Yuav ua li cas pom weld stainless hlau thiab tooj liab?

Stainless hlau yog ib lo lus dav dav rau stainless hlau thiab acid resistant steel. Stainless hlau, tseem hu ua austenitic, martensitic, thiab ferritic stainless hlau, hais txog cov hlau uas tiv taus cov xov xwm tsis muaj zog xws li cua, chav, thiab dej, thaum acid resistant steel hais txog cov hlau uas tiv taus cov tshuaj corrosive media xws li acid, alkali, thiab ntsev.
Muaj qhov sib txawv tseem ceeb hauv qib ntawm alloying ntawm stainless hlau thiab acid resistant steel. Stainless hlau tej zaum yuav tsis acid resistant; Acid resistant steel feem ntau muaj xeb kuj.
Cov xeb tsis kam thiab corrosion kuj ntawm stainless hlau yog feem ntau yog vim lub ntsiab chromium cov ntsiab lus, uas muaj peev xwm tsim ib tug chromium nplua nuj oxide zaj duab xis (passivation zaj duab xis) nyob rau saum npoo ntawm cov hlau. Yog li, cov ntsiab lus chromium hauv stainless hlau yuav tsum siab dua 12%.
Thaum tshav kub kub resistant steel yog hais txog cov hlau uas muaj peev xwm tswj tau cov tshuaj stability (corrosion resistance, non oxidation) thiab muaj zog txaus ntawm qhov kub thiab txias.
Lub tshav kub tsis kam ntawm cov hlau yog tsuas yog ua tiav los ntawm kev sib tsoo, thiab nws tuaj yeem muab faib ua cov hlau tsis tshua muaj cua sov-resistant steel raws li nws cov ntsiab lus alloy; Muaj peb pawg loj: nruab nrab alloy kub-resistant steel thiab siab alloy kub-resistant steel. Tsawg alloy kub-resistant steel hais txog cov cua sov-resistant steel nrog cov ntsiab lus alloying tsawg dua 5%; Nruab nrab alloy tshav kub-resistant steel hais txog cov cua kub-resistant steel nrog cov ntsiab lus alloying ntawm 5% ~ 12%; High alloy kub hlau yog hais txog cov cua kub-resistant steel nrog cov ntsiab lus alloying ntau dua 13%. Lub tshav kub-resistant steel hais nyob rau hauv phau ntawv no tsuas yog high alloy kub-resistant steel, thiab tsis koom nrog tsawg alloy los yog nruab nrab alloy kub-resistant steel.
Lub ntsiab tseem ceeb ntxiv rau cov hlau tsis muaj cua sov yog chromium, thiab cov ntsiab lus chromium feem ntau yog ntau dua 12%, uas yog tib yam li stainless hlau. Yog li ntawd, hom hlau no muaj ob qho tib si kub tsis kam, xeb kuj, thiab corrosion kuj. Yog li ntawd, ntau hom cua sov-resistant steel kuj yog stainless hlau. Qee cov neeg xa mus rau cov hlau tsis muaj cua sov no xws li cov hlau tsis muaj cua sov, thiab cov hlau tsis xeb tau hais ua ntej los ntawm cov hlau tsis xeb hlau, kuj tseem hu ua stainless hlau, thiab ntau lub sijhawm (xws li hauv cov khoom siv vuam) , lawv tau sau npe hu ua stainless hlau.
Lub melting kub ntawm stainless hlau ntawm 1500 degrees yog dab tsi? Lub melting kub ntawm tooj liab yog nyob ib ncig ntawm 1100 degrees. Vim muaj qhov muaj zog kub tsis kam thiab siab hluav taws xob tiv thaiv ntawm stainless hlau, qhov nruab nrab zaus qhov chaw vuam tshuab vuam txoj kev tuaj yeem siv tau.
Qhov ceev tam sim no thiab cua kub ceev ntawm qhov nruab nrab zaus qhov chaw vuam tshuab tuaj yeem ua tiav vuam sai.
Muaj lwm txoj hauv kev yooj yim rau welding stainless hlau thiab tooj liab xaim ua ke:
Ua ntej, npaj qee cov kua qaub: tsuas yog ob peb milliliters ntawm dilute hydrochloric acid (Hcl + H2O) thiab muab tso rau hauv lub raj mis me me; Tso lub roj teeb manganese zinc qhuav, siv ob peb square millimeters ntawm nws cov tawv nqaij grey zinc txheej, muab tso rau hauv dilute hydrochloric acid, pib foaming, thiab tos ib nrab ib teev ua ntej yuav siv tau.
Thib ob, siv cov tshuaj txhuam hniav kom tau qee cov kua qaub thiab siv rau qhov chaw uas cov hlau yuav tsum tau welded rau ntawm cov hlau tsis muaj steel,
Thib peb, siv lub tshuab hluav taws xob siv hluav taws xob los siv cov khoom siv rau cov cheeb tsam nrog cov kua qaub, kom nws nkag mus rau hauv tag nrho.
Fourthly, nws tsis yog nyuaj rau solder lub soldered hlau taub hau rau nws.
Cov txheej txheem vuam saum toj no tuaj yeem ua rau txhua qhov vuam stainless hlau thiab tooj liab hlau ua ke, nyob ntawm txoj haujlwm thiab kev xaiv cov txheej txheem tsis
Weld stainless hlau daim hlau thiab tooj liab daim hlau.
Nco ntsoov xaiv lub tshuab jaxo vuam thaum yuav lub tshuab vuam tshuab!
