall be in the range of 1900 to 2000°F [1040 to 1095°C]. Normalizing or liquid quenching shall be followed by tempering at a subcritical temperature. The minimum tempering temperature shall be 1100°F [595°C], except for the following grades:
