Sehlahisoa sa Austentite Stainless Steel Investment Casting

Tšepe e sa hloekang e na le bonyane ba chromium ea 10.5%, e etsang hore e khone ho mamella maemo a mokelikeli a senyang le ho oxidation. Ha e khone ho senya 'me ha e senyehe, e fana ka bokhoni bo botle ba ho sebetsa, 'me e tsebahala haholo ka ponahalo ea eona e ntle. Mehaho ea matsete a tšepe e sa jeleng paate "e hana ho bola" ha e sebelisoa libakeng tse mokelikeli le mouoane o ka tlase ho 1200°F (650°C) le "tse thibelang mocheso" ha li sebelisoa ka holimo ho mocheso ona.

Austenitic tšepe e sa hloekange bua ka tšepe e sa hloekang e nang le sebopeho sa austenitic mocheso oa kamore. Austenitic stainless steel ke e 'ngoe ea lihlopha tse hlano tsa tšepe e sa hloekang ka sebopeho sa kristale (hammoho le ferritic, martensitic, duplex le pula e thata). Libakeng tse ling, tšepe e sa hloekang ea austentite e boetse e bitsoa 300 series stainless steel. Ha tšepe e na le hoo e ka bang 18% Cr, 8% -25% Ni, le hoo e ka bang 0.1% C, e na le mohaho o tsitsitseng oa austenite. Austenitic chromium-nickel tšepe e sa hloekang e kenyelletsa tšepe e tummeng ea 18Cr-8Ni le tšepe e phahameng ea Cr-Ni e ntlafalitsoeng ka ho eketsa litaba tsa Cr le Ni le ho eketsa Mo, Cu, Si, Nb, Ti le likarolo tse ling motheong ona. Austenitic stainless steel ha e na makenete ebile e na le boima bo phahameng le polasetiki, empa matla a eona a tlase, 'me ha ho khonehe ho e matlafatsa ka phetoho ea mohato. E ka matlafatsoa feela ke ho sebetsa ka serame. Haeba likarolo tse kang S, Ca, Se, Te li eketsoa, ​​​​e na le thepa e ntle ea machinability.

Austenitic stainless steel e ka boela ea hlahisa li-castings. E le ho ntlafatsa metsi a tšepe e qhibilihisitsoeng le ho ntlafatsa ts'ebetso ea ho lahla, motsoako oa alloy oa tšepe ea tšepe o lokela ho lokisoa ka ho eketsa silicon, ho atolosa mefuta e mengata ea chromium le nickel content, le ho eketsa moeli o ka holimo oa ntho e sa hloekang sebabole.

Austenitic tšepe e sa hloekang e lokela ho ba le tharollo e tiileng pele e sebelisoa, e le ho eketsa tharollo e tiileng ea li-precipitates tse fapaneng tse kang carbides ka har'a matrix a austenite, ha e ntse e etsa homogenizing sebopeho le ho felisa khatello ea maikutlo, e le ho etsa bonnete ba hore ho hanyetsa Corrosion ho matla le ho feta. thepa ea mochine. Sistimi e nepahetseng ea kalafo ea tharollo ke ho pholisa metsi ka mor'a ho futhumatsa ka 1050～1150℃ (likarolo tse tšesaane le tsona li ka pholile moea). Mocheso oa phekolo ea tharollo o itšetlehile ka tekanyo ea motsoako oa tšepe: Molybdenum-free kapa low-molybdenum tšepe limaraka li lokela ho ba tlaase (≤1100 ℃), le limaraka tse phahameng tsa alloyed tse kang 00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, joalo-joalo li lokela ho ba holimo ( 1080～1150) ℃).

Letlapa la tšepe la Austenitic 304, leo ho thoeng le tlisa matla a ho thibela mafome le ho hanyetsa ho bola, 'me le na le polasetiki e ntle haholo le e thata, e loketseng ho hatakela le ho theha. Ka boima ba 7.93 g / cm3, 304 tšepe e sa hloekang ke tšepe e sa hloekang e tloaelehileng haholo, e tsejoang hape e le 18/8 tšepe e sa hloekang indastering. Lihlahisoa tsa eona tsa tšepe li hanyetsa mocheso o phahameng 'me li na le thepa e ntle ea ho sebetsa, kahoo li sebelisoa haholo indastering le liindasteri tsa mokhabiso oa thepa ea ka tlung le indastering ea lijo le ea bongaka.
