Standard Specification for General Requirements for Ferritic Alloy Steel, Austenitic Alloy Steel, and Stainless Steel Tubes
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 | ASTM DesignationA |
---|---|
Seamless Carbon-Molybdenum Alloy-Steel Boiler and Superheater Tubes | A 209/A 209M |
Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes | A 213/A 213M |
Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes | A 249/A 249M |
Electric-Resistance-Welded Ferritic Alloy-Steel Boiler and Superheater Tubes | A 250/A 250M |
Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service | A 268/A 268M |
Seamless and Welded Austenitic Stainless Steel Tubing for General Service | A 269 |
Seamless and Welded Austenitic Stainless Steel Sanitary Tubing | A 270 |
Seamless and Welded Carbon and Alloy-Steel Tubes for Low-Temperature Service | A 334/A 334M |
Welded Austenitic Stainless Steel Feedwater Heater Tubes | A 668/A 668M |
Austenitic Stainless Steel Tubing for Breeder Reactor Core Components | A 771/A 771M |
Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service | A 789/A 789M |
Welded Ferritic Stainless Steel Feedwater Heater Tubes | A 803/A 803M |
Austenitic and Ferritic Stainless Steel Duct Tubes for Breeder Reactor Core Components | A 826/A 826M |
High-Frequency Induction Welded, Unannealed Austenitic Steel Condenser Tubes | A 851 |
A These designations refer to the latest issue of the respective specifications.
1.2 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.
