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.

摘要： A small diameter, elongated steel article, comprising fully consolidated, prealloyed metal powder is disclosed. The consolidated metal powder has a microstructure that has a substantially uniform distribution of fine grains having a grain size of not larger than about 9 when determined in accordance with ASTM Standard Specification E 112. The microstructure of the consolidated metal powder is further characterized by having a plurality of substantially spheroidal carbides uniformly distributed throughout the consolidated metal powder that are not greater than about 6 microns in major dimension and a plurality of sulfides uniformly distributed throughout the consolidated metal powder wherein the sulfides are not greater than about 2 microns in major dimension. A process for making the elongated steel article is also disclosed.
