Ibha Yensimbi Engagqwali engu-440C
Incazelo emfushane:
Insimbi engagqwali engu-440C iyinsimbi engagqwali ye-martensitic enekhabhoni ephezulu eyaziwa ngokuqina kwayo okuhle kakhulu, ukumelana nokuguguleka, kanye nokumelana nokugqwala.
Amabha ensimbi engagqwali angu-440C:
Insimbi engagqwali engu-440C ingaqiniswa ukuze kufinyelelwe amazinga aphezulu obulukhuni, ngokuvamile cishe ku-58-60 HRC (isikali sobulukhuni beRockwell). Ingaphansi kochungechunge lwezinsimbi ezingagqwali ezingu-400, ezibonakala ngokuba nokuqukethwe okuphezulu kwekhabhoni, ngokuvamile cishe ku-0.60-1.20%, kanye nokumelana nokugqwala okumaphakathi. Inokumelana okuhle kokuguguleka, okwenza ifaneleke ukusetshenziswa njengezinsimbi zokusika, amathuluzi okusika, izinsimbi zokuhlinza, kanye nezingxenye zevalvu. Nakuba ingenakumelana nokugqwala njengezinsimbi ezingagqwali ze-austenitic (isb., 304, 316), i-440C inikeza ukumelana okuhle kokugqwala ezindaweni ezithambile. Imelana nokugqwala kakhulu kunezinye izinsimbi ezinekhabhoni ephezulu ngenxa yokuqukethwe kwayo kwe-chromium. Insimbi engagqwali engu-440C ingaphathwa ngokushisa ukuze kufinyelelwe izakhiwo zemishini ezifiselekayo.

Iyini i-440C Stainless Steel?
Insimbi engagqwali engu-440C inikeza ibhalansi yokumelana nokugqwala okuhle kanye nokumelana nokugqwala okulingene ezindaweni ezithambile, kanye nokuqina okuhle kakhulu. Ifana nebanga le-440B kodwa inokuqukethwe kwekhabhoni okuphezulu kancane, okuholela ebunzimeni obuphezulu kodwa ukumelana nokugqwala okuncishisiwe kancane uma kuqhathaniswa ne-440B. Ingafinyelela ubunzima obufika ku-60 Rockwell HRC futhi imelana nokugqwala ezindaweni ezivamile zasekhaya kanye nezimboni ezithambile, kanye nokumelana okuhle okufinyelelwa ngaphansi kwezinga lokushisa lokushisa elingu-400°C. Ukulungiswa kwendawo kubalulekile ekumelaneni nokugqwala okungcono kakhulu, okudinga ukususwa kwesikali, izinto zokugcoba, izinhlayiya zangaphandle, kanye nokugqoka. Okuqukethwe kwayo okuphezulu kwekhabhoni kuvumela ukushintshwa okufana namazinga ensimbi afakwe ngesivinini esiphezulu.
Ibha Engagqwali Eyindilinga engu-440C Isicelo:
Amabha ayindilinga ensimbi engagqwali angu-440C asetshenziswa kabanzi ekwenzeni imimese, amabheringi, amathuluzi okusika nokulungisa, amathuluzi ezokwelapha, izingxenye zamavalvu, kanye nemishini yezimboni, lapho ubulukhuni bawo obuphezulu, ukumelana nokuguguleka, kanye nokumelana nokugqwala okumaphakathi kwenza kube ukukhetha okuhle kwezingxenye ezibalulekile ezidinga ukusebenza okuhle kakhulu kanye nokuqina kwesikhathi eside.
Ukushisela kwensimbi engagqwali 440C:
Ngenxa yobunzima bayo obukhulu kanye nokulula kokuqinisa umoya, ukushisela insimbi engagqwali engu-440C akuvamile. Kodwa-ke, uma ukushisela kudingeka, kunconywa ukuthi kushiswe kusengaphambili izinto ku-260°C (500°F) bese kwenziwa ukwelashwa kokushisela ngemuva kokushisela ku-732-760°C (1350-1400°F) amahora ayi-6, kulandelwe ukupholisa kancane kwesithando somlilo ukuvimbela ukuqhekeka. Ukuqinisekisa izakhiwo ezifanayo zemishini kushisele njengasensimbini eyisisekelo, kufanele kusetshenziswe izinto ezisetshenziswayo zokushisela ezinokwakheka okufanayo. Ngaphandle kwalokho, i-AWS E/ER309 nayo ingabhekwa njengenketho efanelekile.
