Qhov sib txawv tseem ceeb ntawm 410 thiab 410S stainless hlau yog nyob rau hauv lawv cov ntsiab lus carbon thiab lawv cov ntawv thov.
410 stainless hlau yog cov hlau stainless hlau dav dav uas muaj tsawg kawg yog 11.5% chromium. Nws muaj kev tiv thaiv corrosion zoo, lub zog siab, thiab qhov nyuaj. Nws feem ntau siv rau hauv cov ntawv thov uas xav tau kev tiv thaiv corrosion nruab nrab thiab cov khoom siv kho tshuab siab, xws li cov li qub, twj tso kua mis, cov khoom siv txuas, thiab cov khoom siv rau kev lag luam roj av.
Ntawm qhov tod tes, 410S stainless hlau yog qhov hloov pauv qis-carbon ntawm 410 stainless hlau. Nws muaj cov ntsiab lus carbon qis dua (feem ntau nyob ib puag ncig 0.08%) piv rau 410 (0.15% siab tshaj). Cov ntsiab lus carbon txo qis txhim kho nws qhov weldability thiab ua rau nws tiv taus kev rhiab heev, uas yog kev tsim cov chromium carbides raws cov ciam teb ntawm cov noob uas tuaj yeem txo qhov kev tiv thaiv corrosion. Yog li ntawd, 410S zoo dua rau cov ntawv thov qhov twg xav tau vuam, xws li cov thawv annealing, cov khoom siv cua sov, thiab lwm yam kev siv kub siab.
Hauv kev xaus, qhov sib txawv tseem ceeb ntawm 410 thiab 410S stainless hlau yog cov ntsiab lus carbon thiab lawv cov ntawv thov. 410 yog cov hlau stainless hlau dav dav nrog cov ntsiab lus carbon ntau dua, thaum 410S yog cov pa roj carbon tsawg uas muaj kev txhim kho weldability thiab tiv taus kev sensitization.
