20Cr ingxubevange intsimbi umbhobho ingenamthungongomnye wemibhobho yentsimbi yolwakhiwo enemveliso enkulu kwilizwe lam kwaye inoluhlu olubanzi losetyenziso.Inombolo yaseTshayina ye-GB yentsimbi ye-20Cr;Inombolo yentsimbi esemgangathweni yeJIS yaseJapan SCr22;I-DIN yesiJamani inombolo yentsimbi esemgangathweni 20Cr4;Inombolo yentsimbi yaseBritani yeBS 590M17;Inombolo yentsimbi yesiFrentshi yeNF 18C3;I-American AISI / SASTM inombolo yentsimbi esemgangathweni 5120;Umbutho weMigangatho yaMazwe ngaMazwe ISO yentsimbi esemgangathweni No. 20Cr4.
Iimpawu
20Cr ingxubevange yentsimbi umbhobhoinokuqina okufanelekileyo, ukomelela okuphakathi kunye nokuqina.Ukuqina kokucima ioli ukuya kwisiqingatha sobunzima be-martensitic yi-Φ20-Φ23mm.Emva kwe-carburizing kunye nokucima unyango lokuqiniswa kwendawo, i-martensite epholileyo efana nenaliti iya kufumaneka kumphezulu we-mold kunye nobunzima be-58-62HRC;isakhiwo se-martensite esisezantsi siya kufumaneka kwiziko kunye nobunzima be-35-40HRC.I-matrix inamandla aphezulu kunye nokuqina, kwaye inokuhlangabezana neemfuno zokusebenza zobunzima obuphezulu, ukomelela okuphezulu, ukuqina okuphezulu kunye nokuchasana kokuhlwa okufanelekileyo kokungunda komsebenzi obandayo.I-normalizing inokukhuthaza i-spheroidization yesakhiwo, ukucokisa i-proeutectoid ferrite enkulu, kunye nokuphucula ukusebenza kokusika okungenanto.
Ukusetyenziswa
20Cr imibhobho yentsimbi engenamthungoubukhulu becala zisetyenziselwa ukwenza iinxalenye ze-carburized (ukucinywa kweoyile) ezineemfuno zamandla aphezulu, ukunxiba komphezulu, amacandelo anqamlezayo angaphantsi kwe-30mm, okanye iimilo ezintsonkothileyo kunye nemithwalo ephantsi, enje: iigiya zebhokisi yesixhobo somatshini, iishafu zegiya, iiCam, iintshulube, izikhonkwane zepiston. , ukubamba uzipho, njl. njl.;kumalungu ane-deformation encinci yonyango lobushushu kunye nokumelana nokunxiba okuphezulu, ukucinywa komphezulu okujikelezayo kufuneka kwenziwe emva kwe-carburization, enje ngegiya, i-shafts.20Cr imibhobho engenamthungoingasetyenziselwa kwimeko ecinyiweyo kunye nenomsindo ukwenza iindawo ezisebenza ngesantya esiphezulu kwaye zimelane nemithwalo yempembelelo ephakathi.Isenokusetyenziswa njengentsimbi ephantsi ye-carbon martensitic yokucima ukunyusa ngakumbi amandla esivuno kunye namandla okuqina entsimbi.
