Lub tswv yim rau xaiv stainless hlau hluav taws xob cua sov yeeb nkab raw khoom

(1, txoj cai xaiv ntawm cov kav dej: kub tsis kam, corrosion kuj

2. Kev xaiv cov hlau tsis kam.

Stainless hlau 303 khoom, vim hais tias nws muaj leej faj, yog ib qho yooj yim mus txiav, feem ntau yog siv rau kev txiav yooj yim thiab siab xav tau rau stainless hlau nto tiav.

Ntawm cov xwm txheej uas cuam tshuam rau qhov zoo ntawm stainless hlau hluav taws xob cua sov kav, qhov zoo ntawm cov ntaub ntawv yog ib qho tseem ceeb vim li cas. Tsim nyog xaiv cov ntaub ntawv raw rau cov kav hluav taws xob cua sov yog qhov tsim nyog los xyuas kom meej qhov zoo ntawm cov kav hluav taws xob cua sov. Kev xaiv cov ntaub ntawv suav nrog cov ntsiab lus hauv qab no rau kev siv:

Piv nrog stainless hlau 304, stainless hlau 304L muaj cov ntsiab lus qis dua. Cov hlau tsis muaj carbon tsawg muaj tsawg carbides decomposed los ntawm thermal cuam tshuam ze ntawm lub vuam thaum vuam, yog li nws txo cov pa roj carbon monoxide, vim carbides yuav ua rau vuam corrosion. . Qib 305 muaj cov ntsiab lus npib tsib xee ntau dua thiab yooj yim dua rau kev tsim vim nws qhov qis ua haujlwm hardening. Stainless hlau 308 cov khoom siv feem ntau yog siv los tsim cov electrodes.

3. Kev xaiv ntawm magnesium oxide hmoov.

4. Kev xaiv cov khoom sib khi. Thawj stainless hlau 301 khoom, thaum deformed thaum lub sij hawm ua, muaj ib tug hardening tshwm sim thiab yog siv nyob rau hauv ntau yam muaj zog lub sij hawm. Nyob rau hauv cov txheej txheem ntawm kev tsim stainless hlau cua sov yeeb nkab, stainless hlau 304 khoom yog siv, uas yog dav siv nyob rau hauv cov cua kub kua (tsis muaj zog acid thiab alkali) thiab cua cua sov. Nws muaj kev ua haujlwm zoo, yooj yim rau kev tsim thiab tus nqi nruab nrab. siv hauv kev tsim khoom

Stainless hlau 302 cov khoom yog qhov tseeb ntau yam nrog cov ntsiab lus siab dua li 304, thiab muaj zog dua tom qab txias dov.
