45 # sheet eshushu esongwayo

Inkqubo yonyango yokushisa ephakanyisiweyo kwi-45 yensimbi echazwe kumgangatho we-GB / T699-1999 iqhelekile kwi-850 ° C, ukucima kwi-840 ° C, kunye nokufudumala kwi-600 ° C. Ukusebenza okuphunyeziweyo ngamandla esivuno ≥355MPa
Umgangatho we-GB / T699-1999 uchaza ukuba amandla okuqina ensimbi ye-45 yi-600MPa, amandla okuvelisa yi-355MPa, izinga lokunyusa li-16%, kunye nokunciphisa indawo yi-40%.
Isicelo
No. 45 intsimbi isetyenziswa ngokubanzi koomatshini, xa ingaphathwa ubushushu: HB≤229; unyango lobushushu: normalizing; amandla empembelelo: Aku≥39J; amandla aphezulu, iplastiki elungileyo kunye nokuqina, i-45 # ipleyiti yentsimbi emva kokucima ngaphandle kokufudumala, ubunzima bukhulu kune-HRC55 (Ukuya kwi-HRC62) ifanelekile. Emva kokunyangwa kobushushu kunye nobushushu, inokufikelela kwi-HRC42-46, engenakuqinisekisa kuphela iimpawu zayo ezintle zoomatshini, kodwa iphinde ifumane iimfuno zobunzima bomphezulu. Isetyenziselwa ukwenza izilungiso zecandelo elincinci elinokumelana nemithwalo emikhulu. Amalungu asemgangathweni kunye neendawo ezinkulu eziqhelekileyo ezinoxinzelelo oluncinci, kunye neendawo ezinobunzima obungadingi amandla aphezulu aphezulu, njengeengcebiso, izithuba zesikhokelo, izandla zokubukela kunye namanye amacandelo.
