Designation: A 314 97 (Reapproved 2002) Standard Specifi cation for Stainless Steel Billets and Bars for Forging1 This standard is issued under the fi xed designation A 314; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1. Scope 1.1 This specifi cation covers stainless steel billets and bars intended only for forging. 2. Referenced Documents 2.1 ASTM Standards: A 484/A 484M Specifi cation for General Requirements for Stainless Steel Bars, Billets and Forgings2 A 751 Test Methods, Practices, and Terminology for Chemical Analysis of Steel Products3 E 527 Practice for Numbering Metals and Alloys (UNS)4 2.2Other Document: SAE J1086 Recommended Practice for Numbering Metals and Alloys5 3. Ordering Information 3.1 It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under this specifi cation. 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: type or UNS designation (Table 1), 3.1.3 Condition, 3.1.4 Cross section (round, round-cornered square, etc.), 3.1.5 Form: bar or forging billet, 3.1.6 Applicable dimensions, including size, thickness, width, and length, 3.1.7 ASTM designation and date of issue, 3.1.8 Preparation for delivery (see Specifi cation A 484/ A 484M), 3.1.9 Marking (see Specifi cation A 484/A 484M), and 3.1.10 Exceptions to the specifi cation or special require- ments. 3.2 If possible, the intended use of the item should be given on the purchase order especially when the item is ordered for a specifi c end use or uses. NOTE1A typical ordering description is as follows: 10 000 lb, Type 420, annealed, round-cornered square billets, ASTM A 314 dated for valve parts. 4. Manufacture 4.1 Annealing 4.1.1 Blooms and billets of the 400 series of stainless steel types which are highly hardenable, such as Types 414, 420, 431, 440A, 440B, and 440C, are commonly annealed prior to shipment and so specifi ed in order to avoid the possibility of thermal cracking. Those grades are not normally furnished in the as-rolled or as-forged condition. Other hardenable grades, such as Types 403, 410, 416, and 416 Se, which may also require annealing, depending on their composition and size, are furnished suitable for cold cutting when so specifi ed on the purchase order. 4.2 Conditioning 4.2.1 Material may be conditioned by chipping or grinding to remove injurious surface defects provided the depth of conditioning does not exceed that which will affect the surface condition or dimensions of the article to be forged from the bar or billet. 5. Chemical Composition 5.1 The steel shall conform to the chemical composition prescribed in Table 1 for the respective grades. 5.2 Methods and practices relating to chemical analysis required by this specifi cation shall be in accordance with Test Methods, Practices, and Terminology A 751. 6. Dimensions 6.1 Billets and bars shall conform to the shape and dimen- sions specifi ed by the purchaser within a permissible variation of 65 %. 1 This specifi cation is under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel, and RelatedAlloys, and is the direct responsibility of Subcommittee A01.17 on Flat Stainless Steel Products.

General Requirements 7.1 In addition to the requirements of this specifi cation, all requirements of the current edition of Specifi cation A 484/ A 484M shall apply. Failure to comply with the general requirements of Specifi cation A 484/A 484M constitutes non- conformance with this specifi cation. 8.
