1、Designation:A94695(Reapproved 2004)Standard Specification forChromium,Chromium-Nickel and Silicon Alloy Steel Plate,Sheet,and Strip for Corrosion and Heat Resisting Service1This standard is issued under the fixed designation A946;the number immediately following the designation indicates the year of
2、original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers alloy steels having a chromiumcontent eq
3、ual to or less than 11.0%in plate,sheet,strip formfor corrosion,and heat-resisting applications.1.2 Some steels covered by this specification,especially thehigh silicon containing steels,because of their particular alloycontent and specialized properties,may require special care intheir fabrication
4、and welding.Specific procedures are offundamental importance,and it is presupposed that all param-eters will be in accordance with approved methods capable ofproducing the desired properties in the finished fabrication.1.3 The values stated in inch-pound units or SI units are tobe regarded separatel
5、y as standard.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.1.4 This specification and the applicable material specifica-tions are expres
6、sed in both inch-pound and SI units.However,unless the order specifies the applicable“M”specificationdesignation(SI units),the material shall be furnished ininch-pound units.2.Referenced Documents2.1 ASTM Standards:2A480/A480M Specification for General Requirements forFlat-Rolled Stainless and Heat-
