2、,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 quenched and temperedcondi
3、tion intended for the fabrication of welded pressurevessels.1.2 Material under this specification is available in threetypes having different chemical composition as follows:TypeNominal Nickel Content,%I9II8III71.3 Plates produced under this specification are subject toimpact testing at 320F 195C fo
4、r 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 normallylimits this material to 2 in.50
5、 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 be regarded separately as stan
