440 stainless hlau vs .3 cr13: corrosion tsis kam
PCR13 muaj qis dua chromium (~ 13%), muab ib nrab corrosion tsis kam-nplua rau sab hauv lossis qhuav ib puag ncig.
440A thiab 440C, nrog cov ntsiab lus chromium siab dua (~ 17%), tiv taus corrosion zoo dua, tshwj xeeb tshaj yog nyob rau hauv ntub dej, noo noo {}}
NCO TSEG: 440A muaj kev tiv thaiv corrosion zoo dua 440C vim nws cov ntsiab lus roj carbon ntau dua, txawm li 440c ua nyuaj {}}
Yog PC15 sib npaug rau 440A, 440b, lossis 440c?
PCR13 stainless hlau yog ze tshaj plaws hauv kev sib xyaw thiab kev ua tau rau Aisi 420A, tsis yog ib qho ntxiv rau cov ntsiab lus Chromium zoo sib xws (~ 0 {. 3%), Muab nws ntau dua lub zog thiab hnav tsis kam. 440 b thiab 440C muaj cov ntau dua cov roj carbon ntau dua thiab qib siab dua. Hauv cov ntsiab lus, PCC13 yog softer, tsawg dua hnav-resistant, thiab ntau dua cov neeg pheej yig, ua rau nws muaj txiaj ntsig zoo dua rau cov kev ua haujlwm siab thiab qhov chaw ua kom zoo.
🔸 Puas yog PCR13 stainless hlau zoo rau riam?
Yog, nws yog ib qho siv hauv cov nyiaj txiag-phooj ywg ntse, tab sis tsis muaj ntug kev tuav ntawm cov hlau ntau dua li 440c.
🔸 yog 3cr13 tib yam li 440A?
Tsis muaj {. 3 cr13, thaum lub sijhawm 440A muaj ntau dua carbon thiab chromium, muab zoo dua hardness thiab corrosion tsis kam .
UAS yog qhov zoo dua: 440C lossis PC13?
440C is better in terms of hardness, wear resistance, and edge retention. Use it for performance-critical applications. Choose 3Cr13 for low-cost tools with moderate performance needs.
