4145H ndi chitsulo chokonzedwa bwino chomwe chimagwiritsidwa ntchito popanga ndi kugwiritsa ntchito zida zobowolera mafuta. Chitsulocho chimakonzedwa mu ng'anjo ya arc ndikukonzedwa kudzera muukadaulo woyenga mofewa. Kuphatikiza apo, zobowola mafuta nthawi zambiri zimagwiritsidwa ntchito kuti zibowola ziwonjezeke. Mukamagwiritsa ntchito zitsulo za 4145H m'zitsime zowongolera, ndizotheka kubowola pang'onopang'ono komanso kuthamanga kwambiri, potero kuchepetsa kuvala ndi kuwonongeka kwa zipilala zobowola.
Chifukwa cha chitsulo chaching'ono chachitsulo cha 4145H ndi malo ang'onoang'ono okhudzana ndi bowo lobowola, zimakhala zovuta kupanga khadi losiyana. Khalidweli limapangitsa chitsulo cha 4145H kukhala chodalirika pobowola, ndikuchepetsa kukangana ndi chitsime komanso kutayika kosafunikira.
Kapangidwe kake kachitsulo ka 4145H ndiyenso chinsinsi chakuchita bwino kwake. Chiŵerengero choyenera cha mankhwala chimatha kuonetsetsa kuti zitsulo zikuyenda bwino m'madera ovuta monga kutentha ndi kuthamanga kwambiri. Kawirikawiri, mankhwala a zitsulo za 4145H amaphatikizapo zinthu monga carbon (C), silicon (Si), manganese (Mn), phosphorous (P), sulfure (S), chromium (Cr), ndi faifi tambala (Ni). Zomwe zili ndi chiŵerengero cha zinthuzi zikhoza kusinthidwa malinga ndi zosowa zenizeni kuti zikwaniritse zofunikira za zochitika zosiyanasiyana zogwiritsira ntchito.
Monga mkulu-mphamvu aloyi chitsulo, chimagwiritsidwa ntchito popanga forgings ndipo ali ubwino zotsatirazi:
Mphamvu yayikulu: 4145H ili ndi mphamvu zokolola zambiri komanso mphamvu zolimba, zomwe zimalola kuti ma forgings azitha kupirira zolemetsa zazikulu komanso zovuta. Izi zimapangitsa kukhala chisankho choyenera kwa mapulogalamu omwe amafunikira zida zamphamvu kwambiri. Kukana kwabwino kwa kuvala: Chifukwa cha kuwonjezera kwa zinthu za alloying, 4145H ili ndi kukana kwabwino kwa kuvala ndipo imatha kukana zotsatira za kuvala, particles abrasive, ndi mikangano. Izi zimapangitsa kuti zinthuzo zikhale zoyenera kwambiri pamapangidwe omwe amagwiritsidwa ntchito pamakangano akulu komanso malo ovala. Kulimba kwabwino: 4145H ili ndi kulimba kwamphamvu kwambiri ndipo imatha kusunga mawonekedwe okhazikika ndi magwiridwe antchito pansi pa kugwedezeka kapena kugwedezeka. Izi zimathandiza forgings kugwira ntchito pansi pa zinthu zovuta ndipo ali ndi chitetezo mkulu. Zosavuta kukonza: Ngakhale 4145H ndi chitsulo champhamvu champhamvu kwambiri, imakhalabe ndi zinthu zabwino zopangira. Ikhoza kupangidwa ndi kukonzedwa kudzera mu njira monga kupangira, kutentha kutentha, ndi makina opangira makina kuti akwaniritse zofunikira za maonekedwe ndi makulidwe osiyanasiyana. Kukana kwa dzimbiri: 4145H imakhala ndi kukana kwa dzimbiri, makamaka m'malo otentha komanso chinyezi. Izi zimathandizira kuti ma forgings azikhala okhazikika m'malo ovuta komanso owonjezera moyo wawo wautumiki.
Mwachidule, kugwiritsa ntchito chitsulo cha 4145H mu zida zobowolera mafuta ndikofunikira kwambiri. Kukonzekera kwake kwa ng'anjo ya arc ndi ukadaulo woyenga mofewa kumapereka zida zabwino zamakina komanso kulimba. Chiŵerengero choyenera cha mankhwala ake chimapangitsa kuti ntchito ikhale yokhazikika pansi pa zovuta zogwirira ntchito. Kupyolera mu kafukufuku wowonjezereka ndi kugwiritsa ntchito luso lamakono, tikhoza kuyembekezera kuti chitsulo cha 4145H chidzagwira ntchito yaikulu m'tsogolomu pobowola chitsime cha mafuta, kukonza bwino pobowola komanso kuchepetsa ndalama.
