                   【英文标准名称】:     Standard Guide for Specifying Harmonized Standard Grade Compositions for Wrought Carbon, Low-Alloy, and Alloy Steels            【原文标准名称】:     规范锻造碳素钢、低合金钢、合金钢统一的标准等级组分的标准指南            【标准号】:     ASTM A1040-2007            【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】: A01.97【标准类型】: (Guide)【标准水平】: ()【中文主题词】: 合金钢;碳;组分;统一的;可锻合金【英文主题词】: alloy steels;carbon steels;harmonized carbon, low-alloy, and alloy steel compositions;low-alloy steels【摘要】: It is anticipated that the ASTM Subcommittees A01.02, A01.03, A01.06, A01.09, A01.11, A01.15, A01.19, A01.22, and A01.28 will use the standard composition limits listed in this guide for the grades identified in their product specifications unless there is a specific technical justification for doing otherwise. The composition limits given in this guide are to be used as guides in determining limits for each of the elements included in the total composition of each grade. The composition limits have been established with the intent that each ASTM subcommittee will find it necessary to require only a minimum number of changes to reflect specific technical effects. Section 5 lists the general guidelines followed for determining the limits for each element; the limits established in this guide are based upon these guidelines. TABLE 1 Expression of Chemical Composition Limits  Chemical ElementChemical Composition Limit C, Cr, Cu, Mn, Mo, Ni, Pb, SiTwo decimal places (0.xx % ) or (1.xx %) Al, Ca, N, Nb (Cb), P, S, Sn, Ti, VThree decimal places (0.xxx %) BFour decimal places (0.xxxx %)
