316 pombi yesimbi isina tsvina
316 Stainless simbi ndiyo inonyanya kushandiswa simbi kunze kwe304 Stainless simbi, uye chigadzirwa chakakwidziridzwa che304 Stainless simbi.Nekuda kwekuwedzera kweMo, ine yakanaka corrosion resistance, marine uye mumhepo yekunze corrosion resistance, yakanakisa tembiricha yekudzivirira, uye kuita kwakanaka kwewelding.
316 simbi isina tsvina ine huwandu hwakawanda hwekushandisa, inonyanya kushandiswa mumakemikari, dhayi, bepa, oxalic acid, midziyo yemvura yegungwa, kugadzira chikafu, kurapwa, bhaudhi, nzungu maindasitiri.
Pamusoro pezvishandiso zvemaindasitiri, tinoonawo 316 simbi isina tsvina muhupenyu hwezuva nezuva, senge mbiya dzemupunga dzinowanzo shandiswa simbi, makapu emvura esimbi isina simbi, uye mbiru dzesimbi dzisina simbi.316 Stainless simbi ine zvirinani corrosion resistance uye acid resistance, saka inonyanya kushandiswa mumishonga neindasitiri.
Izvo zvinhu zve 316 simbi isina tsvina pombi
1. Corrosion resistance
Kupokana necorrosion kuri nani pane 304 simbi isina tsvina, uye ine yakanaka yekurasa kuramba mukugadzirwa kwe pulp nebepa.Uye 316 simbi isina tsvina zvakare inoshingirira kukukurwa nemakungwa uye ane hukasha maindasitiri mamiriro.
2. Kudzivisa kupisa
316 simbi isina tsvina (06Cr17Ni12Mo2) ine yakanaka oxidation kuramba mukushandiswa kwepakati pasi pe871 ° C (1600 ° F) uye kushandiswa kunoramba kuripo pamusoro pe927C ° (1700 ° F).Mukati me427 ° C-857 ° C (800 ° F-1575 ° F), zviri nani kuti usashandise 316 simbi isina tsvina nguva dzose, asi simbi isina tsvina ine yakanaka yekupisa kana ichishandiswa nguva dzose kunze kweiyi tembiricha.Iyo carbide precipitation resistance ye316L simbi isina tsvina iri nani pane iya ye316 Stainless simbi, uye tembiricha iri pamusoro inogona kushandiswa.
3. Kurapa kwekupisa
Yakanamirwa mumhando yekushisa ye850-1050 ° C, inoteverwa nekukurumidza kuvhara, inoteverwa nekukurumidza kutonhora.316 simbi isina tsvina haigoni kuomeswa nekurapa kwekupisa.
4. Welding
316 simbi isina tsvina ine yakanaka weldability.Yese yakajairwa welding nzira dzinogona kushandiswa kugadzira.Zvinoenderana nemashandisirwo, 316Cb, 316L kana 309Cb simbi isina simbi yekuzadza tsvimbo kana maelectrode anogona kushandiswa kugadzira.Kuti uwane iyo yakanakisa corrosion resistance, iyo welded chikamu che316 Stainless simbi inoda kuve post-weld annealed.Post weld annealing haidiwe kana 316L simbi isina tsvina ikashandiswa.
Kushandiswa kwepombi ye316 simbi isina tsvina
316 Stainless simbi pombi imhando yegomba yakareba yakatenderedza simbi pombi, iyo inonyanya kushandiswa mumaindasitiri ekufambisa mapaipi uye nemwaka maumbirwo ezvikamu zvakaita se petroleum, indasitiri yemakemikari, kurapwa, chikafu, indasitiri yemwenje, chiridzwa chemuchina uye zvichingodaro.316 Stainless simbi pombi ine yakanyanya kabhoni yemukati ye0.03 uye inogona kushandiswa mumashandisirwo apo annealing mushure mewelding haigone kuitwa uye uko kunodiwa kupfeka kwakanyanya uye kusagadzikana kwekuora.Iyo ine yakanaka welding zvivakwa uye inogona kuvezwa neakajairika nzira dzewelding.Nekuda kwekuwedzera kwe molybdenum Mo element, 316 Stainless simbi yakavandudza zvakanyanya kuramba kwecorrosion uye yakakwirira tembiricha kuramba, basa rakanakisa kuomesa (kwete-magineti), uye kutaridzika kwezvigadzirwa zvinotonhora zvine gloss yakanaka.Kuenzaniswa ne304 simbi isina tsvina, kushanda kwechigadzirwa kwakagadziridzwa., mutengo wacho wakakwirira.Iye zvino, kushongedza kweimba kwakawanda uye kushongedza kwepamusoro-soro kwekutengeserana kuchashandisa 316 simbi isina tsvina, nekuda kwekudzivirira kwayo kwakasimba, hupenyu hwebasa huchawedzera kana huchienzaniswa ne304 simbi isina tsvina.
