This specification covers electric fusion-welded nickel-chromium-cobalt-molybdenum alloy UNS N06617, nickel-iron-chromium-silicon alloys UNS N08330 and UNS N08332, Ni-Cr-Fe-Al Alloy (UNS N06603), Ni-Cr-Fe Alloy UNS N06025, and Ni-Cr-Fe-Si Alloy UNS N06045 pipe intended for heat resisting applications and general corrosive service. Two classes of pipes are covered: Class 1 and Class 2. The joints shall be double-welded, full-penetration welds. The weld shall be made either manually or automatically by an electric process involving the deposition of filler metal. Weld defects shall be repaired by removal to sound metal and rewelding. All pipe shall be furnished in the annealed condition. The material shall conform to the composition limits specified. Transverse tension test, transverse guided-bend weld test, pressure test, and chemical analysis shall be made to conform to the requirements specified.1.1 This specification covers electric fusion-welded nickel-chromium-cobalt-molybdenum alloy UNS N06617, nickel-iron-chromium-silicon alloys UNS N08330 and UNS N08332, Ni-Cr-Fe-Al Alloy (UNS N06603), Ni-Cr-Fe Alloy UNS N06025, and Ni-Cr-Fe-Si Alloy UNS N06045 pipe intended for heat resisting applications and general corrosive service.1.2 This specification covers pipe in sizes 3 in. (76.2 mm) nominal diameter and larger and possessing a minimum wall thickness of 0.083 in. (2.11 mm).1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers general requirements for ferritic alloy steel, austenitic alloy steel, and stainless steel tubes. The steel shall made by any process. The material shall conform to the tensile property requirements prescribed in the individual product specification. Yield strength tests and elongation tests shall be made to conform to the requirements. Flattening test, reverse flattening test, reverse bend test, flaring test, flange test, hardness test, ultrasonic test, eddy current test, flux leakage test, and hydrostatic test shall be made to conform to the requirements specified.1.1 This specification covers a group of requirements that, unless otherwise specified in an individual specification, shall apply to the ASTM product specifications noted below.Title of Specification ASTMDesignationA   Seamless Carbon-Molybdenum Alloy-Steel Boiler and Superheater Tubes A209/A209MSeamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes A213/A213MWelded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes A249/A249MElectric-Resistance-Welded Ferritic Alloy-Steel Boiler and Superheater Tubes A250/A250MSeamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service A268/A268MSeamless and Welded Austenitic Stainless Steel Tubing for General Service A269/A269MSeamless and Welded Austenitic and Ferritic/Austenitic Stainless Steel Sanitary Tubing A270/A270MSeamless and Welded Carbon and Alloy-Steel Tubes for Low-Temperature Service A334/A334MWelded Austenitic Stainless Steel Feedwater Heater Tubes A688/A688MAustenitic Stainless Steel Tubing for Breeder Reactor Core Components A771/A771MSeamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service A789/A789MSeamless and Welded Ferritic Stainless Steel Feedwater Heater Tubes A803/A803MSeamless Austenitic and Martensitic Stainless Steel Duct Tubes for Liquid Metal-Cooled Reactor Core Components A826/A826MHigh-Frequency Induction Welded, Unannealed, Austenitic Steel Condenser Tubes A851Welded Austenitic Alloy Steel Boiler, Superheater, Condenser, and Heat Exchanger Tubes with Textured Surface(s) A1098/A1098M1.2 In the case of conflict between a requirement of a product specification and a requirement of this general requirements specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this general requirements specification and a more stringent requirement of the purchase order, the purchase order shall prevail.1.3 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. The inch-pound units shall apply unless the “M” designation (SI) of the product specification is specified in the order.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products. The material shall be made by an electric melting process. It shall be made from ingots that have been reduced in cross section in such a manner and to such a degree as to ensure proper refinement of the ingot structure. Chemical composition, hardness, macrostructure and decarburization of the material shall conform to the requirements in accordance to the referenced ASTM documents itemized herein.1.1 This specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products.1.2 These products, which include hot or cold finished bar, plate, sheet, strip, rod, wire, or forgings, are normally fabricated into tools, dies, or fixtures. The selection of a material for a particular application will depend upon design, service conditions, and desired properties.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
