ASTM A774\/A774M-09<\/h3>\n

Historical Standard: Standard Specification for As-Welded Wrought Austenitic Stainless Steel Fittings for General Corrosive Service at Low and Moderate Temperatures<\/h4>\n
\n

ASTM A774\/A774M<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This specification covers five grades of as-welded, wrought austenitic stainless steel fittings for low-pressure piping and intended for low and moderate temperatures and general corrosive service. Users should note that certain corrosive conditions may restrict the use of one or more grades. For applications requiring a product that requires heat treatment or full pressure rating, refer to Specification A403\/A403M. The term \u201c<\/span>fittings\u201d<\/span> applies to butt and socket welding parts such as 45\u00b0<\/span> and 90\u00b0<\/span> elbows, tees, reducers, wyes, laterals, crosses, and stub ends.<\/p>\n

1.2 This specification covers as-welded fittings 3 through 48 in. [75 through 1225 mm] in outside diameter and in nominal wall thicknesses 0.062 through 0.500 in. [1.6 through 12.7 mm]. Table 1 and Table 2 list the common diameters and nominal thicknesses of fittings in this specification.<\/p>\n

1.3 This specification does not apply to cast fittings. Cast austenitic steel fittings are covered by Specification A351\/A351M.<\/p>\n

1.4 Optional supplementary requirements are provided for fittings where a greater degree of examination is desired. These supplementary requirements call for additional tests. When desired, one or more of these may be specified in the order.<\/p>\n

1.5 This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable \u201c<\/span>M\u201d<\/span> specification designation (SI units), the material shall be furnished to inch-pound units.<\/p>\n

1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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.<\/p>\n
