Modification of steel structure and schedule of drawing for quality improvement of CuttySharp wires

摘要

This study investigates quality improvement of 88MnCrW5 alloy steel through modification of heat treatment parameters for the rod and drawing schedule for the final wire. Two variants of drawing in nine passes were used to find their effect on surface quality. The first involved dry drawing in the first five passes and wet in the last four, and the second included application of a double die in the final pass.Wire with bright and shining surface quality was achieved with both methods.
