254SMo Material Properties
254SMO is an austenitic Stainless simbi.Nekuda kweiyo yakakwira molybdenum yemukati, ine yakanyanyisa kupikisa kugomba uye crevice corrosion.Iri giredhi resimbi isina tsvina rakagadzirwa uye rakagadziridzwa kuti rishandiswe munzvimbo dzine halide dzakaita semvura yegungwa.254SMO zvakare ine kuramba kwakanaka kune yunifomu ngura.Kunyanya mu halide-ine acids, simbi inokwirisa kupfuura yakajairwa Stainless simbi.C yayo ine<0.03%, saka inonzi pure austenitic stainless simbi (<0.01% inonziwo super austenitic Stainless simbi).Super Stainless simbi imhando yesimbi yakakosha.Chokutanga pane zvose, zvakasiyana kubva kune yakajairwa Stainless simbi mukugadzirwa kwemakemikari.Inoreva alloy yakakwira simbi isina tsvina ine yakakwira nickel, yakakwira chromium uye yakakwira molybdenum.Pakati pazvo, iyo inonyanya kuzivikanwa ndeye 254SMo ine 6% Mo. Iri rudzi rwesimbi ine yakanaka kwazvo yekusagadzikana kwenzvimbo, uye ine yakanaka pitting corrosion resistance (PI≥40) uye Iine zviri nani kushushikana kwekuora mwoyo uye inotsiva Ni- based alloys uye titanium alloys.Chechipiri, maererano nekupisa tembiricha kuramba kana kuonda kuramba, ine zvirinani kupisa tembiricha kana corrosion resistance, iyo isingatsivike 304 simbi isina tsvina.Uye zvakare, kubva muchikamu chesimbi isina tsvina, iyo metallographic chimiro cheyakakosha simbi isina tsvina ndeye yakagadzika austenite metallographic chimiro.
Sezvo iyi yakakosha simbi isina tsvina iri yakakwirira-alloy zvinhu, maitiro ekugadzira akaomarara.Kazhinji, vanhu vanogona kungovimba nemaitiro echinyakare kugadzira iyi yakakosha simbi, senge infusion, forging, rolling uye zvichingodaro.
254SMo Material Application Areas
1. Ocean: zvimiro zvemugungwa munzvimbo yegungwa, kuchenesa mvura yegungwa, mvura yegungwa yemvura yegungwa, kupisa kwemvura yegungwa, nezvimwe.
2. Munda wekuchengetedzwa kwezvakatipoteredza: flue gasi desulfurization mudziyo wemagetsi ekupisa, kurapwa kwemvura yetsvina, nezvimwe.
3. Simba remagetsi: kugadzirwa kwemagetsi enyukireya, kushandiswa kwakakwana kwemarasha, kugadzirwa kwemagetsi egungwa, nezvimwewo.
4. Petrochemical munda: kucheneswa kwemafuta, makemikari uye makemikari midziyo, nezvimwe.
5. Munda wekudya: kugadzira munyu, kubika soy sauce, nezvimwe.
6. High-concentration chloride ion environment: indasitiri yemapepa, michina yakasiyana-siyana yebleaching
