ASTM B739-03(R2018) pdf free download.Standard Specification for Nickel-Iron-Chromium-Silicon Alloy Welded Tube
1. Scope
1.1 This specification covers alloys UNS N08330 and UNS N08332 in the form of welded tube intended for heat resisting applications and general corrosive service. 1.2 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. 1.3 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 Safety Data Sheet (SDS) 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. 1.4 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. General Requirement
3.1 Material furnished under this specification shall con- form to the applicable requirements of Specification B751 unless otherwise provided herein.
4. Ordering Information
4.1 It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under this specification. Examples of such requirements include, but are not limited to, the following: 4.1.1 Alloy (Table 1), 4.1.2 ASTM designation and year of issue, 4.1.3 Dimensions (outside or inside diameter and nominal wall thickness), 4.1.4 Length (specific or random), 4.1.5 Quantity (feet or number of pieces), 4.1.6 Certification—State if certification is required, 4.1.7 Samples for Product (Check) Analysis—State whether samples for product (check) analysis should be furnished, and 4.1.8 Purchaser Inspection—If purchaser wishes to witness tests or inspection of material at place of manufacture, the purchase order must so state indicating which tests or inspec- tions are to be witnessed.
5. Materials and Manufacture
5.1 The tube shall be made from flat-rolled alloy conform- ing to Specification B536, by an automatic welding process with no addition of filler metal. Subsequent to welding and prior to final heat treatment, the tube shall be cold-worked either in both weld and base metal or in weld metal only.
6. Chemical Composition
6.1 The material shall conform to the requirements, as to chemical composition specified in Table 2. 6.2 If a product (check) analysis is performed by the purchaser, the material shall conform to the product (check) analysis variations per Specification B751.
7. Mechanical Properties and Other Requirements
7.1 The tensile properties of the material at room tempera- ture shall conform to those shown in Table 1. 7.2 Grain Size—Annealed Alloy UNS N08332 shall con- form to an average grain size of ASTM No. 5 or coarser. 7.3 Annealing Temperature—Alloy UNS N08330 shall be annealed at 1900°F (1040°C) minimum. Alloy UNS N08332 shall be annealed at 2050°F (1120°C) minimum.
