Umndeni wezinsimbi ezingagqwali uhlukaniswa ngokuyinhloko ngezigaba ezine eziyinhloko ngokusekelwe ku-crystal micro-structure.
I-Jindalai Steel Group ingumkhiqizi ohamba phambili kanye Nomthengisi wensimbi engagqwali ikhoyili/ishidi/ipuleti/i-strip/pipe. Sinekhasimende elivela ePhilippines, Thane, Mexico, Turkey, Pakistan, Oman, Israel, Egypt, Arab,Vietnam, Myanmar, India njll. Thumela uphenyo lwakho futhi sizokujabulela ukubonisana nawe ngokomsebenzi.
1. I-Ferritic
Izinsimbi ze-Ferritic ziyizinsimbi ezingenasici zeBanga lama-400 eziphawulwe ngokuqukethwe kwazo okuphezulu kwe-chromium, okungasukela ku-10.5% kuye ku-27%. Zinezakhiwo kazibuthe, futhi, zinikeza i-ductility enhle, ukuzinza kwe-tensile-property, nokumelana nokugqwala, ukukhathala okushisayo, nokuqhekeka kwe-stress-corrosion.
● I-Ferritic Stainless Steel Applications
Izicelo ezijwayelekile zezinsimbi ezingenasici ze-ferritic zifaka izingxenye zezimoto nezingxenye, imboni ye-petrochemical, izishintshi zokushisa, iziko, nasezimpahleni ezihlala isikhathi eside njengezinto zikagesi nempahla yokudla.
2. I-Austenitic
Mhlawumbe isigaba esivame kakhulu sensimbi engagqwali, izinsimbi ze-austenitic grade ziphezulu nge-chromium, enamanani ahlukahlukene enickel, manganese, nitrogen, kanye nekhabhoni ethile. Izinsimbi ze-Austenitic zihlukaniswe ngochungechunge lwe-300 kanye nezigatshana ezingu-200 zochungechunge, ezinqunywa ukuthi yiziphi ama-alloys asetshenziswayo. Isakhiwo se-austenitic sochungechunge lwe-300 sihlukaniswa ngokungezwa kwe-nickel. Uchungechunge lwama-200 lusebenzisa ngokuyinhloko ukungezwa kwe-manganese ne-nitrogen. Ibanga lama-304 yinsimbi engagqwali ejwayeleke kakhulu.
● Izicelo ze-Austenitic Stainless Steel
Kwesinye isikhathi ibizwa ngokuthi i-18/8 ngenxa ye-chromium engu-18% kanye ne-nickel engu-8%, isetshenziswa emishinini yasekhishini, izinto zokusika, izinto zokucubungula ukudla, kanye nezingxenye zesakhiwo embonini yezimoto ne-aerospace. IBanga 201, 304, 316 yinsimbi evamile engagqwali. Isetshenziswa ekwenzeni imikhiqizo enhlobonhlobo efana nemishini yokulungisa ukudla, amabhentshi aselabhorethri, okokwelashwa kanye nemishini yokuhlinza, okokufakwa ezikebheni, imithi, izindwangu kanye nemishini yokucubungula amakhemikhali.
3. I-Martensitic
Izinsimbi ezingenasici ze-Martensitic zikuchungechunge lweBanga lama-400 lezinsimbi ezingenasici. Zinokuqukethwe kwekhabhoni ephansi kuya kwephezulu futhi ziqukethe i-chromium engu-12% ukuya ku-15% kanye ne-molybdenum efika ku-1%. Isetshenziswa noma nini lapho ukumelana nokugqwala kanye-noma ukumelana ne-oxidation kuyadingeka kanye namandla aphezulu emazingeni okushisa aphansi noma ukumelana nokukhuphuka emazingeni okushisa aphakeme. Izinsimbi ze-Martensitic nazo zinguzibuthe futhi zine-ductility ephezulu kanye nokuqina, okwenza kube lula ukuwenza.
● I-Martensitic Stainless Steel Applications
Izicelo zezinsimbi ezingenasici ze-martensitic zifaka izinhlobonhlobo zezingxenye nezingxenye, kusukela kuma-compressor blades nezingxenye ze-turbine, izitsha zasekhishini, amabhawudo, amantongomane nezikulufu, izingxenye zephampu namavalvu, izinsimbi zamazinyo nezokuhlinza, kuya kumamotho kagesi, amaphampu, amavalvu, izingxenye zomshini. amathuluzi okuhlinza abukhali, izinto zokusika, izindwani zommese, namanye amathuluzi okusika isandla.
4. I-Duplex
Njengoba igama lisho, izinsimbi ezingenasici eziyi-duplex zine-microstructure exubile ye-ferrite ne-austenite. Okuqukethwe kwe-chromium ne-molybdenum kuphezulu, ngo-22% kuya ku-25%, futhi kufika ku-5%, ngokulandelana, nokuqukethwe kwe-nickel ephansi kakhulu. Isakhiwo esiyiduplex sinikeza insimbi engagqwali izinto eziningi ezifiselekayo. Okokuqala, inikeza amandla aphindwe kabili ezinsimbi ezivamile ze-austenitic noma ze-ferritic, ezinokumelana nokugqwala okuhle kakhulu kanye nokuqina.
● I-Duplex Stainless Steel Applications
Iqokwe ochungechungeni lweBanga lika-2000, insimbi engagqwali eyi-duplex ilungele ukusetshenziswa ezindaweni ezidinga kakhulu njengamakhemikhali, uwoyela, nokucubungula igesi kanye nemishini, olwandle, indawo ene-chloride ephezulu, imboni ye-pulp nephepha, amathangi emithwalo yemikhumbi namaloli, kanye ne-bio. -izitshalo ze-fuels, iziqukathi ze-chloride noma imikhumbi yokucindezela, ezokuthutha, amashubhu okushintshanisa ukushisa, ukwakhiwa, imboni yokudla, izitshalo zokukhipha usawoti emanzini, kanye nezingxenye zezinhlelo ze-FGD.
I-Jindalai Steel Group- umkhiqizi ohlonishwayo wensimbi engagqwali eChina. Ihlangabezana neminyaka engaphezu kwengu-20 yentuthuko ezimakethe zamazwe ngamazwe futhi njengamanje inamafekthri angu-2 anamandla okukhiqiza amathani angaphezu kuka-400,000 ngonyaka. Uma ufuna ukuthola ulwazi olwengeziwe mayelana nezinto zensimbi engagqwali, wamukelekile ukuthi usithinte namuhla noma ucele ikhotheshini.
