FIELD: technological processes, metal processing.
SUBSTANCE: invention concerns engineering industry and can be applied in various industry spheres for thermal processing of maraging steel articles, such as "08Х15Н5Д2Т", "06Х14Н6Д2МБТ", "10Х14Н4АМ3" and "07Х16Н6". To enhance resilience an article is annealed at 650-670°C for 6-10 hours, further is heated to 1000-1070°C for tempering in furnace, matured for 2-3 hours and cooled down in oven to 880- 900°C first, with maturing at that temperature for 2.5-3 hours, then cooled down in water, blazed off and aged.
EFFECT: enhanced resilience.
