Insimbi Engagqwali 304 1.4301

Insimbi engagqwali 304 kanye nensimbi engagqwali 304L yaziwa nangokuthi 1.4301 futhi 1.4307 ngokulandelana. Uhlobo 304 insimbi engagqwali enemisebenzi eminingi futhi esetshenziswa kabanzi. Ngezinye izikhathi kusabizwa ngegama layo elidala elithi 18/8 elisuselwe ekwakhiweni kwegama lohlobo 304 oluyi-18% chromium kanye ne-nickel engu-8%. Uhlobo 304 insimbi engagqwali iyizinga le-austenitic elingadonswa ngokujulile kakhulu. Lesi sakhiwo siholele ekutheni i-304 ibe yibanga eliphakeme elisetshenziswa ezinhlelweni ezinjengamasinki namapani. Uhlobo 304L inguqulo yekhabhoni ephansi engu-304. Isetshenziswa kuzingxenye zegeji esindayo ukuze kuthuthukiswe ukushisela. Eminye imikhiqizo efana namapuleti namapayipi ingase itholakale “njengezinto ezimbili eziqinisekisiwe” ezihlangabezana nemibandela yakho kokubili okungu-304 no-304L. 304H, okuhlukile kokuqukethwe kwekhabhoni ephezulu, nakho kuyatholakala ukuze kusetshenziswe emazingeni okushisa aphezulu. Izakhiwo ezinikezwe kuleli shidi ledatha zijwayelekile emikhiqizweni egoqelwe phansi embozwe i-ASTM A240/A240M. Kunengqondo ukulindela ukucaciswa kulawa mazinga ukuthi kufane kodwa kungafani nalezi ezinikezwe kuleli shidi ledatha.

Izimpawu ze-alloy

I-Stainless steel grade 1.4301/304 iphinde ihambisane ne: S30400, 304S15, 304S16, 304S31 kanye ne-EN58E.

Ukumelana Nokugqwala

I-304 inokumelana nokugqwala okuhle kakhulu ezindaweni zikaMeyi nalapho ixhumene nemidiya ehlukahlukene egqwalayo. Ukugqwala kwemigodi nokuqhekeka kungenzeka ezindaweni eziqukethe ama-chloride. Ukuqhekeka kokugqwala kwengcindezi kungenzeka ngaphezu kuka-60°C.

Ukumelana Nokushisa

I-304 inokumelana okuhle ne-oxidation kusevisi yesikhashana efika ku-870°C futhi enkonzweni eqhubekayo ukuya ku-925°C. Nokho, ukusetshenziswa okuqhubekayo ku-425- 860 ° C akunconywa. Kulesi sibonelo i-304L iyanconywa ngenxa yokumelana kwayo nemvula ye-carbide. Lapho amandla aphezulu edingeka emazingeni okushisa angaphezu kuka-500°C futhi kufika ku-800°C ibanga elingu-304H kuyanconywa. Le nto izogcina ukumelana nokugqwala okune-aqueous.

Ukwenziwa

Ukwenziwa kwazo zonke izinsimbi ezingenasici kufanele kwenziwe kuphela ngamathuluzi anikezelwe ezintweni zensimbi engagqwali. Amathuluzi nezindawo zokusebenza kufanele zihlanzwe kahle ngaphambi kokusetshenziswa. Lezi zinyathelo zokuphepha ziyadingeka ukuze kugwenywe ukungcoliswa okuphambana kwensimbi engagqwali ngezinsimbi ezigqwalile ezingase zishintshe umbala womkhiqizo owenziwe.

Ukusebenza Okubandayo

Insimbi engagqwali engu-304 isebenza kalula iba lukhuni. Izindlela zokukhiqiza ezibandakanya ukusebenza okubandayo zingase zidinge isigaba esimaphakathi sokuvala ukuze kuncishiswe ukuqina komsebenzi futhi kugwenywe ukuklebhuka noma ukuqhekeka. Lapho kuqedwa ukwakhiwa kufanele kusetshenziswe ukuhlinzwa okuphelele ukuze kuncishiswe izingcindezi zangaphakathi nokwandisa ukumelana nokugqwala.

Kuyashisa Ukusebenza

Izindlela zokukhiqiza ezifana nokubumba, okubandakanya ukusebenza okushisayo kufanele kwenzeke ngemva kokushisisa okufanayo ku-1149-1260°C. Izingxenye ezakhiwe kufanele zipholiswe ngokushesha ukuze kuqinisekiswe ukumelana nokugqwala okukhulu.

Ukusebenziseka kalula

I-304 inamandla okwenza kahle. Umshini ungathuthukiswa ngokusebenzisa le mithetho elandelayo: Imiphetho yokusika kufanele igcinwe ibukhali. Imiphetho ebuthuntu yenza umsebenzi ube lukhuni ngokweqile. Ukusikwa kufanele kube lula kodwa kujule ngokwanele ukuvimbela ukuqina komsebenzi ngokugibela phezu kwempahla. Ama-chip breakers kufanele asetshenziswe ukusiza ekuqinisekiseni ukuthi i-swarf ihlala ingenamsebenzi. Ukushisa okuphansi kwe-thermal alloys ye-austenitic kubangela ukugxila kokushisa emaphethelweni okusika. Lokhu kusho ukuthi izinto zokupholisa kanye nezinto zokugcoba ziyadingeka futhi kufanele zisetshenziswe ngobuningi.

Ukwelashwa Kokushisa

304 insimbi engagqwali ayikwazi ukwenziwa lukhuni ngokwelashwa okushisa. Ukwelashwa kwesixazululo noma ukucwiliswa kwamanzi kungenziwa ngokupholisa ngokushesha ngemva kokushisisa ku-1010-1120°C.

Ukushisela

Ukusebenza kwe-Fusion welding yohlobo lwe-304 yensimbi engagqwali kuhle kakhulu kokubili nangaphandle kwama-filler. Izinduku zokugcwalisa ezinconyiwe nama-electrode ensimbi engagqwali 304 iyinsimbi engagqwali yebanga lama-308. Ku-304L isigcwalisi esinconyiwe singama-308L. Izingxenye ezishiselwe esindayo zingase zidinge ukuhushula ngemuva kokushiselwa. Lesi sinyathelo asidingeki ku-304L. IBanga lama-321 lingasetshenziswa uma ukwelashwa kokushisa kwangemuva kwe-weld kungenzeki.
