![]() ![]() This specification covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels, with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes. This specification covers minimum-wall-thickness, electric-resistance-welded,carbon steel tubes to be used for heat exchangers, condensers, and similar heat-transfer apparatus. This specification covers seamless ferritic and austenitic steel boiler,superheater, and heat-exchanger tubes, designated Grades T5, TP304, etc. This specification covers tubes 1/8 to 3 in. This specification covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. Grades of steel are identified by grade numbers or by chemical composition. Cold-finished bars are suitable for heat treatment, for machining into components, or for use in the as-finished condition as shafting, or in constructional applications, or for other similar purposes. This specification covers cold-finished carbon and alloy steel bars produced in straight length and coil to chemical compositions. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized. Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. It shall be permissible to furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification. This specification covers seamless carbon steel pipe for high-temperature service in NPS 1/8 to NPS 48 inclusive, with nominal (average) wall thickness as given in ASME B 36.10M. Supplementary requirements of an optional nature are provided and shall apply only when specified by the purchaser. It shall be permissible to furnish pipe having other dimensions provided that such pipe complies with all other requirements of this specification. This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26, inclusive, with nominal wall thickness. Castings are classified on the basis of the tensile strength of the iron in separately cast test bars.Ĭlick here to access Dura-Bar's ASTM policy. This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration. ![]()
