Stainless hlau 304/316L / 321 Qhov txawv

Stainless hlau 304/316L / 321 sib txawv

304 thiab 316 stainless hlau sib txawv

Qhov tseeb, nrog lub qhov muag liab qab tsis tuaj yeem pom qhov txawv ntawm 304 thiab 316 stainless hlau, ntau tus neeg pom cov duab no tsis meej pem, hnub no nrog kuv mus saib qhov txawv ntawm 304 thiab 316 stainless hlau.

Ua ntej ntawm tag nrho cov, 316 stainless hlau muaj Mo, uas yog zoo corrosion kuj tshaj 304 stainless hlau nyob rau hauv qhov kub thiab txias ib puag ncig, yog li nyob rau hauv kub kub, engineers feem ntau xaiv qhov chaw ntawm 316 cov ntaub ntawv.

Qhov thib ob, kuj tseem muaj qhov sib txawv ntawm ob qho tib si los ntawm hom; 304 stainless hlau sib raug rau Suav hom 0Cr18Ni9; 316 stainless hlau sib haum rau Suav qib 0Cr17Ni12Mo2.

Qhov thib peb, 316 feem ntau txo cov ntsiab lus Cr, nce Ni cov ntsiab lus thiab nce Mo2% ~ 3%. Yog li, nws cov corrosion kuj muaj zog dua 304, haum rau kev siv tshuaj, dej hiav txwv thiab lwm qhov chaw, zoo ib yam, 316 tus nqi siab dua 304, 316 feem ntau yog siv rau hauv cov chaw uas muaj kev xav tau siab dua, los hloov 304.

Qhov tseeb, nrog lub qhov muag liab qab tsis tuaj yeem pom qhov sib txawv ntawm stainless hlau 304 thiab 316, muaj ntau txoj kev paub txog kev txheeb xyuas, kev siv cov tshuaj tsis muaj steel hlau rau kev txheeb xyuas, thov nyem qhov no mus saib.
