Input (Czech): Zpusob tepelného zpracování soucástí z korozivzdorné martenzitické oceli X12Cr13, zejména cepu nájezdu pro autozámek, pri kterém je soucást nejprve kalena a potom popoustena spocívá v tom, ze za prítomnosti dusíku se behem 30 minut provede ohrev na teplotu 600 .degree.C s následnou prodlevou 20 minut na této teplote, poté po odcerpání dusíku se vevakuu behem 30 minut provede ohrev na teplotu 850.degree.C s následnou prodlevou 30 minut na této teplote a behem 20 následujících minut se provede ohrev na kalicí teplotu 930 az 1040 .degree.C, na níz se za prítomnosti dusíku setrvá 60 minut, potom následuje ponor do kapaliny s rychlým snízením teploty na 40 .degree.C a na vzduchu se nejprve na této teplote setrvá 90 minut, poté se behem 60 minut provede ohrev na popoustecí teplotu 250 az 260 .degree.C, na té se setrvá 240 minut a následuje volné ochlazení na teplotu prostredí.
Output (English): In the present invention, there is disclosed a heat treatment process of parts made of X12Cr13 corrosion resistant steel, in particular a pin of a car lock entering surface, in which first the part is hardened and then tempered, wherein the process is characterized in that heating to a temperature of 600 degC is carried out in the presence of nitrogen and in the period of 30 minutes with subsequent dwell for a period of 20 minutes in this temperature, then, after evacuating nitrogen, heating is carried out in vacuum and within 30 minutes to a temperature of 850 degC with subsequent dwell of 30 minutes in this temperature and during the subsequent 20 minutes heating to hardening temperature within the range of 930 to 1040 degC is carried out with a dwell in this hardening temperature of 60 minutes in the presence of nitrogen. Subsequently the part is immersed into a liquid to reduce abruptly temperature to 40 degC and then the part is let in this temperature in air for a period of 90 minutes. Then, heating is carried out during 60 minutes period to a tempering temperature within the range of 250 to 260 degC with a dwell of 240 minutes in this temperature and in the end, a slow air-cooling to ambient temperature follows.
