8、 alloying effect; when thespecified minimum for copper does not exceed 0.40 %; orwhen the maximum content specified for any of the followingelements does not exceed these percentages: manganese 1.65,silicon 0.60, or copper 0.60.3.1.1.1 Discussion In all carbon steels small quantities ofcertain unspe
9、cified and unrequired residual elements (such ascopper, nickel, molybdenum, chromium, etc.) unavoidablyretained from raw materials are sometimes found. Theseelements are considered as incidental and are not normallydetermined or reported.Elements (such as sulfur and lead) may be specified to improve

16、lly the tensilestrength. The straightening operation may also induce changesin the diameter of the wire. The extent of the changes in theproperties of the wire after cold straightening depends upon thekind of wire and also on the normal variation in the adjust-ments of the straightening equipment. I
17、t is therefore notpossible to forecast the properties of straightened and cut wire.Each kind of wire needs individual consideration. In mostcases, the application of straightened and cut wire is notseriously influenced by these changes.3.1.4 wire rodsrods that are hot rolled from billets to anapprox
