Description

Przedmiotem wynalazku jest stal na lancuchy górnicze.
Znana jest stal przeznaczona do 'produkcji lan¬ cuchów górniczych z normy ZN-70/0644-04 z ozna¬ czeniem G25HGNMA o nastepujacym skladzie che¬ micznym w stosunku wagowym C ' = 0^22-^),29t%, Mn -i 1,00^1,30%, Si =; 0,17—0,37%, P max=0,030%, S max =10,030%, Cr = 0,45—0,05%, Ni = 0,45— —0,65%, Mo = 0,20—0,30%, Al min = 0,02%, Cu max =,0,20%, reszta zelazo i nieuniknione zanie¬ czyszczenia.
Istota wynalazku jest stal na lancuchy górnicze o nastepujacym skladzie chemicznym w stosunku wagowym C = 0,13—0,10%, Mn = 1,8-^2,20%, Si = = 0,17—0,37%, P max = 0,025%, S max = 0,025%, Cr =; 1,16—11,45%, Ni = 1,00^1,30%, Nto = okolo 0,03%, Mo; = 0,15—0,25%, Cu =( 0,4(^-^0^0%, reszta zelazo i nieuniknione zanieczyszczenia.
Przykladem wykonania wynalazku jest staj na lancuchy górnicze o skladzie chemicznym w sto¬ sunku wagowym C=^0,15%, Mn = 2,00%, Si = = 0,30%, Cr = 1,30%, Ni = ly20%, Nb =10,03%, Mo = 0^20%, Cu =:0,50%, P = 0,020%, S=r0,018%, reszta zelazo i nieuniknione zanieczyszczenia.
Stal o takim skladzie chemicznym posiada dofbre wlasnosci zgrzewalne, oraz wysokie naprezenia zry¬ wajace do 80 feGi/mm2. Lancuchy wykonane z tej stali posiadaja dluzsza zywotnosc, a wydluzenie calkowite przy zarzeniu wynosi 7%.
