440C Ibha Yensimbi Engagqwali
Incazelo emfushane:
I-440C insimbi engagqwali iyinsimbi engagqwali enekhabhoni ephezulu enekhabhoni eyaziwa ngokuba lukhuni kwayo, ukumelana nokugqwala, nokumelana nokugqwala.
Amabha Ensimbi Engagqwali 440C:
Insimbi engagqwali engu-440C ingaqiniswa ukuze kufinyelelwe amazinga aphezulu okuqina, ngokuvamile azungeze u-58-60 HRC (isikalo sokuqina sokuqina kwe-Rockwell) .Ingochungechunge lwama-400 lwensimbi engagqwali, ebonakala ngokuba nekhabhoni ephezulu, ngokuvamile elinganiselwa ku-0.60-1.20% , kanye nokumelana nokugqwala okusesilinganisweni.Inokumelana nokugqokwa okuhle kakhulu, okuyenza ifaneleke ukusetshenziswa njengamabheringi, amathuluzi okusika, amathuluzi okuhlinza, nezingxenye zamavalvu.Yize ingenamandla okumelana nokugqwala njengezinsimbi ezingenasici ze-austenitic (isb, 304, 316), 440C. inikeza ukumelana nokugqwala okuhle ezindaweni ezithambile. Ikwazi ukumelana nokugqwala kunezinye izinsimbi ezinekhabhoni ephezulu ngenxa yokuqukethwe kwayo kwe-chromium.440C insimbi engagqwali ingaphathwa ngokushisa ukuze kuzuzwe izakhiwo ezifiselekayo zokulungisa.

Iyini i-440C Stainless Steel?
Insimbi engagqwali engu-440C inikeza ibhalansi yokumelana nokugqokwa okuhle nokumelana nokugqwala okusesilinganisweni ezindaweni ezithambile, ngokuqina okuhle kakhulu. Ihlanganyela ngokufana nebanga le-440B kodwa inokuqukethwe kwekhabhoni ephakeme kancane, okuholela ebukhuni obuphakeme kodwa ukunqanda ukugqwala okunciphile uma kuqhathaniswa no-440B. Ingafinyelela ubulukhuni obufika ku-60 Rockwell HRC futhi imelana nokugqwala endaweni evamile yasekhaya nezimboni ezithambile, ngokumelana okufanelekile okutholakala ngaphansi kwezinga lokushisa elicishe libe ngu-400°C. Ukulungiswa komphezulu kubalulekile ukuze kumelane nokugqwala okungcono kakhulu, kudinga ukususwa kwesikali, izinto zokugcoba, izinhlayiya zangaphandle, nama-coatings. Okuqukethwe kwayo kwekhabhoni ephezulu kuvumela ukwenziwa kwemishini efana ne-annealed high-speed steel grade.
Isicelo se-440C Stainless Steel Round Bar:
Imigoqo eyindilinga engu-440C yensimbi engenasici isetshenziswa kabanzi ekwenzeni ummese, ama-bearings, amathuluzi okuthululela nokusika, amathuluzi ezokwelapha, izingxenye zevalvu, kanye nemishini yezimboni, lapho ubulukhuni bayo obuphezulu, ukumelana nokugqoka, nokumelana nokugqwala okusesilinganisweni kubenza babe izinqumo ezifanele zezingxenye ezibalulekile ezidinga okuhle kakhulu. ukusebenza kanye nokuqina kwesikhathi eside.
Welding of Stainless Steel 440C:
Ngenxa yokuqina kwayo okuphezulu nokulula kokuqina komoya, ukushisela kwensimbi engagqwali engu-440C akuvamile. Kodwa-ke, uma ukushisela kuba kudingekile, kunconywa ukuthi ushise kuqala impahla ibe ngu-260 ° C (500 ° F) futhi wenze ukwelashwa kwe-post-weld annealing ku-732-760 ° C (1350-1400 ° F) amahora angu-6, kulandelwa ukupholisa kancane kwesithando somlilo ukuvimbela ukuqhekeka. Ukuqinisekisa izici ezifanayo zemishini ku-weld njengasensimbi eyisisekelo, izinto ezisetshenziswayo zokushisela ezinokwakheka okufanayo kufanele zisetshenziswe. Kungenjalo, i-AWS E/ER309 ingase futhi ibhekwe njengenketho efanelekile.
