Pfupiso yeDuplex Stainless Steel

Simbi isina tsvina yeSuper duplex inosiyaniswa nesimbi yakajairika yeduplex nekuda kwehunhu hwayo hwakavandudzwa zvikuru hunodzivirira ngura. Isimbi yakabatanidzwa zvakanyanya ine huwandu hwakawanda hwezvinhu zvinodzivirira ngura zvakaita sechromium (Cr) uye molybdenum (Mo). Simbi isina tsvina yeSuper duplex, S32750, ine 28.0% chromium, 3.5% molybdenum, uye 8.0% nickel (Ni). Izvi zvikamu zvinodzivirira zvakanyanya ngura, zvinosanganisira acids, chlorides, uye caustic solutions.

Kazhinji, simbi dzisina ngura dzakasimba dzinobva pamhando mbiri dzesimbi dzinobva pamhando mbiri dzesimbi dzine kugadzikana kwakawedzerwa kwemakemikari. Izvi zvinoita kuti ive mhando yakanaka yekugadzira zvinhu zvakakosha muchikamu chemafuta, zvakaita sezvishandiso zvinochinja-chinja kupisa, mabhoyira, uye michina yemidziyo yepressure.

Kupatsanurwa kweSimbi Isina Kusimba yeDuplex

l Rudzi rwekutanga imhando yealloy yakaderera, ine giredhi rinomiririra reUNS S32304 (23Cr-4Ni-0.1N). Simbi haina molybdenum, uye kukosha kwePREN i24-25. Inogona kushandiswa pachinzvimbo cheAISI304 kana 316 mukudzivirira ngura.

Rudzi rwechipiri nderwemhando yepakati, rudzi rwunomiririra ndiUNS S31803 (22Cr-5Ni-3Mo-0.15N), kukosha kwePREN i32-33, uye kuramba kwayo ngura kuri pakati peAISI 316L ne6% Mo+N austenitic stainless steel.

Rudzi rwechitatu nderwemhando yepamusoro yesimbi, iyo inowanzo kuve ne25% Cr, molybdenum nenitrogen, uye dzimwe dzinewo mhangura netungsten. Rudzi rwemhando yeUNSS32550 (25Cr-6Ni-3Mo-2Cu-0.2N), PREN value i38-39, uye kuramba ngura kwerudzi urwu rwesimbi kwakakwira kupfuura kwe22% Cr duplex stainless steel.

Rudzi rwechina isimbi isina ngura ine duplex, ine molybdenum yakawanda uye nitrogen. Chiyero chakajairika iUNS S32750 (25Cr-7Ni-3.7Mo-0.3N), uye mimwe ine tungsten nemhangura. Kukosha kwePREN kwakakura kupfuura 40, iyo inogona kushandiswa mumamiriro epakati akaoma. Inodzivirira ngura zvakanaka uye ine hunhu hwakakwana hwemakanika, izvo zvinogona kuenzaniswa nesimbi isina ngura ine super austenitic.

Mabhenefiti eSimbi Isina Kusimba yeDuplex

Sezvambotaurwa pamusoro apa, Duplex inowanzoita zviri nani pane mhando dzesimbi dzinowanikwa mukati mayo. Zviri nani kutaura kuti, kusanganiswa kwehunhu hwakanaka hunobva kuaustenite neferrite zvinhu zvinopa mhinduro iri nani kune akawanda mamiriro akasiyana ekugadzira.

l Hunhu hwekudzivirira ngura – Mhedzisiro yemolybdenum, chromium, uye nitrogen pakudzivirira ngura kweDuplex alloys yakakura kwazvo. MaDuplex alloys akawanda anogona kuenzana uye kupfuura mashandiro ekudzivirira ngura emhando dzakakurumbira dze austenitic dzinosanganisira 304 na316. Anonyanya kushanda pakurwisa ngura yakatsemuka uye inopinda mugomba.

l Kupwanyika kwengura yestress – SSC kunokonzerwa nezvinhu zvakasiyana-siyana zvemumhepo – tembiricha nehunyoro ndizvo zvinonyanya kuoneka. Kupwanyika kwesimba re tensile kunongowedzera dambudziko. Magiredhi enguva dzose e austenitic anogona kupwanyika nengura yestress – Duplex stainless steel haisiyo.

Kusimba - Duplex yakasimba kupfuura simbi dze ...

Simba - Masimbi maviri anogona kusimba kanosvika kaviri kupfuura austenitic neferritic structures. Simba rakawanda rinoreva kuti simbi inoramba yakasimba kunyangwe ukobvu hwayo hushoma izvo zvinonyanya kukosha pakuderedza huremu.
