20Cr ingxubevange ipayipi Seamless steelingelinye lamapayipi ensimbi enziwe nge-alloy anomkhiqizo omkhulu kunawo wonke ezweni lami futhi linokusetshenziswa okubanzi.Inombolo yensimbi ejwayelekile yaseShayina engu-20Cr;Inombolo yensimbi ejwayelekile ye-JIS yaseJapan SCr22;Inombolo yensimbi ejwayelekile ye-DIN engu-20Cr4;Inombolo yensimbi ejwayelekile yaseBrithani BS 590M17;Inombolo yensimbi ye-French NF ejwayelekile 18C3;Inombolo yensimbi ejwayelekile ye-AISI/SASTM 5120;I-International Standards Organisation ISO steel standard No. 20Cr4.
Izici
20Cr ingxubevange steel pipeinokuqina okuhle, amandla aphakathi nendawo kanye nokuqina.Ukuqina kokucisha uwoyela kuhhafu wokuqina kwe-martensitic kungu-Φ20-Φ23mm.Ngemuva kwe-carburizing kanye nokucisha ukwelashwa kokuqinisa ubuso, i-martensite enhle efana nenaliti izotholakala ebusweni besikhunta ngobulukhuni be-58-62HRC;isakhiwo se-martensite esinekhabhoni ephansi sizotholakala phakathi nendawo ngobulukhuni be-35-40HRC.I-matrix inamandla aphezulu kanye nokuqina, futhi ingahlangabezana nezidingo zokusebenza zokuqina okuphezulu, amandla aphezulu, ukuqina okuphezulu nokumelana nokugqwala okufanele kwezibungu zomsebenzi obandayo.Ukwenza ngokwejwayelekile kungathuthukisa i-spheroidization yesakhiwo, kucwengisise i-proeutectoid ferrite enkulu, futhi kuthuthukise ukusebenza kokusika kokungenalutho.
Ukusetshenziswa
20Cr amapayipi ensimbi angenamthungoasetshenziswa kakhulu ukwenza izingxenye ezishisiwe (ukucisha uwoyela) ezinezidingo zamandla aphezulu, ukugqokwa kwendawo, izingxenye eziwela ngaphansi kuka-30mm, noma ukwakheka okuyinkimbinkimbi nemithwalo ephansi, njengalezi: amagiya ebhokisi lamagiya ethuluzi lomshini, imiphini yegiya, Amakhamera, izikelemu, izikhonkwane zepiston. , izintambo zozipho, njll.;ezingxenyeni ezine-deformation encane yokwelashwa kokushisa nokumelana nokugqoka okuphezulu, ukucinywa kwe-high-frequency surface kufanele kwenziwe ngemva kwe-carburization, njengamagiya, ama-shafts.20Cr amapayipi angenamthungoingasetshenziswa futhi esimweni sokucisha nesithambile ukuze kukhiqizwe izingxenye ezisebenza ngesivinini esiphezulu futhi zimelane nemithwalo enomthelela omaphakathi.Ingasetshenziswa futhi njengensimbi yokucisha i-carbon martensitic ephansi ukuze kuqhutshekwe nokwandisa amandla okukhiqiza kanye namandla aqinile ensimbi.
