Stainless hlau phaj kev ua tau zoo: corrosion kuj

Stainless hlau muaj kev tiv thaiv corrosion zoo ib yam li cov tsis ruaj khov nickel-chromium alloy 304. Cov cua kub ntev hauv qhov kub ntawm chromium carbide degrees yuav cuam tshuam rau alloys 321 thiab 347 hauv cov xov xwm hnyav corrosive. Feem ntau yog siv rau hauv cov ntawv thov kub, cov khoom siv yuav tsum muaj qhov muaj zog tiv thaiv kom tsis txhob muaj kev cuam tshuam los ntawm intergranular corrosion ntawm qhov kub thiab txias.

kub kub oxidation kuj

Stainless hlau daim hlau yog resistant rau kub oxidation, tab sis tus nqi oxidation yuav cuam tshuam los ntawm inherent yam xws li raug ib puag ncig thiab cov khoom zoo.

lub cev muaj zog

Tag nrho cov tshav kub hloov coefficient ntawm cov hlau yog nyob ntawm lwm yam uas tsis yog thermal conductivity ntawm hlau. Feem ntau, qhov kub dissipation coefficient ntawm zaj duab xis, oxide nplai thiab qhov chaw ntawm cov hlau. Stainless hlau ua kom lub ntsej muag huv si, yog li nws ua kom sov zoo dua li lwm cov hlau uas muaj thermal conductivity ntau dua. Liaocheng Suntory Stainless Steel Regulations 8. Technical Standards for Stainless Steel Phaj High-strength stainless hlau daim hlau nrog zoo heev corrosion kuj, dabtsi yog khoov workability, toughness ntawm welded qhov chaw, thiab stamping workability ntawm welded qhov chaw thiab lawv txoj kev tsim. Tshwj xeeb, muaj C: 0.02% lossis tsawg dua, N: 0.02% lossis tsawg dua, Cr: 11% lossis ntau dua thiab tsawg dua 17%, tsim nyog muaj Si, Mn, P, S, Al, Ni, thiab txaus siab 12≤Cr Mo 1.5Si≤17. Thaum tshav kub kub ntawm stainless hlau phaj nrog 1≤Ni 30 (CN) 0.5 (Mn Cu) ≤4, Cr 0.5 (Ni Cu) 3.3Mo≥16.0, 0.006≤CN≤0.030 txog 850 ~ 1250 ℃, thiab tom qab ntawd kub rau 1 ℃ / s los yog ntau tshaj qhov cua txias cua txias kev kho cua sov. Nyob rau hauv txoj kev no, nws tuaj yeem dhau los ua lub zog siab stainless hlau phaj, uas nws cov qauv muaj ntau dua 12% martensite ntim, muaj lub zog siab ntau dua 730MPa, corrosion resistance thiab dabtsi yog khoov kev ua tau zoo, thiab muaj qhov zoo heev toughness nyob rau hauv lub vuam kub-tsim cheeb tsam. Kev rov siv dua ntawm Mo, B, thiab lwm yam tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov khoom welded.

Cov pa taws thiab cov pa taws tsis tuaj yeem txiav cov hlau tsis muaj steel vim tias cov hlau tsis muaj oxidized yooj yim.
