Description

1.1 This specification covers 8 and 9 % nickel-alloy steel forged or rolled flanges, fittings, valves, and parts intended for use in welded pressure vessels for low-temperature service. The specification is applicable to forgings with maximum section thickness of 3 in. [75 mm] in the double normalized and tempered condition and 5 in. [125 mm] in the quenched and tempered condition. Forgings under this specification are intended for service at operating temperatures not lower than -320 ^o F [-196 ^o C] for Type I or -275 ^o F [-170 ^o C] for Type II or higher than 250 ^o F [ ^o 121C].

1.2 Material under this specification is available in two types having different chemical compositions as follows:

1.3 This specification is expressed in both inch-pound units and SI units. However, unless the order specifies the applicable ‘M’ specification designation (SI units), the material shall be furnished to inch-pound units.

1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
