440C vs.316L Stainless Hlau: Corrosion Resistant
Tso lus
Yog tias koj tab tom nrhiav rau lub stainless hlau qib nrog siab corrosion tsis kam lossis hardensness, koj tuaj yeem sib piv rau hauv kev lag luam thiab cov tshuaj lom neeg, thiab corrosion tsis txawv heev.
Qhov twg stainless hlau yog ntau corrosion tiv taus, 440c lossis 316L?
316L stainless hlau tau zoo dua corrosion tsis kam tshaj 440C. Qhov no yog vim 316L yog ib qho tsis muaj pa stainless hlau uas muaj martas cov ntsiab lus nrog cov pa roj carless thiab hnav tsis kam hla corrosion tsis kam.

Qhov twg stainless hlau yog qhov nyuaj, 440C lossis 316L?
440C stainless hlau yog qhov nyuaj dua 316L stainless hlau. Tom qab kev kho cua sov, 440C tuaj yeem ua tiav qhov nyuaj ntawm ib puag ncig 58 txog 62 teev rau 62 teev (Rockwell C), thaum lub sijhawm 316L muaj qhov siab tshaj plaws ntawm 95 hrb (rockwell b). Qhov no ua rau 440C tsim nyog rau cov ntawv thov uas yuav tsum muaj lub siab hardness thiab coj tawm tsam, thaum 316l yog qhov haum rau nws qhov chaw hnyav.
Puas tuaj yeem 440C siv tau hauv cov chaw ua haujlwm marine?
Tsis pom zoo . 316 l yog qhov kev xaiv zoo dua rau kev siv hauv dej hiav txwv lossis dej noo noo.
Uas kim dua, 440c lossis 316L stainless hlau?
440C feem ntau kim dua ib phaus vim nws cov ntsiab lus muaj roj carbon ntau, thaum 316L muaj qis dua li lub neej vim nws txoj kev tiv thaiv tau qis dua.
