ASTM A314-2019 pdf free download.Standard Specification for Stainless Steel Billets and Bars for Forging
1. Scope
1.1 This specification covers stainless steel billets and bars intended 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 the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
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: type or UNS designation (Table 1), 3.1.3 Condition, 3.1.4 Cross section (round, round-cornered square, and so forth), 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 Specification A484/ A484M), 3.1.9 Marking (see Specification A484/A484M), and 3.1.10 Exceptions to the specification 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 specific end use or uses. N OTE 1—A typical ordering description is as follows: 10 000 lb, Type 420, annealed, round-cornered square billets, ASTM A314 dated for valve parts.
4. Manufacture
4.1 Annealing—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 specified in order to avoid the possibility of thermal cracking. Those grades are not normally furnished in the as-rolled or as-forged condition. Other hard- enable 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 specified on the purchase order. 4.2 Conditioning—Material may be conditioned by chip- ping or grinding to remove injurious surface defects provided the depth ofconditioning 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 specification shall be in accordance with Test Methods, Practices, and Terminology A751.
