METHOD OF MANUFACTURE OF ARMOR ELEMENTS FOR INDIVIDUAL PROTECTIVE MEANS Russian patent published in 1994 - IPC

FIELD: individual protective means. SUBSTANCE: the method consists in hot rolling, cooling, annealing, mechanical treatment, cold forming, quenching, tempering. Rolling is accomplished within a temperature range from Ac₃ to Az₃ with partial reductions within 12 to 14%. Annealing is carried out with utilization of rolling heat, quenching - at a rate of cooling within 40 to 50 C, and tempering - at a temperature of 140 to 170 C. EFFECT: facilitated procedure.
