Designation:A836/A836M14Standard Specification forTitanium-Stabilized Carbon Steel Forgings for Glass-LinedPiping and Pressure Vessel Service1This standard is issued under the fixed designation A836/A836M;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 reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers nonstandard as-forged fittings,valve components,and parts for glass-lined piping and pres-sure vessel service.Mechanical properties are certified on thebasis of test material subjected to heat treatments to simulateglass-coating operations.1.2 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 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.The inch-pound units shall apply unless the“M”designation of this specification is specified in the order.2.Referenced Documents2.1 ASTM Standards:2A788/A788M Specification for Steel Forgings,General Re-quirementsA961/A961M Specification for Common Requirements forSteel Flanges,Forged Fittings,Valves,and Parts forPiping Applications3.Ordering Information3.1 Product furnished to this specification shall conform tothe requirements of Specification A961/A961M,including anysupplementary requirements that are indicated in the purchaseorder.Failure to comply with the requirements of SpecificationA961/A961M constitutes non-conformance with this specifi-cation.3.2 It is the purchasers responsibility to specify in thepurchase order all ordering information necessary to purchasethe needed material.Examples of such information include butare not limited to the ordering information in SpecificationA961/A961M and the following:3.2.1 Supplementary requirements,and3.2.2 Additional requirements(see 11.1,13.1,and 13.2).3.3 If the requirements of this specification are in conflictwith the requirements of Specification A961/A961M,therequirements of this specification shall prevail.4.Materials and Manufacture4.1 The material shall be forged by hammering,pressing,rolling,extruding,or upsetting,such that the finished productwill be a forging as defined in the Terminology Section ofSpecification A788/A788M.4.2 When specified in the order,the manufacturer shallsubmit for approval by the purchaser a sketch showing theshape of the rough forging before machining.4.3 Forgings shall be protected against sudden or too rapidcooling from the rolling or forging while passing through thecritical range.4.4 Heat treatment of forgings is neither required norprohibited.However,the test material for qualifying theforging or the welding procedure shall be heat treated tosimulate glass-coating operations.5.Chemical Composition5.1 An analysis of each heat shall be made by the manufac-turer to determine the percentages of the elements specified inTable 1.The chemical composition thus determined shallconform to the requirements in Table 1.6.Mechanical Properties6.1 The test material shall conform to the requirements as totensile properties prescribed in Table 2.7.Number of Tests and Retests7.1 One tension test shall be made from each heat.7.2 If any test specimen is defectively machined,it may bediscarded and another specimen substituted.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.22 on Steel Forgings and Wrought Fittings for Piping Applications and BoltingMaterials for Piping and Special Purpose Applications.Current edition approved Oct.1,2014.Published October 2014.Originallyapproved in 1984.Last previous edition approved in 2013 as A836/A836M 13.DOI:10.1520/A0836_A0836M-14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1Copyright by ASTM Intl(all rights reserved);8.Retests8.1 When one or more representative test specimens do notconformtospecificationrequirementsforthetestedcharacteristic,only a single retest for each nonconformingcharacteristic may be performed to establish product accept-ability.Retests shall be performed on twice the number ofrepresentative specimens that were originally nonconforming.When any retest specimen does not conform to specificationrequirements for the characteristic in question,the lot repre-sented by that specimen shall be rejecte
