                   【英文标准名称】:     Standard Specification for  Carbon and Alloy Steel Externally Threaded Metric Fasteners            【原文标准名称】:     碳素和合金钢外螺纹米制紧固件用标准规范            【标准号】:     ASTM F568M-2007            【标准状态】:     现行            【国别】:                 【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】: F16.02【标准类型】: (Specification)【标准水平】: ()【中文主题词】: 合金钢;螺栓;碳素钢;紧固件;高碳钢;米制的;质量要求;钢【英文主题词】: alloy steel;  bolts;  carbon steel;  metric;  screws;  steel; structural;  weathering steel;  Alloy steel bolting materials specifications; Carbon steel bolting materials specifications; Externally threaded articles/fasteners/rods; Fasteners (metal) speci【摘要】: 1.1 This specification covers chemical and mechanical requirements for nine property classes of carbon and alloy steel externally  threaded metric fasteners in nominal thread diameters M1.6 through M100  suited  for use in general engineering applications.  1.2 This specification does not cover dimensional requirements for fasteners of any property class. When referencing this specification for  procurement purposes, it is mandatory that size, type, style, and any special  dimensions of the product be additionally specified.  1.2.1 In case of any conflict in requirements, the requirements of the individual product specification shall take precedence over those of  this general specification.  1.2.2 The purchaser may specify additional requirements which do not negate any of the provisions of this general specification or  of the individual product specification. Such additional requirements, the  acceptance of which are subject to negotiation with the supplier, must be  included in the order information (see Section 3).  1.3 Requirements for seven of the nine property classes, 4.6, 4.8, 5.8, 8.8, 9.8, 10.9, and 12.9, are essentially identical with requirements  given for these classes in ISO 898-1. The other two, 8.8.3 and 10.9.3, are  not recognized in ISO standards.  1.4 Classes 8.8.3 and 10.9.3 bolts, screws, and studs have atmospheric corrosion resistance and weathering characteristics comparable  to those of the steels covered in Specification A 588/A 588M.  The atmospheric corrosion resistance of these steels is substantially better  than that of carbon steel with or without copper addition. See 5.2.  When properly exposed to the atmosphere, these steels can be used bare (uncoated)  for many applications.  1.5 When agreed on by the purchaser, Class 5.8 fasteners may be supplied when either Classes 4.6 or 4.8 are ordered; Class 4.8 may  be supplied when Class 4.6 is ordered; Class 8.8.3 may be supplied when Class  8.8 is ordered; and Class 10.9.3 may be supplied when Class 10.9 is ordered.   1.6 The product size range for which each property class is applicable is given in Table 1 and Table 2  on chemical composition requirements, and the mechanical requirements table  (see Table 3).  1.7 Appendix X1 gives conversion guidance to assist designers and purchasers in the selection of a suitable property  class.  1.8 Appendix X2 explains the significance of the property class designation numerals. 【中国标准分类号】: J13【国际标准分类号】: 21_060_10【页数】: 9P.;A4【正文语种】:
