Yog tias koj tab tom nrhiav qib ntawm stainless hlau nrog high corrosion tsis kam lossis hardness, koj tuaj yeem sib piv 440c stainless hlau. Ob qho tib si tau siv dav hauv kev lag luam thiab cov ntaub ntawv precision, tab sis lawv cov tshuaj lom neeg muaj tshuaj lom neeg, kev ua haujlwm zoo thiab corrosion tsis txawv.
Qhov twg stainless hlau muaj ntau dua corrosion tsis kam, 440c lossis 316L?
316L stainless hlau tau zoo dua corrosion tsis kam tshaj 440C. Qhov no yog vim 316L yog ib tug Austenitic stainless hlau uas muaj molybdenum stainless hlau uas ua ntej kev ua haujlwm hnyav thiab hnav tsis kam.

440C vs {{1} l stainless hlau: Kev siv tshuaj lom sib xyaw
440C muaj ntau cov ntsiab lus carbon ntau dua thiab tsawg dua npib / molybdenum, muab nws hardness hardness tab sis qis dua piv rau 316L.
Cov pa roj carbon qis thiab ntxiv Molybdenum ntawm 316L ua rau nws tiv taus ntau ntau ntxiv rau pitting thiab chloride nres, tshwj xeeb tshaj yog hauv marine thiab tshuaj ib puag ncig.

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 ncav cuag ib qho nyuaj ntawm txog 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 Hardness thiab cov kabmob thiab cov kabmob 316l yog qhov zoo rau nws cov kev ua tau zoo heev.
Puas muaj 440c siv tau hauv ib puag ncig marine?
Tsis pom zoo. 316L yog qhov kev xaiv zoo dua rau kev siv hauv dej hiav txwv lossis dej noo.
Uas kim dua, 440c lossis 316L stainless hlau?
440C feem ntau kim dua ib phaus vim nws cov pa roj carbon ntau, thaum 316L muaj cov nqi tshav kub lub neej vim nws qhov kev tawm tsam ntau dua rau kev xeb.
