ASTM A276-2017 pdf free download.Standard Speci fication for Stainless Steel Bars and Shapes
1. Scope
1.1 This specification covers hot-finished or cold-finished bars except bars for reforging (Note 1). It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels. The free-machining types (Note 2) for general corrosion resistance and high-temperature service are covered in a separate specification. N OTE 1—For bars for reforging, see Specification A314. N OTE 2—For free-machining stainless bars designed especially for optimum machinability, see Specification A582/A582M. N OTE 3—There are standards covering high nickel, chromium, auste- nitic corrosion, and heat-resisting alloy materials. These standards are under the jurisdiction of ASTM Subcommittee B02.07 and may be found in Annual Book of ASTM Standards, Vol. 02.04. 1.2 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 of this specification is specified in the order.
3. Ordering Information
3.1 It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under this specification. Such requirements may include but are not limited to the following: 3.1.1 Quantity (weight or number of pieces), 3.1.2 Name of material: stainless steel, 3.1.3 Form (bars, angles, and so forth), 3.1.4 Condition (Section 4. 1), 3.1.5 Finish (Section 8 of Specification A484/A484M), 3.1.6 Surface preparation of shapes (Section 8 of Specifica- tion A484/A484M), 3.1.7 Applicable dimensions including size， thickness, width, and length, l, 3.1.8 Cross section (round, square, and so forth), 3.1.9 Type or UNS designation (Table 1), 3.1.10 ASTM designation and date of issue, and 3.1.11 Whether bars are to be rolled as bars or cut from strip or plate. . 3.1.12 Test for magnetic permeability when specified by customer purchase order when ordering Types 201 and 205. 3.1.13 Choice of testing track from the options listed in Test Methods A1058 when material is ordered to an M suffix (SI units) product standard. If the choice of test track is not specified in the order, then the default ASTM track shall be used as noted in Test Methods A1058. 3.1.14 Supplementary requirements, and 3.1.15 Additional requirements.
4. Manufacture
4.1 Condition: 4.1.1 Bars shall be furnished in one of the following conditions listed in the Mechanical Requirements table: 4.1.1.1 Condition A—Annealed. 4.1.1.2 Condition H—Hardened and tempered at a relatively low temperature. 4.1.1.3 Condition T—Hardened and tempered at a relatively high temperature. 4.1.1.4 Condition S— Strain Hardened—Relatively light cold work. 4.1.1.5 Condition B—Relatively severe cold work. 4.1.1.6 Condition SA—Stabilized annealed.
5. Chemical Composition
5.1 The steel shall conform to the requirements for chemical composition specified in Table 1. 5.2 Methods and practices relating to chemical analysis required by this specification shall be in accordance with Test Methods, Practices, and Terminology A751.
6. Mechanical Properties Requirements
6.1 The material shall conform to the mechanical test requirements specified in Table 2. 6.2 The martensitic grades shall be capable of meeting the hardness requirements after heat treating as specified in Table 3. 6.3 Hardness measurements, when required, shall be made at a location midway between the surface and the center of the cross section.
7. Magnetic Permeability
7.1 When required by the purchase order, the magnetic permeability of Types 201 and 205 in the annealed condition shall not exceed 1.2 as tested by a Severn-type indicator.
8. General Requirements
8.1 In addition to the requirements of this specification, all requirements of the current edition of Specification A484/ A484M shall apply. Failure to comply with the general requirements of Specification A484/A484M constitutes non- conformance to this specification.
9. Certification
9.1 Upon request of the purchaser in the contract or order, the producer’s certification that the material was manufactured and tested in accordance with this specification, together with a certified report of the test results shall be furnished at the time of the shipment.
