Amabanga ayisisekelo ensimbi engagqwali

Okuvamile insimbi engagqwaliamamodeli
Amamodeli ensimbi engagqwali asetshenziswa ngokuvamile asetshenziswa izimpawu zezinombolo, kukhona 200 uchungechunge, 300 uchungechunge, 400 uchungechunge, kukhona ukumelwa United States of America, ezifana 201, 202, 302, 303, 304, 316, 410, 420, 430, njll., amamodeli ensimbi engenasici aseShayina asetshenziswa kuzimpawu zesici kanye nezinombolo, ezinjalo njenge-1Cr18Ni9, 0Cr18Ni9, 0Cr17, 3Cr13, 1Cr17Mn6Ni5N, njll., futhi izinombolo zibonisa okuqukethwe kwe-elementi ehambisanayo. 00Cr18Ni9, 1Cr17, 3Cr13, 1Cr17Mn6Ni5N njalo njalo, inombolo ikhombisa okuqukethwe kwe-elementi ehambisanayo.

200 uchungechunge: chromium-nickel-manganese austenitic insimbi engagqwali
300 uchungechunge: chromium-nickel austenitic insimbi engagqwali
301: I-ductility enhle, esetshenziselwa imikhiqizo ebunjiwe. Kungenziwa lukhuni futhi ngesivinini somshini. Ukushisela okuhle. Ukumelana nokugqoka namandla okukhathala kungcono kunensimbi engagqwali engu-304.
302: ukumelana nokugqwala nge-304, ngenxa yokuqukethwe kwekhabhoni ephezulu kakhulu ngakho-ke amandla angcono.
I-302B: Iwuhlobo lwensimbi engagqwali enokuqukethwe kwe-silicon ephezulu, enokumelana okuphezulu ne-oxidation yezinga eliphezulu lokushisa.
303: Ngokungeza inani elincane lesulfure ne-phosphorus ukuze ikwazi ukusebenza kahle.
I-303Se: Iphinde isetshenziselwe ukwenza izingxenye zomshini ezidinga isihloko esishisayo, ngoba le nsimbi engagqwali inokusebenza okuhle okushisayo ngaphansi kwalezi zimo.
304: 18/8 insimbi engagqwali. Ibanga le-GB 0Cr18Ni9. 309: ukumelana nokushisa okungcono kuno-304.
304L: Okuhlukile kwensimbi engagqwali engu-304 enokuqukethwe kwekhabhoni ephansi, esetshenziswa lapho kudingeka khona ukushisela. Okuqukethwe kwekhabhoni ephansi kunciphisa imvula yama-carbides endaweni ethinteke ukushisa eduze nendawo yokushisela, okungaholela ekugqwaleni kwe-intergranular (ukuguguleka kwe-weld) yensimbi engagqwali kwezinye izindawo.
I-304N: Insimbi engagqwali equkethe i-nitrogen, eyengezwa ukukhulisa amandla ensimbi.
I-305 kanye ne-384: Aqukethe amazinga aphezulu e-nickel, anezinga eliphansi lokuqina komsebenzi futhi afanele uhla olubanzi lwezinhlelo zokusebenza ezidinga ukwakheka okubandayo okuphezulu.
308: Isetshenziselwa ukwenza izinti zokushisela.
309, 310, 314 kanye no-330: okuqukethwe kwe-nickel ne-chromium kuphakeme uma kuqhathaniswa, ukuze kuthuthukiswe ukumelana ne-oxidation yensimbi emazingeni okushisa aphezulu namandla okukhasa. Nakuba i-30S5 ne-310S kuyizinhlobonhlobo ze-309 kanye ne-310 yensimbi engagqwali, umehluko ukuthi okuqukethwe kwekhabhoni kuphansi, ukuze ama-carbides agibele eduze nendawo yokushisela ancishiswe. Insimbi engagqwali engu-330 inokumelana okuphezulu kakhulu ne-carburization kanye nokumelana nokushaqeka kokushisa.
I-316 kanye ne-317: iqukethe i-aluminium, futhi ngaleyo ndlela ibe nokumelana okungcono kakhulu nokugqwala kwemigodi ezindaweni zasolwandle namakhemikhali kunezinsimbi ezingama-304. Phakathi kwabo, thayipha 316 insimbi engagqwalingokwezinhlobonhlobo zihlanganisa insimbi engagqwali enekhabhoni ephansi engu-316L, insimbi engagqwali eqinile engu-nitrogen engu-316N, kanye nokuqukethwe okuphezulu kwesibabule kwensimbi engenasici engu-316F yamahhala.
I-321, 347 kanye ne-348: yi-titanium, i-niobium plus tantalum, i-niobium stabilized steel stabilized, ifanele ukusetshenziswa emazingeni okushisa aphezulu ezingxenyeni ezishiselwe. I-348 iwuhlobo lwensimbi engagqwali efanele imboni yamandla enuzi, i-tantalum kanye nenani lokumba kuhlanganiswe nezinga elithile lokuvinjelwa.
400 uchungechunge: insimbi engagqwali ye-ferritic ne-martensitic
408: Ukumelana nokushisa okuhle, ukumelana nokugqwala okubuthakathaka, 11% Cr, 8% Ni.
409: uhlobo olushibhile (lwaseBrithani naseMelika), oluvame ukusetshenziswa njengamapayipi okukhipha umoya wezimoto, insimbi engagqwali ye-ferritic (insimbi ye-chromium)
I-410: i-martensitic (insimbi ye-chromium ephezulu), ukumelana nokugqokwa okuhle, ukumelana nokugqwala okubi. I-416: isulfure eyengeziwe ithuthukisa ukusebenza kwempahla.
420: "Izinga lethuluzi lokusika" insimbi ye-martensitic, efana ne-Brinell high-chromium steel, insimbi engagqwali yakuqala. Futhi esetshenziselwa imimese yokuhlinza futhi ingenziwa ikhanye kakhulu.
430: Insimbi engagqwali yeFerritic, ukuhlobisa, isb ezesekeli zemoto. Ukwakheka okuhle, kodwa ukumelana nezinga lokushisa nokumelana nokugqwala kuphansi.
I-440: insimbi enamandla amakhulu okusika, okuqukethwe kwekhabhoni ephakeme kancane, ngemuva kokwelashwa okushisa okufanele kungathola amandla aphezulu okukhiqiza, ubulukhuni bungafinyelela ku-58HRC, bube bensimbi engenasici enzima kakhulu. Isibonelo esisetshenziswa kakhulu "i-razor blades". Kunezinhlobo ezintathu ezivame ukusetshenziswa: 440A, 440B, 440C, kanye ne-440F (uhlobo olulula ukuya emshinini).
500 Series: Insimbi ye-chromium alloy engashi
600 Series: Martensitic precipitation-iqinisa insimbi engagqwali
630: Uhlobo lwensimbi engagqwali oluvame ukusetshenziswa kakhulu, oluvame ukubizwa ngokuthi i-17-4; 17% Cr, 4% Ni.
