1、Designation: A314 19Standard Specification forStainless Steel Billets and Bars for Forging1This standard is issued under the fixed designation A314; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A numbe

2、r in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification covers stainless steel billets and

3、 barsintended only for forging.1.2 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Or

Ordering Information3.1 It is the responsibility of the purchaser to specify allrequirements that are necessary for material ordered under thisspecificatio

6、n. Such requirements may include but are notlimited 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, and soforth),3.1.5 Form: bar or forging billet,3.1.6 Applicabl

7、e dimensions, including size, thickness,width, and length,3.1.7 ASTM designation and date of issue,3.1.8 Preparation for delivery (see Specification A484/A484M),3.1.9 Marking (see Specification A484/A484M), and3.1.10 Exceptions to the specification or special require-ments.3.2 If possible, the inten

8、ded use of the item should be givenon the purchase order especially when the item is ordered fora specific end use or uses.NOTE 1A typical ordering description is as follows: 10 000 lb, Type420, annealed, round-cornered square billets, ASTM A314 datedfor valve parts.4. Manufacture4.1 AnnealingBlooms

9、 and billets of the 400 series ofstainless steel types which are highly hardenable, such as Types414, 420, 431, 440A, 440B, and 440C, are commonly annealedprior to shipment and so specified in order to avoid thepossibility of thermal cracking. Those grades are not normallyfurnished in the as-rolled

10、or as-forged condition. Other hard-enable grades, such as Types 403, 410, 416, and 416 Se, whichmay also require annealing, depending on their compositionand size, are furnished suitable for cold cutting when sospecified on the purchase order.4.2 ConditioningMaterial may be conditioned by chip-ping

11、or grinding to remove injurious surface defects providedthe depth of conditioning does not exceed that which will affectthe surface condition or dimensions of the article to be forgedfrom the bar or billet.5. Chemical Composition5.1 The steel shall conform to the chemical compositionprescribed in Ta
