2、 Parts,Suitable for High-TemperatureService1This standard is issued under the fixed designationA 217/A 217M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last
3、reapproval.A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This specification2covers martensitic stainless steel andalloy steel castings for valves,flanges,fittings
4、,and otherpressure-containing parts(Note 1)intended primarily forhigh-temperature and corrosive service(Note 2).1.2 One grade of martensitic stainless steel and nine gradesof ferritic alloy steel are covered.Selection will depend ondesign and service conditions,mechanical properties,and thehigh-temp
5、erature and corrosion-resistant characteristics(Note3).NOTE1Carbon steel castings for pressure-containing parts are cov-ered by Specification A 216/A 216M.Low alloy quench-and-temperedgrades equivalent to Specification A 217/A 217M grades may be found inboth Specifications A 352/A 352M and A 487/A 4
6、87M.NOTE2The grades covered by this specification represent materialsthat are generally suitable for assembly with other castings or wroughtsteel parts by fusion welding.It is not intended to imply that these gradespossess equal degrees of weldability;therefore,it is the responsibility ofthe purchas
7、er to establish for himself a suitable welding technique.Sincethese grades possess varying degrees of suitability for high-temperatureand corrosion-resistant service,it is also the responsibility of the purchaserto determine which grade shall be furnished,due consideration beinggiven to the requirem
8、ents of the applicable construction codes.NOTE3The committee formulating this specification has includednine grades of materials that are considered to represent basic types offerritic alloy steels suitable for valves,flanges,fittings,and other pressure-containing parts.Additional alloy steels that
9、may better fulfill certain typesof service will be considered for inclusion in this specification by thecommittee as the need becomes apparent.1.3 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard.Within the text,theSI units are shown in brackets.The v
10、alues 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.Inch-pound units are applicable for material ordered toSpecification A 217 and SI units for mate
