ASTM A484/A484M-06b pdf.Standard Specification for General Requirements for Stainless Steel Bars, Billets, and Forgings.
ASTM A484/A484M covers general requirements that shall apply to wrought stainless steel bars, shapes, forgings, and billets or other semi-finished material (except wire) for forging, under the latest revision of each of the following ASTM specifications: A 276, A 314, A 458, A 473, A 477, A 479/A 479M, A 564/A 564M, A 565/A 565M, A 582/A 582M, A 638/A 638M, A 705/A 705M, and A 831/A 831M.
1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by waiving a test requirement or by making a test requirement less stringent.
1.3 The requirements for introduction of new materials in specifications referencing this specification are given in .
1.4 General requirements for flat-rolled stainless steel products other than bar are covered in Specification A 480/A 480M.
1.5 General requirements for wire products in coils are covered in Specification A 555/A 555M.
1.6 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as the standard; within the text and tables, the SI units are shown in [brackets]. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.7 Unless the order specifies an “M” designation, the material shall be furnished to inch-pound units.
5. Materials and Manufacture
5. I The material shall be made by any process.
5.2 The material shall be furnished in one of the conditions detailed in the applicable product specification, for example. hot-worked: hot-worked and annealed; hot-worked, annealed. and cold-worked: or hot-worked, annealed, and heat-treated.
5.3 The material shall be furnished in one of the finishes as detailed in Section – or further described in the applicable product specification. for example. hot-finished or coldfinished.
6. Chemical Composition
6.1 Heat or Cast Analysis—The chemical analysis of each heat shall he determined in accordance with the applicable materials specification and Test Methods, Practices, and Terminology A 751.
6. I .1 The analysis of each heat shall be made from a test sample taken during the pouring of the melt or from the in-process product later in the manufacturing flow.
6. 1 .2 The heat analysis shall conform to the chemical requirements for each of the specified elements for the grade ordered, as listed in the applicable product specification.
6. 1 .3 All commercial metals contain small amounts of elements other than those which are specified. It is neither practical nor necessary to specify limits for unspecified elements. whether intentionally added unspecified elements, residual elements, or trace elements, that can be present. The producer is permitted to analyze for unspecified elements arid is permitted to report such analyses. The presence of an
12. Number of Tests and Retests
12.1 Unless otherwise specified in the product specification, one. sample per heat shall be selected for chemical analysis and one mechanical test sample shall be selected from each lot of bars and shapes and from each lot of forgings. Except for bars cut from strip or plate, tension tests of bars and shapes shall be made in the longitudinal direction. Testing for bars cut from strip or plate shall conform to the requirements of the applicable product specification for the strip or plate and to Specification A 480/A 480M.
