I-Mild Steel S20C S45C Eshisayo Egingqiwe Ibha Ejikelezayo Yekhabhoni Ephansi Isithombe Esifakiwe
  • I-Mild Steel S20C S45C Ibha Eyindingilizi Eshisiwe Eshisiwe Yekhabhoni Ephansi

Incazelo emfushane:

I-S20C iqine kancane kunensimbi engu-15, ayivamisile ukucishwa, akukho brittleness eshisayo.I-plasticity ephezulu ye-deformation ebandayo, ngokuvamile esetshenziselwa ukugoba, i-calendering, ukugoba kanye nokucubungula i-arch yesando, ukusebenza kahle kwe-welding arc welding kanye ne-welding yokuxhumana, ukuqina kwegesi yokushisela kuncane, izidingo zomumo oqinile noma ukuma okuyinkimbinkimbi kwe-workpiece kulula ukuqhekeka.I-machinability yesimo esidonswa ukubanda noma esijwayelekile siphakeme kunesimo sokucwila.I-S20C isetshenziselwa ukwenza izingxenye ezinengcindezi ephansi kanye nezidingo zokuqina okuphezulu.Ebandayo extruded, carburized hardened steel.Insimbi ingeyensimbi emnene, insimbi inamandla aphansi, ukuqina, ipulasitiki kanye nokushisela kuhle.Amandla okukhiqiza ≥245MPa, amandla aqinile ≥402MPa, ubude ≥28%.Ukwenza okujwayelekile kungakhuthaza i-spheroidization yezicubu, kucolise inqwaba ye-eutectoid ferrite futhi kuthuthukise ukusebenza kokungenalutho ngaphansi kuka-160HBS.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

incazelo yemikhiqizo

I-cold deformation plasticity iphezulu, ngokuvamile yokugoba, i-calendering, ukugoba kanye nokucubungula i-arch yesando, ukusebenza kwe-welding ye-arc welding kanye ne-welding yokuxhumana kuhle, ukushuba kwe-gas welding kuncane, ukwakheka kwezidingo eziqinile noma ukuma okuyinkimbinkimbi kwe-workpiece kulula ukuqhekeka. .Ebandayo extruded, carburized hardened steel.Insimbi ingeyensimbi ye-carbon carbon ephansi, insimbi inamandla aphansi, ukuqina, ipulasitiki kanye nokushisela kuhle.≥245MPa, ≥402MPa, ≥28%.Isetshenziselwa ukukhiqiza izingxenye ezihlukahlukene zemishini ezingenaso ingcindezi enkulu kodwa ezidinga ukuqina okuphezulu.Emishinini ejwayelekile nasemotweni, imishini yezolimo yokwenza izidingo zokuqina kobuso obuphezulu kanye nezidingo zenhliziyo zezingxenye zokungcwaba kanye nezingxenye zokungcwaba.

Isebenzisa

I-cold deformation plasticity iphezulu, ngokuvamile yokugoba, i-calendering, ukugoba kanye nokucubungula i-arch yesando, ukusebenza kwe-welding ye-arc welding kanye ne-welding yokuxhumana kuhle, ukushuba kwe-gas welding kuncane, ukwakheka kwezidingo eziqinile noma ukuma okuyinkimbinkimbi kwe-workpiece kulula ukuqhekeka. .Ebandayo extruded, carburized hardened steel.Insimbi ingeyensimbi ye-carbon carbon ephansi, insimbi inamandla aphansi, ukuqina, ipulasitiki kanye nokushisela kuhle.≥245MPa, ≥402MPa, ≥28%.Isetshenziselwa ukukhiqiza izingxenye ezihlukahlukene zemishini ezingenaso ingcindezi enkulu kodwa ezidinga ukuqina okuphezulu.Emishinini ejwayelekile nasemotweni, imishini yezolimo yokwenza izidingo zokuqina kobuso obuphezulu kanye nezidingo zenhliziyo zezingxenye zokungcwaba kanye nezingxenye zokungcwaba.

inzuzo

Insimbi ye-S45C yenziwe ngensimbi ehlanzekile emile ngesithando somlilo sikagesi, isithando somlilo esivulekile noma inqubo yokuguqula umoya-mpilo omsulwa.Insimbi ine-microstructure efanayo futhi ayinazo iziphambeko ze-microstructure.Okuqukethwe kwekhabhoni yensimbi kungaphezu kuka-0.4%, ukumelana okuhle kakhulu kokugqoka, kepha i-ductility iyancipha, ukucisha kulula ukuguqulwa nokuqhekeka, ngakho-ke ukwelashwa kokushisa kubaluleke kakhulu, futhi kufanele kucinywe ngemuva kokushisa, ukugwema ukuvela ukuphefumula kwe-brittleness.I-machinability yalolu hlobo lwe-carbon steel ingathuthukiswa ngokufaka i-spheroidizing insimbi.I-S45C iyinsimbi enamandla kakhulu esezingeni eliphakathi nekhabhoni.Ngokuvamile isetshenziswa ngaphansi komlilo ojwayelekile.Lapho izakhiwo mechanical izidingo eziphakeme, ukusetshenziswa ukwelashwa tempering.Cold deformation plasticity medium, annealing and normalizing ukusebenza kahle kungcono kunokushisa.Isetshenziselwa ukukhiqiza izingxenye ezidinga amandla aphezulu, njengegiya, i-shaft, iphinikhodi ye-piston, kanye nomshini wokusebenza, ukubumba, izingxenye zokugxiviza namabhawudi, amantongomane, amalunga amapayipi, njll. I-45C isetshenziswa kabanzi ekukhiqizeni imishini.Le nsimbi inezimfanelo ezinhle zemishini.
