Kodi chuma chachitsulo S136 ndi chiyani ndipo makhalidwe ake ndi chiyani?

Chitsulo cha S136 ndi chitsulo chosapanga dzimbiri, chomwe chimatchedwanso 420SS kapena 4Cr13.Ndi ya martensitic zitsulo zosapanga dzimbiri, zomwe zimakhala ndi kukana kwa dzimbiri komanso kuuma kwakukulu, ndipo zimagwiritsidwa ntchito kwambiri popanga nkhungu.

Zotsatirazi ndizofotokozera mwatsatanetsatane za mawonekedwe a S136 die steel kuchokera kuzinthu 7 zotsatirazi:

(1) Chemical zikuchokera: The mankhwala zikuchokera S136 kufa zitsulo makamaka kaboni (C), chromium (Cr), pakachitsulo (Si), manganese (Mn), phosphorous (P), sulfure (S) ndi zinthu zina.Pakati pawo, zomwe zili ndi chromium zambiri zimapereka kukana kwa dzimbiri komanso kukana kwa okosijeni.

(2) Kukana kwa dzimbiri: Chitsulo cha S136 chimakhala ndi kukana bwino kwa dzimbiri ndipo chitha kugwiritsidwa ntchito kwa nthawi yayitali m'malo achinyezi opanda dzimbiri.Izi zimapangitsa kuti zikhale zoyenera kupanga nkhungu zomwe zimafunikira kukhudzana ndi chinyezi, asidi ndi maziko, ndi zina zotero.

(3) Kuuma kwakukulu: S136 kufa zitsulo kumatha kufika pamtunda wouma kwambiri pambuyo pa chithandizo choyenera cha kutentha.Kuuma nthawi zambiri kumakhala mu HRC 48-52 ndipo kumatha kuonjezedwa ndi kutentha kwina.Izi zimapangitsa S136 kufa chitsulo kukhala yabwino kupanga nkhungu zomwe zimafuna kulimba kwambiri komanso kukana kuvala.

(4) Kudula kwabwino kwambiri: S136 chitsulo chofewa chimakhala ndi ntchito yabwino yodula, yosavuta kudula, mphero, kubowola ndi ntchito zina zopangira.Izi zimathandiza opanga kuti azitha kukonza mosavuta ndikuumba mafomu amitundu yovuta.

(5) Kukhazikika kwamafuta abwino: Chitsulo cha S136 chakufa chimakhala ndi kukhazikika kwamafuta ndipo chimatha kukhalabe olimba komanso mphamvu pansi pa malo otentha kwambiri.Izi zimapangitsa kukhala oyenera nkhungu ntchito kuti ayenera kupirira mkulu-kutentha mantha ndi kukakamizidwa.

(6) Kukana kwabwino kwa kuvala: S136 chitsulo chofa chimakhala ndi kukana kwabwino kwambiri ndipo chimatha kukana kukangana ndi kuvala.Izi zimapangitsa kuti zikhale zoyenera kupanga nkhungu zomwe ziyenera kugwiritsidwa ntchito kwa nthawi yayitali ndipo zimafuna kukana kwambiri kuvala.

(7) Pulasitiki ndi weldability: S136 kufa chitsulo ali plasticity wabwino ndi weldability, amene ndi yabwino kwa nkhungu kupanga ndi msonkhano.Panthawi imodzimodziyo, imatha kuwonjezera moyo wautumiki wa nkhungu pokonza zowotcherera.

Mwachidule, chitsulo cha S136 ndi chitsulo chofewa chomwe chimakhala ndi kukana kwa dzimbiri, kuuma kwakukulu, kuchita bwino kwa makina, kukhazikika kwamafuta komanso kukana kuvala.Amagwiritsidwa ntchito kwambiri popanga nkhungu, makamaka popanga nkhungu zomwe zimafuna kuuma kwakukulu, kukana kuvala komanso kukana dzimbiri.
