Intsimbi yentsimbi eMild S20C S45C eHotyo iQhekelelwe ePhantsi yeKhabhoni eRound Bar eFakelweyo
  • Intsimbi yentsimbi eMild S20C S45C eHotyo eQhelekileyo yeKhabhoni eRound Bar

Inkcazelo emfutshane:

I-S20C yomelele kancinci kunentsimbi ye-15, ayifane icinywe, akukho brittleness enomsindo.Iplastiki ye-deformation ebanda kakhulu, esetyenziselwa ukugoba, i-calendering, ukugoba kunye ne-hammer arch processing, ukusebenza kakuhle kwe-arc welding kunye ne-welding yoqhagamshelwano, ubukhulu begesi ye-welding buncinci, iimfuno ezingqongqo zemilo okanye ubume obuntsokothileyo bomsebenzi kulula ukuqhekeka.I-machinability ye-cold-drawn or normalizing state iphezulu kune-annealed state.I-S20C isetyenziselwa ukwenza iindawo ezinoxinzelelo oluphantsi kunye neemfuno zokuqina okuphezulu.Ebandayo extruded, carburized lukhuni intsimbi.Intsimbi yeyentsimbi ethambileyo, intsimbi inamandla aphantsi, ukuqina, iplastiki kunye ne-weldability ilungile.Amandla esivuno ≥245MPa, amandla okuqina ≥402MPa, elongation ≥28%.I-normalizing inokukhuthaza i-spheroidization yezicubu, ukucokisa i-eutectoid ferrite eninzi kunye nokuphucula ukusebenza okungenanto ngaphantsi kwe-160HBS.

inzuzo

Intsimbi ye-S45C yenziwe ngentsimbi ecocekileyo ye-static ngesithando sombane, isithando somlilo esivulekileyo okanye inkqubo yokuguqula ioksijini ecocekileyo.Intsimbi ine-microstructure efanayo kwaye akukho ziphene ze-microstructure.Umxholo wekhabhoni wentsimbi ungaphezulu kwe-0.4%, ukuxhathisa okugqwesileyo kokunxiba, kodwa i-ductility iyancitshiswa, ukucima kulula ukuguqulwa kunye nokuqhekeka, ngoko ke unyango lobushushu lubaluleke kakhulu, kwaye kufuneka lucinywe emva kokuvutha, ukuphepha ukwenzeka ukucaphuka brittleness.Ukunyanzeliswa kolu hlobo lwentsimbi yekhabhoni kunokuphuculwa nge-spheroidizing intsimbi.I-S45C yintsimbi ekumgangatho ophezulu ophakathi kwekhabhoni.Ngokuqhelekileyo isetyenziswa phantsi komlilo oqhelekileyo.Xa iimpawu mechanical iimfuno eziphezulu, ukusetyenziswa unyango tempering.I-plastic deformation ebandayo ephakathi, i-annealing kunye ne-normalizing workability ingcono kunokufudumala.Isetyenziselwa ukwenza iinxalenye zokuvelisa ezifuna amandla aphezulu, njengegiya, i-shaft, i-piston pin, kunye ne-workpiece yomatshini, i-forging, i-stamping parts kunye ne-bolts, i-nuts, i-joint joints, njl. I-45C isetyenziswa ngokubanzi kwimveliso yoomatshini.Le ntsimbi ineempawu ezintle zoomatshini.
