摘要： A method of making a small diameter elongated steel article such as wire or strip is disclosed. The method includes the step of melting a steel alloy having the following weight percent composition C0.88-1.00 Mn0.20-0.80 Si0.50max. P0.050max. S0.010-0.100 Cr0.15-0.90 Ni0.10-0.50 Mo0.25max. Cu0.08-0.23 V0.025-0.15  N0.060max. O0.040max. and the balance is iron and usual impurities. The method includes melting the alloy, atomizing the molten alloy to make a pre-alloyed metal powder, consolidating the metal powder to substantially full density, and then hot working the consolidated metal powder to form an intermediate elongated article. The method further includes a multi-step heat treating process. A small diameter, elongated steel article having enhanced machinability is also disclosed.
