Abstract
Przedmiotem wynalazku jest stal wielofazowa, przeznaczona zwłaszcza na szyny normalnotorowe, której głównym składnikiem strukturalnym jest bezwęglikowy ferryt bainityczny i związany z nim austenit resztkowy, a także ferryt allotrimorficzny, martenzyt samo - odpuszczony, charakteryzująca się tym, że zawartość ferrytu bainitycznego jest powyżej 70% obj. stali, ferrytu allotrimorficznego poniżej 10% obj. stali, martenzytu samo – odpuszczonego poniżej 10% obj. stali, austenitu resztkowego związanego z ferrytem bainitycznym - o zawartości węgla min. 1.25% mas. - powyżej 10% obj. stali. Ponadto ferryt bainityczny umacniany jest nano - cząstkami węglika TiC, a zawartość podstawowych pierwiastków w stali jest nie mniejsza niż: C - 0.15% mas., Si - 0.60% mas., Mn - 1.20% mas., Cr - 1.20% mas., Ni - 0.20% mas., Mo - 0.10% mas., a ponadto zawiera ona: Ti - 0.01 - 0.25% mas., przy spełnieniu zależności (% mas. Mo)/(%mas. Ti) > 1; Al - 0.01 - 0.80% mas; B - 0.001 - 0.003% mas., H2 ≤ 2 ppm, N ≤ 80 ppm, przy czym ilość poszczególnych składników jest w stosunku całkowitej masy stali wielofazowej.
