2、f revision, the year of last revision. A number 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 specification2covers 7, 8, and 9 % nickel alloysteel plates for use in the water quenche
3、d and temperedcondition intended for the fabrication of welded pressurevessels.1.2 Material under this specification is available in threetypes having different chemical composition as follows:Type Nominal Nickel Content, %I9II 8III 71.3 Plates produced under this specification are subject toimpact
4、testing at 320F 195C for Type I or Type III, and275F 170C for Type II; or at such other temperatures asare agreed upon.1.4 The maximum thickness of plates is limited only by thecapacity of the material to meet the specified mechanicalproperty requirements; however, current mill practice normallylimi
5、ts this material to 2 in. 50 mm max.1.5 This material is susceptible to magnetization. Use ofmagnets in handling after heat treatment should be avoided ifresidual magnetism would be detrimental to subsequent fabri-cation or service.1.6 The values stated in either inch-pound units or SI unitsare to b

The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.1
7、.7 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.
