S32750 Material Properties
2507 is super duplex stainless simbi ine nani corrosion resistance uye simba kudarika 2205. Inobatanidza zvinhu zvinobatsira zvakanyanya zveferritic uye austenitic steels uye, nekuda kwepamusoro chromium uye molybdenum content, ine kupikisa kwakanyanya kune yunifomu, pitting uye crevice corrosion.Iyo miviri-yechikamu chimiro inovimbisa kuti simbi ine yakakwirira kupikisa kushungurudza corrosion kuputika uye yakakwirira mechanical simba.
Iyo yepamusoro yemukati yechromium uye molybdenum inoita kuti ive nekuramba kwakasimba kune yakazara corrosion yeorganic acids senge formic acid, acetic acid, nezvimwewo, uye zvakare ine yakasimba corrosion resistance kune inorganic acids, kunyanya ayo ane chlorides.Kana ichienzaniswa ne904L, iyo yakanyatsogadzirirwa kurwisa pure sulfuric acid, 2507 ine simba rekusaita ngura kune diluted sulfuric acid yakasanganiswa ne chloride ions.
316L giredhi haigone kushandiswa munzvimbo yehydrochloric acid, inogona kunge iri pasi pekuora kwenzvimbo kana kupera kwese, nepo 2507 inogona kushandiswa mudiluted hydrochloric acid nharaunda, ine yakasimba anti-spot uye anti-crevice corrosion kugona.Iyo yakaderera kabhoni yemukati ye2507 inoderedza zvakanyanya njodzi yekunaya kwecarbide mu intergranular panguva yekupisa kupisa uye, nekudaro, inopikisa zvakanyanya kune carbide-inoenderana intergranular corrosion.
2507 ine yakakwira yekumanikidza simba, simba rekuita uye yakaderera kupisa kwekuwedzera coefficient uye yakakwirira yekupisa conductivity, hunhu uhwu hwakakodzera kune akawanda maumbirwo uye zvikamu zvemakanika.
2507 haifanirwe kuiswa munzvimbo yekushisa yakakwira kupfuura 300 ℃ kwenguva yakareba, izvo zvinogona kuderedza kuoma kwayo.
Corrosion Resistance Of S32750 Material
1. Corrosion resistance
Iyo yakakwira chromium uye molybdenum zvirimo zveSAF 2507 zvinoita kuti isanyanya kusimba mukuora kwakawanda kweorganic acids senge formic acid uye acetic acid.SAF 2507 alloy zvakare ine yakasimba kuramba kune inorganic acids, kunyanya ayo ane chlorides.corrosion resistance.
Kana ichienzaniswa ne904L, SAF2507 ine corrosion resistance yakasimba kune diluted sulfuric acid yakasanganiswa nechloride ions.904L is a alloy mu austenitic state, yakanyatsogadzirirwa kurwisa pure sulfuric acid corrosion.
316L giredhi haigone kushandiswa munzvimbo yehydrochloric acid, inogona kunge iri pasi pekuora kwenzvimbo kana kupera kwese.SAF2507 inogona kushandiswa mu dilute hydrochloric acid nharaunda, ine yakasimba anti-spot uye anti-crevice corrosion kugona.
2. Intergranular corrosion
Iyo yakaderera kabhoni yemukati yeSAF 2507 inoderedza zvakanyanya njodzi ye intergranular carbide kunaya panguva yekupisa, saka, iyi alloy inopikisa zvakanyanya kune carbide-inoenderana intergranular corrosion.
3. Stress corrosion cracking
Iyo duplex chimiro cheSAF 2507 inoita kuti isanyanya kushingirira kushungurudza corrosion kupaza.Nekuda kweiyo yepamusoro alloy yemukati, iyo corrosion kuramba uye simba reSAF 2507 zviri nani pane 2205.
Makatsemuka anenge asingadzivisike mukuvaka, nezvimwewo, izvo zvinoita kuti simbi isina tsvina iwedzere kutapukirwa nekuora munzvimbo dzechloride.SAF 2507 ine simba rakasimba rekuramba kukoromoka.Iyo isocorrosion curve yeSAF 2507 mu sulfuric acid ine 2000ppm chloride ions 0.1 mm / gore;isocorrosion curve mu hydrochloric acid 0.1 mm / gore.
S32205 Material Application Areas
2507 simbi isina tsvina inoshandiswa muindasitiri yemafuta uye gasi;offshore Shipotian oiri mapuratifomu (kupisa exchanger machubhu, kurapwa kwemvura uye masisitimu ekupa mvura, masisitimu ekudzivirira moto, masisitimu ekupfapfaidza mvura, masisitimu ekudzikamisa mvura; petrochemical equipment; desalination (desalination) midziyo (uye midziyo muHigh-pressure pombi, pombi dzemvura yegungwa); uye zvimiro zvemukati zvinoda zvese simba rakakwirira uye yakakwira corrosion kuramba; kupisa (kupedza) gasi rekuchenesa michina.
Mapaipi eindasitiri yemakemikari, midziyo, zvinopisa kupisa, mapaipi emvura yegungwa muzvidyarwa zvekubvisa salination, oiri negasi indasitiri yemidziyo, magetsi chirimwa flue gasi desulfurization masisitimu, zvekuwachisa, shongwe dzekunyudza, makemikari emvura matangi.
