Ukwahlukanisa insimbi engagqwali:
Ukuzikisa ukuqina insimbi engagqwali
Ngokuqina okuhle nokuhleleka okuhle, kungasetshenziswa njengezinto ezinamandla amakhulu kakhulu embonini yenuzi, umkhakha wezindiza kanye nomkhakha we-aerospace.
Ingahlukaniswa ngohlelo lwe-CR (400 Series), uhlelo lwe-Cr Ni (300 Series), uhlelo lwe-Cr Mn Ni (200 Series), ukumelana nokushisa kwe-Cr alloy steel (500 Series) nohlelo lokuqinisa imvula (i-600 Series).
Uchungechunge lwama-200: Cr Mn Ni
Ngo-201202 njalonjalo: I-Manganese esikhundleni se-nickel inokumelana nokugqwala okungalungile futhi isetshenziswa kakhulu esikhundleni eshibhile se-300 Series e-China
Uchungechunge lwama-300: I-cr Ni insimbi engagqwali yensimbi
301: i-ductility enhle, esetshenziselwa imikhiqizo yokubumba. Kungabuye kwenziwe lukhuni ngokushesha ngomshini. I-weldability enhle. Amandla wokuqina kanye nokukhathala angcono kunensimbi engagqwali engu-304.
302: ukumelana nokugqwala kuyafana no-304, ngoba okuqukethwe kwekhabhoni kuphakeme kakhulu, amandla angcono.
303: ngokungeza inani elincane lesibabule ne-phosphorus, kulula ukusika kune-304.
304: imodeli yenhloso ejwayelekile; okungukuthi insimbi engagqwali engu-18/8. Imikhiqizo efana nale: iziqukathi ezingamelana nokugqwala, i-tableware, ifenisha, izinsimbi, imishini yezokwelapha. Ukwakheka okujwayelekile yi-18% ye-chromium ne-8% nickel. Kuyinsimbi engagqwali engeyona eyemagnetic isakhiwo sayo sensimbi esingeke siguqulwe ngokwelashwa kokushisa. Ibanga le-GB ngu-06cr19ni10.
304 L: izici ezifanayo ne-304, kepha i-carbon ephansi, ngakho-ke imelana nokugqwala, kulula ukushisa ukwelashwa, kepha izakhiwo zomshini ezingezinhle, ezifanele ukushisela futhi akulula ukushisa imikhiqizo yokwelashwa.
I-304 n: uhlobo oluthile lwensimbi engenasici equkethe i-nitrogen enezici ezifanayo nezingu-304. Inhloso yokwengeza i-nitrogen ukuthuthukisa amandla ensimbi.
309: inokumelana nokushisa okungcono kune-304, futhi ukumelana nokushisa kuphezulu njengo-980 ℃.
Ama-309 s: ngenani elikhulu le-chromium ne-nickel, inokumelana okuhle nokushisa nokumelana ne-oxidation, njengokushisa okushisa, izingxenye zebhayela kanye nenjini yomjovo.
310: ukumelana okuhle kakhulu kokushisa okuphezulu kokushisa, izinga lokushisa eliphakeme lokusebenzisa elingu-1200 ℃.
Ngo-316: ngemuva kuka-304, ibanga lensimbi elisetshenziswa kabanzi kunazo zonke lisetshenziswa kakhulu embonini yokudla, izesekeli zokubuka newashi, imboni yezemithi nemishini yokuhlinza. Ukungeza i-molybdenum element kuyenza ithole isakhiwo esikhethekile sokulwa nokugqwala. Ngenxa yokumelana kwayo kangcono ne-chloride corrosion kune-304, isetshenziswa futhi njenge "steel marine". I-SS316 ivame ukusetshenziselwa amadivayisi wokuvuselela uphethiloli wenuzi. Insimbi engagqwali yebanga le-18/10 ngokuvamile ihlangabezana naleli banga lokufaka isicelo.
I-316L: ikhabhoni ephansi, ngakho-ke imelana nokugqwala futhi kulula ukushisa ukwelashwa. Imikhiqizo efana nemishini yokucubungula amakhemikhali, i-generator yamandla enuzi, isitoreji sefriji.
321: ezinye izakhiwo zifana ne-304 ngaphandle kokuthi ubungozi be-weld corrosion buyancipha ngenxa yokwengezwa kwe-titanium.
I-347: engeza i-elementi yokuzinzisa i-niobium, elungele ukushisela izingxenye zensiza yezindiza nemishini yamakhemikhali.
Uchungechunge lwama-400: Insimbi engagqwali ye-Ferritic ne-martensitic, imanganese mahhala, ingathatha indawo yensimbi engenasici engama-304 ngezinga elithile
I-408: ukumelana nokushisa okuhle, ukumelana nokugqwala okubuthakathaka, 11% Cr, 8% Ni.
I-409: imodeli eshibhe kunayo yonke (yaseBrithani neyaseMelika), evame ukusetshenziswa njengepayipi lokukhipha imoto, ingeyensimbi engenasici i-ferritic (i-chromium steel).
410: i-martensite (amandla aphezulu e-chromium steel), ukumelana okuhle kokugqoka, ukumelana nokugqwala okungalungile.
416: ukwengezwa kwesibabule kuthuthukisa ukusebenza kwento leyo.
420: “grade cutting tool” i-martensitic steel, efana ne-Brinell high chromium steel, insimbi yokuqala engenasici. Ibuye isetshenziselwe imimese yokuhlinzwa. Kuyakhanya kakhulu.
430: insimbi engagqwali ye-ferritic, ukuhlobisa, isibonelo, izesekeli zezimoto. Ukuzinza okuhle, kepha ukumelana nokushisa okungekuhle nokumelana nokugqwala.
I-440: insimbi yensimbi yokusika amandla ephezulu, enokuqukethwe okungaphezulu kwekhabhoni, ingathola amandla aphezulu wesivuno ngemuva kokwelashwa okufanelekile kokushisa, futhi ubulukhuni bungafinyelela kuma-58hrc, ophakathi kwezinsimbi ezingenasici ezinzima kakhulu. Isibonelo esivame kakhulu sokufaka isicelo yi- “razor blade”. Kunamamodeli amathathu ajwayelekile: i-440A, i-440b, i-440C, ne-440f (kulula ukuyicubungula).
Uchungechunge lwe-500: i-chromium alloy steel engamelana nokushisa.
Uchungechunge lwama-600: IMartensite Precipitation Harding Insimbi engagqwali.
Insimbi engagqwali
Isikrini sensimbi engagqwali sibizwa nangokuthi insimbi yokuhlunga insimbi engagqwali ngoba isetshenziselwa ukuhlunga imikhiqizo.
Izinto: SUS201, 202, 302, 304, 316, 304L, 316L, 321 insimbi engagqwali ucingo, njll
