Hunhu hweindasitiri yesimbi isina simbi mapaipi emhando dzakasiyana siyana

Izvo zvinofanirwa kutaurwa kuti ese austenitic Stainless simbi emvura pombi ane hunhu hwekupokana kwecorrosion, kupisa kwekushisa kwepamusoro uye kupikisa kwakanyanya.Kungotaura chete, vane maitiro akasiyana akajeka uye mabasa:

304: Yakajairika corrosion kuramba uye tembiricha inodzivirira Stainless simbi isina musono pombi, 304 ine yakanaka kuramba kune intergranular corrosion, yakanakisa corrosion kuita, kutonhora kushanda uye kuita chidhindo, uye inogona kushandiswa sesimbi inodzivirira kupisa.Panguva imwecheteyo, michina yesimbi ichiri yakanaka pa -180 ° C.Munzvimbo yakasimba yekugadzirisa, simbi ine plastiki yakanaka, kuoma uye kutonhora kushanda;ine yakanaka corrosion resistance mune oxidizing acids, mhepo, mvura uye mamwe midhiya.

304L mutsauko we304 simbi isina tsvina ine yakaderera kabhoni yemukati uye inoshandiswa panodiwa welding.Iyo yakaderera kabhoni yemukati inoderedza kunaya kwecarbides munzvimbo yakakanganiswa nekupisa pedyo neweld, izvo zvinogona kutungamirira kune intergranular corrosion (weld attack) mumasimbi asina tsvina mune dzimwe nzvimbo.

Iyo 316/316L yekupokana nekuora kwepombi yesimbi isina simbi iri nani pane iyo 304 pombi yesimbi isina tsvina, uye ine yakanaka inodzivirira mukuora mukugadzirwa kwe pulp nebepa.Nekuda kwekuwedzera kweMo, ine yakanakisa corrosion kuramba, kunyanya pitting kuramba;kusimba kwekushisa kwakanyanya zvakare kwakanaka kwazvo;basa rakanakisa kuomesa (kusasimba magineti mushure mekugadzirisa);isiri-magnetic mune yakasimba mhinduro mamiriro.Iyo inewo kupikisa kwakanaka kune chloride corrosion, saka inowanzoshandiswa munzvimbo dzemugungwa kana mapurojekiti ekuvaka pagungwa.

321 Stainless simbi iNi-Cr-Ti type austenitic Stainless Stainless steel industry pombi, kuita kwayo kwakada kufanana ne304, asi nekuda kwekuwedzerwa kwesimbi titanium, ine zvirinani intergranular corrosion resistance uye kusimba kwekushisa kwepamusoro.Nekuda kwekuwedzerwa kwesimbi titanium, inonyatso kudzora kuumbwa kwechromium carbide.321 simbi isina tsvina ine yakanakisa tembiricha yekumanikidza kutsemuka (Stress Rupture) kuita uye yakanyanya tembiricha creep kuramba (Creep Resistance) stress mechanical zvivakwa zviri nani pane 304 Stainless simbi.Ti mu 321 Stainless simbi pombi iripo sechinhu chinodzikamisa, asi zvakare igiredhi resimbi rinopisa, iro riri nani kupfuura 316L maererano nekupisa kwakanyanya.Iyo ine yakanaka corrosion resistance mu organic uye inorganic acids emhando dzakasiyana uye tembiricha, kunyanya muoxidizing media, uye inoshandiswa kugadzira linings nemapaipi ekupfeka-inodzivirira asidhi midziyo uye inopfeka-inodzivirira midziyo.Iyo ine kumwe kupikisa kwekushisa kwakanyanya, kazhinji kutenderedza 700 madhigirii, uye inowanzoshandiswa mumagetsi emagetsi.Inoshandiswa kumichina yemumunda mumaindasitiri emakemikari, marasha uye petroleum inoda kupikisa zvakanyanya kugadzika kwezviyo, zvikamu zvinodzivirira kupisa zvezvivakwa zvekuvaka uye zvikamu zvakaoma kupisa.

310S: Iyo inonyanya kushandiswa oxidation kuramba, ngura kuramba, tembiricha inodzivirira maindasitiri esimbi isina musono pombi uye maindasitiri welded pombi.Kushandiswa kwakajairwa: zvishandiso zvechoto, zvinhu zvemidziyo yekuchenesa mota.310S Stainless simbi pombi is an austenitic chromium-nickel simbi ine yakanakisa yepamusoro tembiricha oxidation kuramba, asidhi uye alkali kuramba, uye corrosion resistance.Nekuda kweiyo yepamusoro yemukati yechromium (Cr) uye nickel (Ni), ine zvirinani simba rekukambaira.Inogona kushanda nguva dzose pakupisa kwepamusoro uye ine yakanaka yakakwirira tembiricha kuramba.Kana kutonhora kuchipfuura 800, inotanga kupfava, uye kushushikana kunobvumirwa kunotanga kuderera nguva dzose.Iyo yakanyanya tembiricha yesevhisi ndeye 1200 ° C, uye kuenderera kwekushandisa tembiricha i1150 ° C.Mapaipi esimbi anodzivirira tembiricha anonyanya kushandiswa mukugadzira machubhu echoto chemagetsi uye zvimwe zviitiko.Mushure mekuwedzera iyo kabhoni yemukati mune austenitic simbi isina tsvina, iyo simba inovandudzwa nekuda kweiyo yakasimba mhinduro yekusimbisa maitiro.Iko kemikari yeaustenitic simbi isina tsvina yakavakirwa pachromium uye nickel.Zvinhu zvakadai se molybdenum, tungsten, niobium uye titanium zvinowedzerwa sehwaro.Nekuda kwekuti sangano rayo rakaita kumeso-centered cubic structure, rine simba repamusoro uye simba rekukambaira pakupisa kwepamusoro.
