Designation:A312/A312M–09Used in USDOE-NE standards Standard Specification forSeamless,Welded,and Heavily Cold Worked AusteniticStainless Steel Pipes1This standard is issued under thefixed designation A312/A312M;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.This standard has been approved for use by agencies of the Department of Defense.1.Scope*1.1This specification2covers seamless,straight-seam welded,and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.N OTE1—When the impact test criterion for a low-temperature service would be15ft·lbf[20J]energy absorption or15mils[0.38mm]lateral expansion,some of the austenitic stainless steel grades covered by this specification are accepted by certain pressure vessel or piping codes without the necessity of making the actual test.For example,Grades TP304,TP304L,and TP347are accepted by the ASME Pressure Vessel Code,Section VIII Division1,and by the Chemical Plant and Refinery Piping Code,ANSI B31.3,for service at temperatures as low as−425°F [−250°C]without qualification by impact tests.Other AISI stainless steel grades are usually accepted for service temperatures as low as−325°F [−200°C]without impact testing.Impact testing may,under certain circumstances,be required.For example,materials with chromium or nickel content outside the AISI ranges,and for material with carbon content exceeding0.10%,are required to be impact tested under the rules of ASME Section VIII Division1when service temperatures are lower than−50°F[−45°C].1.2Grades TP304H,TP309H,TP309HCb,TP310H, TP310HCb,TP316H,TP321H,TP347H,and TP348H are modifications of Grades TP304,TP309Cb,TP309S,TP310Cb, TP310S,TP316,TP321,TP347,and TP348,and are intended for service at temperatures where creep and stress rupture properties are important.1.3Optional supplementary requirements are provided for pipe where a greater degree of testing is desired.These supplementary requirements call for additional tests to be made and,when desired,it is permitted to specify in the order one or more of these supplementary requirements.1.4Table X1.1lists the standardized dimensions of welded and seamless stainless steel pipe as shown in ANSI B36.19. These dimensions are also applicable to heavily cold worked pipe.Pipe having other dimensions is permitted to be ordered and furnished provided such pipe complies with all other requirements of this specification.1.5Grades TP321and TP321H have lower strength require-ments for pipe manufactured by the seamless process in nominal wall thicknesses greater than3⁄8in.[9.5mm].1.6The values stated in either SI units or inch-pound units are to be regarded separately as standard.Within the text,the SI units are shown in brackets.The values stated in each system may not be exact equivalents;therefore,each system shall be used independently of the bining values from the two systems may result in non-conformance with the standard.The inch-pound units shall apply unless the“M”designation of this specification is specified in the order.N OTE2—The dimensionless designator NPS(nominal pipe size)has been substituted in this standard for such traditional terms as“nominal diameter,”“size,”and“nominal size.”2.Referenced Documents2.1ASTM Standards:3A262Practices for Detecting Susceptibility to Intergranu-lar Attack in Austenitic Stainless SteelsA370Test Methods and Definitions for Mechanical Testing of Steel ProductsA941Terminology Relating to Steel,Stainless Steel,Re-lated Alloys,and FerroalloysA999/A999M Specification for General Requirements for Alloy and Stainless Steel PipeA1016/A1016M Specification for General Requirements for Ferritic Alloy Steel,Austenitic Alloy Steel,and Stain-less Steel TubesE112Test Methods for Determining Average Grain Size E381Method of Macroetch Testing Steel Bars,Billets, Blooms,and ForgingsE527Practice for Numbering Metals and Alloys in the Unified Numbering System(UNS)1This specification is under the jurisdiction of ASTM Committee A01on Steel,Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.10on Stainless and Alloy Steel Tubular Products.Current edition approved May15,2009.Published June2009.Originally approved st previous edition approved in2008as A312/A312M–08a.2For ASME Boiler and Pressure Vessel Code applications see related Specifi-cation SA-312in Section II of that Code.3For referenced ASTM standards,visit the ASTM website,,or contact ASTM Customer Service at service@.For Annual Book of ASTM Standards volume information,refer to the standard’s Document Summary page on the ASTM website.*A Summary of Changes section appears at the end of this standard.

ASME SA789 SUNLAKE表1化学成分除非规定范围和最小值，上数值为最大值。
表中出现（..）时，不定义最小值和成分分析。
B根据ASTM E527和SAE J1086实用规程，建立了新的UNS标号。
表2 热处理制度、拉伸性能、硬度参数表A机械性能不适用于外径＜1/8in（3.2mm）或壁厚＜0.015in（0.4mm）的管子。
ASME SA789 SUNLAKE 尺寸要求：1、外径、壁厚和长度尺寸允许偏差见下表：A 订货的管子当壁厚大于等于3/4in.(19mm)，或内径小于等于60%外径时，要求在壁厚是上有较宽的偏差范围，在这种规格中允许有±12.5%的壁厚偏差。
对于外径小于1/2in.(12.7mm)，由于轧制时芯子不能顺利地拔出，故壁厚可以在规定值的±15%内变化。
