The mathematical modeling of expanding process of tubular piece made of 12X18H10T in cold condition by conical punch was carried out by finite element method. The influence of cone’s angle of punch at the load of expanding, the stress-strain state and the resource usage of metal plasticity of deformed metal before loss of stability of geometric form were determined. The final form and dimensions of deformed workpiece’s part, coefficients of expanding and metal strengthening were determined.
