In order to estimate mechanical properties of high tension steels for machine tools: Cr-Mo steel, Ni steel, Ni-Cr steel and Ni-Cr-Mo steel, we applied property prediction by a perceptron type neural network. It was found that six mechanical properties: yield point, tensile strength, diaphragm, impulsive force and hardness are predictable within experimental error, almost 20%, using only the amount of C, Mn, Ni, Cr and Mo in the steels.

Keywords: Yield Point, Tensile Strength, Elongation Percentage, Diaphragm, Impulsive Force, Hardness, Cr-Mo Steel, Ni Steel, Ni-Cr Steel, Ni-Cr-Mo Steel, Property Estimation, Neural Network
