chitsulo chosapanga dzimbiri 316L chopiringidwa chubu chosinthira kutentha

316 zitsulo zosapanga dzimbiri zophimbidwa mapaipi ofotokozera muyezo:

Mipope yachitsulo chosapanga dzimbiri: ASTM A312 TP316/TP316L/TP316H, ASTM A269, ASTM A270

316/316L vs 304/304L

Mtundu wa 316/316L/316H ndi chitsulo chosapanga dzimbiri cha austenitic chomwe chimafuna kuti chizigwiritsidwa ntchito pamapulogalamu omwe amafunikira mphamvu zambiri, kulimba komanso kugwirira ntchito, komanso kukulitsa kukana dzimbiri.Poyerekeza ndi 304 zitsulo zosapanga dzimbiri, 316 ili ndi kuchuluka kwakukulu kwa molybdenum (Mo 2% -3%) ndi faifi (Ni 10% mpaka 14%), Molybdenum ili ndi kukana kwa dzimbiri kwabwinoko, makamaka popanga dzimbiri ndi kung'ambika m'malo a chloride.316 ili ndi mphamvu zolimba komanso zamakina pamatenthedwe apansi pa zero, oyenera kugudubuza kozizira, mbale yamphero yosalekeza ndi mawonekedwe amillplate, makulidwe ake mpaka mainchesi 60.

316L/TP316L Chitoliro Chachitsulo chosapanga dzimbiri

Gulu la 316L limatanthawuza S31603 UNS desination 1.4404, ili ndi kukana kwa dzimbiri bwino kuposa TP316 chifukwa cha Carbon yotsika.316L pazipita carbon zili 0.03% amene 316 pazipita 0.08%, carbon apamwamba adzawonjezera intergranular dzimbiri.Chifukwa chake, 316L ndiyoyenera kugwiritsa ntchito pomwe mpweya wa kaboni uyenera kupewedwa.Chitsulo chosapanga dzimbirichi chimagwiritsidwa ntchito kwambiri pakuwotcherera zigawo, zomwe zili ndi mpweya wapadera wophatikizidwa ndi kuwotcherera zimatsimikizira kukana kwakukulu kwa dzimbiri, makamaka zomwe zimagwiritsidwa ntchito pazinthu zolemetsa.

316L imatengedwa kuti ndi yosagwirizana kwambiri ndi okosijeni kuposa mtundu wa 316, makamaka m'madera otentha apanyanja.Apanso, kuchepa kwake kwa carbon kumateteza ku mpweya wa carbon.Chitsulocho chimasonyezanso kukana kutentha kwambiri, ngakhale mpaka kumagulu a cryogenic.Pankhani ya kukana kutentha, 316L imawonetsa kukana kwabwinoko, kukana kupsinjika kwa fracture ndi mphamvu zonse kuposa magiredi ena osapanga dzimbiri.

Njira zambiri zogwirira ntchito zomwe zili zovomerezeka za Type 316 zitha kugwiritsidwanso ntchito pa 316L, kuphatikiza kuwotcherera komanso kuuma kwa ntchito yozizira.Kuonjezera apo, 316 sichifuna kuti annealing pambuyo pa ntchito kuti apititse patsogolo kukana kwa dzimbiri, koma annealing angagwiritsidwe ntchito nthawi zina.

316H/TP316H Chitsulo chosapanga dzimbiri

Gulu la 316H limatanthawuza S31609, carbon content 0.04% mpaka 0.10%, imapereka kutentha kwakukulu kuposa 316L.

Chithunzi cha 316Ti/TP316Ti

Chitsulo chosapanga dzimbiri 316Ti chimadziwika ngati kalasi yokhazikika yamtundu wa 316 komanso ndi imodzi mwazitsulo zosapanga dzimbiri 316 zomwe zimalimbikitsidwa kuti zigwiritse ntchito kutentha kwambiri.Kalasi iyi imakhala ndi titaniyamu pang'ono (nthawi zambiri 0.5%).Ngakhale imagawana zambiri zamagulu ena a 316, kuwonjezera kwa titaniyamu kumateteza 316Ti ku mvula pa kutentha kwakukulu, ngakhale kuwonekera kwa nthawi yayitali.

Molybdenum imawonjezedwanso ku 316Ti.Monga magiredi ena a 316, molybdenum imapereka chitetezo chowonjezereka ku dzimbiri, kuyika kwa chloride solution ndi mphamvu ikayikidwa pamalo otentha kwambiri.Komabe, kukana kwake kutentha kwakukulu kumaphatikizidwanso ndi titaniyamu, zomwe zimapangitsa 316Ti kuti isamakhale ndi mvula pamatenthedwe awa.Kuphatikiza apo, chitsulocho chimagonjetsedwa ndi zidulo monga sulfuric acid, hydrochloric acid, ndi acid sulfates.
316Ti imagwiritsidwa ntchito kwambiri posinthanitsa kutentha, zida zamapepala ndi zida zomangira m'malo am'madzi.

Mtengo wa TP316LN/316N

316N: Nayitrogeni (N) amawonjezeredwa ku zitsulo zosapanga dzimbiri 316 kuti awonjezere mphamvu popanda kuchepetsa pulasitiki, kuti makulidwe a zinthuzo achepetse.Kwa magawo amphamvu kwambiri okhala ndi kukana kwa dzimbiri bwino.

316LN nayonso ndi 316L yokhala ndi N yowonjezeredwa, ili ndi kukana kwa dzimbiri kuposa 316N.

TP316/316L/316H/316Ti Mapaipi Osapanga zitsulo

TP316 / 316L chitoliro chosasunthika chimagwiritsidwa ntchito potengera madzi kapena mpweya kutengerapo madzi, kuthira madzi oyipa, petrochemical, mankhwala, mankhwala ndi mafakitale ena.Ndipo ntchito zomangika zimaphatikizirapo ma handrail, mitengo ndi mapaipi othandizira madzi amchere ndi malo owononga.Poyerekeza ndi TP304 chitsulo chosapanga dzimbiri, chitoliro cha TP316 chosapanga dzimbiri chimakhala ndi weldability wocheperako, chifukwa chake sichimagwiritsidwa ntchito nthawi zambiri ngati chitoliro chowotcherera pokhapokha ngati kukana kwake kwa dzimbiri kukuposa kuwotcherera.
