1、Designation:A815/A815M13A815/A815M13a Standard Specication for Wrought Ferritic, Ferritic/Austenitic, and Martensitic Stainless Steel Piping Fittings 1 This standard is issued under the xed designationA815/A815M; the number immediately following the designation indicates the year of original adoptio
2、n or, in the case of revision, the year of last revision.Anumber in parentheses indicates the year of last reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval. 1. Scope* 1.1 This specication covers two general classes, WP and CR, of wrought ferrit
3、ic, ferritic/austenitic, and martensitic stainless steel ttings of seamless and welded construction covered by the latest revision of Specication A960/A960M. Fittings differing from these standards may be furnished in accordance with Supplementary Requirement S58 of Specication A960/A960M. 1.1.1 Cla
4、ss WP ttings are subdivided into four subclasses: Classes WP-S, WP-W, WP-WX, and WP-WU. They are manufactured to the requirements of Specication A960/A960M, and they shall have pressure ratings compatible with 12.2. Class WP-S ttings are those manufactured from seamless product by a seamless method
5、of manufacture (marked with class symbol WP-S); Class WP-W ttings are those which contain welds where the tting fabrication or construction welds have been radiographed (marked with class symbolWP-W); and ClassWP-WX ttings are those which contain welds where all welds have beenradiographed(markedwit

7、n does not apply to cast ttings. 1.3 Optional supplementary requirements are provided. When desired, one or more of these may be specied in the order. 1.4 This specication is expressed in both inch-pound units and in SI units. However, unless the order species the applicable M specication designatio

19、on Requirements and Ordering Information 3.1 Material furnished to this specication shall conform to the requirements of Specication A960/A960M including any supplementary requirements that are indicated in the purchase order. Failure to comply with the common requirements of Specication A960/A960M
20、constitutes nonconformance with this specication. In case of conict between this specication and Specication A960/A960M, this specication shall prevail. 3.2 Specication A960/A960M identies the ordering information that should be complied with when purchasing material to this specication. 4. Material
21、s 4.1 The material for ttings shall consist of forgings, bars, plates, or seamless or welded tubular products that conform to the chemical requirements in Table 1. 4.2 The steel shall be melted by one of the following processes: 4.2.1 Electric furnace (with separate degassing and rening optional), 4
22、.2.2 Vacuum furnace, or 4.2.3 Electric furnace followed by vacuum or electroslag-consumable remelting. 4.3 If secondary melting is employed, the heat shall be dened as all ingots remelted from a primary heat. 5. Manufacture 5.1 FormingForgingorshapingoperationsmaybeperformedbyhammering,pressing,pier
