摘要：
The paper presents the results of investigation of the inhomogeneity of mechanical properties in the 1H18N9T stainless steel rods. Sixteen drawing schedules of reduction ratios varying from 5.5% to 24.4% and die angles varying from 6-degrees to 20-degrees were examined. Local values of R0.2, R(m) and A100 were determined from the tension tests carried on the mini-specimens. Distribution of the HV5 hardness on the transverse and longitudinal cross sections were evaluated. Experimentally found coefficient allows to determine the 0.2% of set stress and tensile strength from the hardness measurements.
