Abstract

The quality of a spheroidized annealed wire affects the forming quality of fasteners. In the fastener industry, wire manufacturers use an intercritical process for spheroidized annealing medium carbon steel wires. The influence of intercritical annealing parameters namely section-area reductions, preheating rate, spheroidized annealing temperature, prolonged heating time, holding temperature and time, cooling rate and temperature is investigated for the responses of quality characteristics of wires, such as tensile strength and ductility, after spheroidized annealing operation. A series of experimental tests on SCM435 alloy medium carbon steel wires is carried out in a commercial hydrogen furnace. Taguchi method along with ANOVA is used to obtain optimal spheroidized annealing conditions to improve the mechanical properties of alloy steel wires for cold forming. It is experimentally revealed that the area reduction ratio, spheroidized annealing temperature, holding temperature and cooling temperature significantly affect the quality of annealed SCM435 alloy steel wires. The optimal combination of process parameters lead to obtaining the optimal mean tensile strength of 567.8 MPa and mean ductility of 0.361. A comparison between the results obtained using the optimal spheroidized annealing conditions and the measures determined using the original settings shows that the new spheroidizing parameter settings effectively improve the performance measures over their values at the original settings. The cold formability of SCM435 alloy steel wires is effectively improved.
