Chemical Composition5.1 The cast or heat (formerly ladle) analysis of the steelshall conform to the chemical requirements s
16、hown in Table 1,or chemical compositions can be specified from carbon 0.16 %maximum to 0.25 % maximum, inclusive, and manganese0.90 % maximum, inclusive, which conforms to the standardchemical ranges and limits tables in the Appendix of Specifi-cation A 568/A 568M.5.1.1 Unspecified elements may be p
17、resent. Limits on ele-ments shall be as stated in Table 2.5.1.1.1 Each of the elements listed in Table 2 shall beincluded in the report of the heat analysis. When the amount ofcopper, nickel, chromium, or molybdenum is less than 0.02 %,the analysis may be reported as 0.02 %. When the amount ofvanadi
18、um or columbium is less than 0.008 %, the analysis maybe reported as 0.008 %.5.2 Where material is used for fabrication by welding, caremust be exercised in selection of the chemical composition toassure compatibility with the welding process and its effects onaltering the properties of the steel.6.
19、 Bending Properties6.1 The minimum forming radius (radii) which steel cov-ered by this specification can be expected to sustain is listed inthe appendix and is discussed in more detail in SpecificationsA 568/A 568M and A 749/A 749M. When tighter bend radiiare required, or curved or offset bends are
20、involved, or whenstretching or drawing are also a consideration, the producersshall be consulted.7.
