【英文标准名称】: Standard Specification for Steel Castings, Iron-Chromium and Iron-Chromium-Nickel, Heat Resistant, for General Application 【原文标准名称】: 一般用耐热铬铁与镍铬铁合金钢铸件的标准规范 【标准号】: ASTM A297/A297M-2007 【标准状态】: 现行 【国别】: 美国 【发布日期】: 2007 【实施或试行日期】: 【发布单位】: 美国材料与试验协会(US-ASTM)【起草单位】: 【标准类型】: (Specification)【标准水平】: ()【中文主题词】: 【英文主题词】: steel castings; stainless steel heat resistant steel; austenitic stainless steel;【摘要】: 1.1 This specification covers iron-chromium and iron-chromium-nickel alloy castings for heat-resistant service. The grades covered by this specification are general purpose alloys and no attempt has been made to include heat-resisting alloys used for special production application.Note 1&8212;For heat-resisting alloys used for special product application, reference should be made to Specification A 351/A 351M, A 217/A 217M, and A 447/A 447M.1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.【中国标准分类号】: J31【国际标准分类号】: 77_140_80【页数】: 4P.;A4【正文语种】: 英语 作者: 草地飞龙 时间: 2012-12-10 11:10:18
