Iishiti zentsimbi engagqwaliyo zinomphezulu ogudileyo, ziqinile kakhulu, ziqinile, kwaye zinamandla oomatshini, kwaye ziyamelana nokugqwala okuvela kwiigesi ze-asidi kunye ne-alkaline, izisombululo, kunye nezinye izinto ezisetyenziswayo. Yintsimbi ye-alloy engagqwali lula, kodwa ayimelani nokugqwala ngokupheleleyo. Iishiti zentsimbi engagqwaliyo zibhekisa kwiishiti zentsimbi ezingamelani nokugqwala ezivela kwizinto ezibuthathaka ezifana nomoya, umphunga, namanzi, ngelixa iishiti zentsimbi ezingamelani ne-asidi zibhekisa kwiishiti zentsimbi ezingamelani nokugqwala ezivela kwizinto ezisetyenziswayo ezisebenzisa iikhemikhali ezisebenzisa iikhemikhali ezisebenzisa ii-asidi, ii-alkali, kunye neetyuwa.
Amashiti entsimbi engagqwaliyo afumaneka kwiindidi ezahlukeneyo, kunye nothotho olubaluleke kakhulu kwezorhwebo oluquka i-austenitic, i-ferritic, i-duplex, kunye ne-martensitic. Uhlobo ngalunye luneempawu ezizodwa zoomatshini kunye nokumelana nokugqwala, okwenza ukuba lufaneleke kwizicelo ezithile.
Intsimbi Engagqwaliyo yaseAustenitic (Uthotho lwama-300)
304/304L: Intsimbi engagqwaliyo esetyenziswa ngokubanzi. Inokumelana nokugqwala okuhle, ukwakheka kakuhle, kunye nokudityaniswa kakuhle.
316/316L: Xa kongezwe i-2-3% ye-molybdenum, inokumelana okuhle kakhulu ne-chloride (amanzi olwandle, ityuwa yokususa i-icing).
321: Ngokongeza iziqinisi zetitanium, ithintela uvakalelo ngexesha lokuwelda.
310S: Umgangatho wobushushu obuphezulu (ukuya kuthi ga kwi-1100°C), ifanelekile kwiindawo zesithando somlilo.
Intsimbi Engagqwaliyo yeFerritic (uthotho lwama-400, umz., 430, 409, 439) Amaphepha entsimbi engagqwaliyo yeFerritic aqulathe i-10.5%–27% yechromium, umxholo wekhabhoni ophantsi kakhulu (<0.1%), kwaye i-nickel incinci kakhulu okanye ayinayo kwaphela. Anemagnethi kwaye anokumelana kakuhle nokuqhekeka koxinzelelo, kodwa ukwakheka kwawo kunye nokuqina kwawo kungaphantsi kwentsimbi engagqwaliyo ye-austenitic. Azinakuqiniswa ngonyango lobushushu. Izicelo eziqhelekileyo: iinkqubo zokukhupha umoya kwiimoto, iiphaneli zokwakha, kunye nezixhobo zombane zangaphakathi. Kwiindawo ezithambileyo, i-grade 430 yindlela eqhelekileyo engabizi kakhulu kune-grade 304.
Intsimbi Engagqwaliyo Ephindwe Kabini (umz., 2205, 2507) Intsimbi engagqwaliyo Ephindwe Kabini inesakhiwo esincinci esiqulathe umxube wezinto ze-austenitic kunye ne-ferritic (malunga ne-50/50). Ngenxa yomxholo wayo ophezulu we-chromium (21-26%), umxholo ophakathi we-nickel (4-7%), kunye nomxholo we-molybdenum (0-4%), intsimbi engagqwaliyo ye-2205 inamandla okuvelisa aphindwe kabini kunentsimbi engagqwaliyo ye-austenitic, ngelixa igcina ukumelana okuhle kakhulu nokuqhekeka kwe-chloride stress corrosion. Intsimbi engagqwali ye-2205 isetyenziswa kakhulu kwiinqanawa zamakhemikhali, ukususwa kwetyuwa emanzini olwandle, kunye nee-pulp digesters. Amandla ayo aphezulu avumela ukusetyenziswa kwamaphepha amancinci, ngaloo ndlela kunciphisa ubunzima kunye neendleko.
Intsimbi engagqwaliyo yeMartensitic (umz., 410, 420) iqulethe i-11-17% ye-chromium kunye nomxholo ophezulu wekhabhoni (0.1-1.2%), nto leyo evumela ukuqina ngonyango lobushushu. Zinamandla, zinamandla, kwaye azigugi, kodwa ukumelana kwazo nokugqwala kuphantsi kunokwentsimbi engagqwaliyo ye-austenitic okanye ye-duplex.
Umahluko ophambili phakathi kweepleyiti zentsimbi engagqwali ezingama-304 kunye nama-316: intsimbi engagqwali engama-304, esidibana nayo imihla ngemihla, yindlela efanelekileyo yokusebenzisa intsimbi engagqwali ekumgangatho wokutya kunye nokumkani wokusebenza kakuhle kweendleko kwiindlela zasekhaya. Iqhayisa ngokuxhathisa ukugqwala okugqwesileyo, ukuthintela ukugqwala, kunye nokumelana nobushushu obuphezulu. Kwiikomityi ezigqunyiweyo, izitya zetafile, izinki zasekhitshini, izixhobo zokulungisa ukutya, kunye nezixhobo zegumbi lokuhlambela, i-304 lukhetho olufanelekileyo. Ikhuselekile, ayinatyhefu, kwaye ayigqwali ukusetyenziswa imihla ngemihla, ifanelekile kwiimeko ezininzi zasekhaya, kwaye inika ukuqina okugqwesileyo.
Kwelinye icala, i-316 stainless steel sisixhobo esikumgangatho ophezulu kwezonyango/esikumgangatho ophezulu kwimizi-mveliso. Yongeza i-molybdenum kwi-304, iphucula kakhulu ukumelana kwayo nokugqwala, ukumelana ne-asidi kunye ne-alkali, kwaye iyenza imelane ngakumbi namaqondo obushushu aphezulu kunye nokugqwala kwamanzi olwandle. Isetyenziswa kakhulu kwizixhobo zasekhitshini ezikumgangatho ophezulu, izixhobo zonyango, imibhobho yamakhemikhali, kunye nezibonelelo zangaphandle zonxweme. Nangona ingafuneki ekusetyenzisweni kwemihla ngemihla ekhaya, i-316 sisisombululo esifanelekileyo kwizicelo ezifuna ukumelana nokugqwala okuphezulu.
Omnye umahluko obalulekileyo ukwixabiso; ngenxa yomxholo wayo ophezulu we-nickel kunye ne-molybdenum, intsimbi engagqwaliyo engama-316 idla ngokubiza kakhulu kunentsimbi engagqwali engama-304. Ke ngoko, ukhetho phakathi kwezi ntsimbi zimbini ludla ngokuxhomekeka kwiimfuno ezithile zokusetyenziswa, kubandakanya imida yohlahlo-lwabiwo mali kunye neemeko zokusingqongileyo.
Intsimbi engagqwaliyo yinto yobunjineli eguquguqukayo kakhulu, ingakumbi iiklasi ezingama-304 kunye nama-316, ezidlala indima ebalulekileyo kumashishini ahlukeneyo ngenxa yeempawu zazo ezizodwa kunye nokusetyenziswa kwazo. Nokuba kumashishini okulungisa ukutya, ukwakha, iimoto, ezonyango, amachiza, okanye amandla, amaphepha entsimbi engagqwaliyo ebesoloko eyindlela ethembekileyo yokukhetha iinjineli kunye nabavelisi. Njengoko amashishini eqhubeka nokutshintsha kwaye imfuno yezinto ezihlala ixesha elide, ezingamelani nokugqwala iqhubeka ikhula, ukubaluleka kwamaphepha entsimbi engagqwaliyo kuya kwanda kuphela.
Ukuba ufuna ukuthenga iimveliso zeshiti yentsimbi engagqwaliyo, nceda ucofe ukuze unxibelelane nathi ukuze ufumane iingcebiso. IJindalai Steel Group Co., Ltd. iza kukunika iimpendulo zobungcali.
