Description
Przedmiotem wynalazku jest stal bainityczna na ksztaltowniki. Jest to niskostopowa stal spawalna o strukturze bainitycznej osiagajaca po walcowaniu na goraco granice plastycznosci minimum 410 N/mm2(42 kG/mnj2 ) przeznaczona na ksztaltowniki, zwlaszcza do wytwarzania obudów kopalnianych.Dotychczas ksztaltowniki wytwarza sie ze spawalnych stali weglowych zwyklej jakosci osiagajacych granice plastycznosci minimum 235^255 N/mm2 (24 -^ 26 kG/mm2) i ze stali niespawalnych. Na obudowy górnicze stosowana jest niespawalna stal konstrukcyjna weglowa o strukturze ferrytycznoperlitycznej, zawierajaca wagowo okolo 0,35% C; okolo 0,20% Si; max 0,05% P; max 0,05% S z dobierana zawartoscia manganu zalezna o grubosci koncowego wyrobu osiagajaca granice plastycznosci 295 N/mm2(30 kG/mm2 ).Celem wynalazku jest opracowanie niskostopowej stali spawalnej z której ksztaltowniki, po zwyklym walcowaniu na goraco, charakteryzuja sie struktura bainityczna i osiagaja granice plastycznosci powyzej 390 N/mm2 (40 kG/mm2).Stal zawierajaca wagowo 0,10^-0,20% C, 0,20-H),50%HSi, max 0,045% P, max 0,045% S, 0,20'-K),60% Mo, 0,01 t 0,08% Al, 0,00 -H),05% Ti oraz mangan, wanad, bor i zelazo, wedlug wynalazku zawiera wagowo 0,60 -s-1,40% manganu 0,02 -H),l 2% wanadu oraz 0,001 * 0,006 boru.Stal wedlug wynalazku po przeróbce plastycznej na goraco na ksztaltowniki osiaga granice plastycznosci minimum 410 N/mm2 (42 kG/mm2), wydluzenie wzgledne A5 równe minimum 18% i udarnosci na próbkach Mesnagera minimum 80 J/cm2 (8 kGm/cm2) przy temperaturach dodatnich.
