摘要

P a) The invention relates to a process for manufacturing machined parts from 9-12% martensitic chromium steel, suitable for quenching and tempering treatment. BR/ b) characterized in that: BR/ d) steps a) and b) are carried out with a degree of epsilon cold forming such and at a temperature of annealing such that: BR/ d1) the degree of maximum cold forming epsilonm ax occurring in step a) is greater than the critical degree of cold forming for recrystallization at the annealing temperature, BR/ d2) is the degree of forming Minimum cold epsilonm in appearing in step a) is greater than the critical degree of cold forming for recrystallization at the annealing temperature of income. BR/ c) The invention relates to a process for the manufacture of machined parts from 9-12% martensitic chromium steel, suitable for tempering and tempering treatment. / P
