摘要
A) the invention relates to a process for the manufacture of parts machined from the martensitic chrome steel to 9 - 12%, that is suitable for the treatment of quenching and tempering. & br / b), characterized in that: & br / d) the steps a) and (b) are carried out with a degree of cold forming epsilon, and to an annealing temperature of ageing such that: & br / d1) or the degree of cold forming a maximum epsilonm appearing in step a) is greater than the critical degree of cold forming the recrystallization of the annealing temperature, & br / d2) or the degree of cold forming a minimum epsilonm i n appearing in step a) is greater than the critical degree of cold forming the recrystallization of the annealing temperature of treatment. br / c) the invention relates to a process for the manufacture of parts machined from the martensitic chrome steel to 9 - 12%, that is suitable for the treatment of quenching and tempering.
