Intsimbi engagqwaliyo yebanga lesi-3CR12 ludidi oluphantsi lwe-chromium equlethe intsimbi engagqwaliyo eyenziwe ngokutshintsha iipropati zentsimbi yebanga lesi-409. Iyamelana nokugqwala okuncinci kunye nokuguguleka okumanzi. Yaqalwa yaphuhliswa yiColumbus Stainless Company phantsi kophawu lwentengiso olubhalisiweyo "3CR12". Amanye amagama ale nqanaba aquka i-UNS S40977/S41003 kunye ne-1.4003.
Ezinye iindlela ezilingana neeklasi ze-3CR12 ziquka iiklasi ze-ASME SA240, iiklasi ze-ASTM A240/A240M, kunye ne-EN 10088.2. Nangona kunjalo, i-EN 10028.7 ikwagubungela iklasi ye-1.4003, eyila intsimbi engagqwaliyo ngeenjongo zoxinzelelo.
La macandelo alandelayo aza kubonelela ngeempawu eziphambili ze-coil yentsimbi engagqwaliyo ye-grade 3CR12, ishiti kunye nepleyiti ngokuhambelana ne-Euronorm S41003, S40977, ASTM A240/A240M kunye ne-EN 10088.2 1.4003.
Ezi zingentla zithelekiso nje ezingacwangciswanga. Le theyibhile yenzelwe ukubonelela ngothelekiso lwezinto ezifanayo ngokusebenza, kwaye iinkcukacha azikho mthethweni. Iinkcukacha zokuqala zingaqinisekiswa ukuba kufuneka izinto ezifanayo.
Intsimbi engagqwaliyo yeGrade 3CR12 ingasetyenziswa kwiindawo apho i-aluminium, i-galvanized okanye i-carbon steel inika iziphumo ezibi ngenxa yokuxhathisa kwayo kwi-asidi ezinamandla kunye neziseko, kunye nokuqhekeka okubangelwa kukubola koxinzelelo lwe-chloride. Nangona kunjalo, ngokungafaniyo neGrade 304, iGrade 3CR12 inokumelana okuphantsi kakhulu nokuqhekeka kwemingxuma kunye nokubola kwemingxuma xa kukho ii-chloride.
Phantsi kweemeko ezingqongileyo, i-3CR12 grade iphucule ukunyamezelana namanzi kunye nee-chloride, njengoko ukubola komxholo we-chloride kuncitshiswa yi-nitrate kunye nee-sulfate ions. Enye yezinto ezingalunganga ze-3CR12 grade kukuba umphezulu wezinto ubola kancinci xa ubekwe kuyo nayiphi na indawo. Kungenxa yesi sizathu le nto izinto zinqunyelwe kwizicelo zokuhombisa.
Intsimbi engagqwaliyo yodidi lwe-3CR12 ibonakalisa ukumelana nokungcoliswa phakathi kwama-600 kunye nama-750°C xa kukho umoya naphakathi kwama-450 kunye nama-600°C kwindawo exinezelekileyo. Le nto iba buthathaka xa ichaphazeleka ixesha elide kumaqondo obushushu aphakathi kwama-450 kunye nama-550°C. Nangona kunjalo, le nto ayilahlekelwa kukumelana kwayo nempembelelo kolu luhlu lwamaqondo obushushu.
Intsimbi engagqwaliyo yeGrade 3CR12 ifakwa kwi-700 ukuya kwi-750°C, yahlulwe yangamacandelo angama-25mm, icandelo ngalinye lifakwe emanzini kangangeyure ezili-1.5. Emva koko yivumele into iphole. Kufuneka kuqatshelwe ukuthintela ukuqina ngexesha lonyango lobushushu. Iimpawu zoomatshini kunye nokumelana nokugqwala kwale grade zichaphazeleka lunyango lokucima.
Iindlela zokuwelda ezisetyenziswa kwiintsimbi ezingenasici ze-austenitic zingasetyenziswa kwiintsimbi ezingenasici ze-grade 3CR12. Cinga ngeteknoloji yokufaka ubushushu obuphantsi ezifana ne-GMAW (MIG) kunye ne-GTAW (TIG). Kwi-welding, i-grade 309 filler wire eqinisekiswe kwangaphambili kwi-AS 1554.6 iyathandwa. Nangona kunjalo, ii-grades ze-308L, 316L, 309Mo kunye ne-309L zentambo nazo ziyasetyenziswa kwiimeko ezininzi. Nakuphi na ukutshintsha kombala kwimveliso ethengiswayo kunokususwa kusetyenziswa igesi yokuxhasa okanye iindlela ezifana nokucoca kunye nokuqhola.
Ubuchule bokusebenza kwentsimbi engatyiwayo ye-3CR12 bumalunga ne-60% yentsimbi ethambileyo. Izinga labo lokuqina liphantsi kunelentsimbi ye-austenitic, ngoko ke akukho ndlela ikhethekileyo yokulungisa inkunkuma efunekayo.
Iishethi zentsimbi engagqwaliyo zebanga le-3CR12 ziyafumaneka kwi-Hot Rolled Annealed and Pickled (HRAP) eqhelekileyo, kwaye ii-coil ziyafumaneka kwi-2B okanye i-2D finish. Iifinishi ezimnyama nazo zinokwenziwa ngezinto ezigoqiweyo ezishushu, zishiya umphezulu omnyama oxidiziweyo kwintsimbi. Iifinishi ezimnyama zebanga le-3CR12 zinokuxhathisa kakuhle ukugqwala kwaye zinoburhabaxa obuphantsi, ngoko ke zifanelekile kwiindlela ezahlukeneyo zokuguguleka.
Molo Richard, ndiyavuya ukukunika nayiphi na i-3Cr12. Sibonelela ngezinto eziphantsi kophawu lweCromgard C12. Nceda unditsalele umnxeba ku-719-597-2423. Jane Robinson.
