IBanga le-3CR12 insimbi engenasici lixabiso eliphantsi le-chromium equkethe insimbi engenasici eyenziwe ngokuguqula iimpawu ze-steel ye-409. Ichasa ukubola okuncinci kunye nokugqoka okumanzi.Yayiphuhliswe okokuqala yi-Columbus Stainless Company phantsi kophawu lwentengiso olubhalisiweyo "3CR12" .Amanye amagama ale bakala abandakanya i-UNS303 / S41907 kunye ne-S41907 kunye ne-S41907 kunye ne-S41907.
Ezinye izibizo ezilingana namabakala e-3CR12 ziquka amabakala e-ASME SA240, amabakala e-ASTM A240 / A240M, kunye ne-EN 10088.2.Nangona kunjalo, i-EN 10028.7 iphinda ihlanganise iklasi ye-1.4003, eyenza insimbi engenasici ngeenjongo zoxinzelelo.
Amacandelo alandelayo aya kubonelela ngeempawu eziphambili zebakala 3CR12 icoil yensimbi engenasici, ishidi kunye nepleyiti ngokuhambelana ne-Euronorm S41003, S40977, ASTM A240 / A240M kunye ne-EN 10088.2 1.4003.
Ezi zingentla ziluthelekiso nje olurhabaxa.Le theyibhile ijolise ekuboneleleni uthelekiso lwezixhobo zokusebenza ezifanayo, kwaye iinkcukacha azikho semthethweni.Iinkcukacha zantlandlolo zinokungqinwa ukuba ukulingana ngqo kuyafuneka.
I-Grade 3CR12 insimbi engenasici ingasetyenziselwa kwizicelo apho i-aluminium, i-galvanized okanye i-carbon steel inika iziphumo ezimbi ngenxa yokuchasana kwayo ne-acids eqinile kunye neziseko, kunye nokuqhekeka okubangelwa yi-chloride yoxinzelelo lwe-corrosion.Nangona kunjalo, ngokungafaniyo neBanga le-304, iBanga le-3CR12 linokumelana okuphantsi kakhulu kwi-crevice kunye ne-pitting corrosion phambi kobukho be-chlorides.
Ngaphantsi kweemeko ezingqongileyo, ibakala le-3CR12 liye laphucula ukunyamezela kwamanzi kunye nekloridi, njengoko ukubola komxholo we-chloride kuncitshiswe yi-nitrate kunye ne-sulfate ions.Enye yezinto ezingalunganga eziphambili zebakala 3CR12 kukuba umphezulu wezinto eziphathekayo unomhlwa xa ubonakaliswe kuyo nayiphi na into yokuhlobisa indalo.
I-3CR12 ye-stainless steel stainless grade ibonisa ukuchasana okungcolileyo phakathi kwe-600 kunye ne-750 ° C phambi komoya kunye naphakathi kwe-450 kunye ne-600 ° C kwindawo exinzelelekileyo.Izinto eziphathekayo ziba brittle kunye nokuvezwa kwexesha elide kumaqondo okushisa phakathi kwe-450 kunye ne-550 ° C. Nangona kunjalo, izinto eziphathekayo azilahleki ukuchasana kwempembelelo kule nqanaba lokushisa.
I-Grade 3CR12 insimbi engenasici ifakwe kwi-700 ukuya kwi-750 ° C, ihlulwe ibe ngamacandelo angama-25mm, icandelo ngalinye lifakwe kwiiyure ze-1.5. Emva koko vumela izinto ezipholileyo.Ukunyamekela kufuneka kuthathwe ukukhusela ukuqina ngexesha lonyango lobushushu.
Iindlela ze-welding ezisetyenziselwa i-austenitic stainless steels zingasetyenziselwa kwi-grade 3CR12 i-steels ezingenasici.Qwalasela iteknoloji yokufaka ukushisa okuphantsi njenge-GMAW (MIG) kunye ne-GTAW (TIG) . Kwi-welding, ibakala le-309 i-filler wire pre-certified to AS 1554.6 ikhethwayo.Nangona kunjalo, i-30L ye-308L, i-308L, i-308L, i-308L, i-308L imigangatho ye-308L. nazo zisetyenziswa kwiimeko ezininzi.Naluphi na ukuguqulwa kombala kwimveliso ethengiswayo kunokususwa kusetyenziswa igesi yenkxaso okanye ubuchule obunjengokucoca kunye nokukha.
I-machinability ye-3CR12 ye-stainless steel grade imalunga ne-60% yentsimbi epholileyo.Izinga lokuqina komsebenzi wabo liphantsi kuneentsimbi ze-austenitic, ngoko ke akukho ndlela zikhethekileyo zomatshini ezifunekayo.
Imigangatho ye-3CR12 ye-stainless steel sheets ifumaneka kwi-Hot Rolled Annealed kunye ne-Pickled (HRAP) esemgangathweni, kwaye iikhoyili zifumaneka kwi-2B okanye kwi-2D. Ukugqitywa kwe-Black kungaphinda kuveliswe kwizinto ezishushu ezishushu, zishiya indawo emnyama e-oxidized kwintsimbi. I-3CR12 ibakala elimnyama linokugqitywa kwe-corrosion ehlukeneyo kunye ne-friction ephantsi efanelekileyo, ukukhuhlana okuphantsi.
Molo Richard, ndiyavuya ukukubonelela ngayo nayiphi na ubungakanani be-3Cr12.Sibonelela ngezinto phantsi kwe-brand ye-Cromgard C12.Nceda unditsalele umnxeba ku-719-597-2423.Jane Robinson.
