ASTM A1040:17 pdf download.Standard Guide for Specifying Harmonized Standard Grade Compositions for Wrought Carbon, Low-Alloy, and Alloy Steels.
3. 1. 1. 1 Discussion—Product forms such as “C” shapes, ‘HP” shapes, “L” shapes, “M” shapes, ‘MC” shapes, ‘S” shapes. ‘W” shapes, and sheet piling are considered long products. Such product forms are produced to mechanical properties and arc not normally produced to the chemical compositions listed in this guide.
3.1.2 flat pivduct, n—generic term describing wrought sheet and strip.
3.2 Refer to Terminology A94 I for additional definitions of terms used in this guide.
4. Significance and Use
4. 1 It is anticipated that the ASTM Subcommittees AOl .02, A01.03. AO1.06, AO1.09, AOl.! 1, A01.15, A0l.19,A0l.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.
4.2 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.
5. General Guidelines Used for Determining Composition I inhlts
5.1 Table I gives typical chemical composition limits for respective elements.
