Abstract

PURPOSE:To perform tension straightening in a condition resembling to stress- strain characteristics of ordinary steel in cold state and prevent hardening of the material when pulling in the titled method of sintered hard strip especially high-grade strip by performing the tension straightening in a specified range of temperature. CONSTITUTION:Sintered hard strip material, especially high grade strip material is straightened by tension at a temperature range of 600-1,200 deg.C. By this way, steep slope of stress-strain diagram of sintered hard steel becomes remarkably flat under the influence of high temperature, and stress-strain characteristics resembling to ordinary steel in cold state can be obtained for this sintered hard steel. Further, this method has merit of preventing occurrence of material hardening when the strip is pulled at a high temperature.
