Lub corrosion resistance ntawm GH4145 steel phaj yog ib qho ntawm nws qhov tseem ceeb ntawm nws ua kom zoo tsim cov tshuaj sib xyaw thiab ruaj khov microstructure. Qhov no tso cai rau nws ua kom ntseeg tau nyob rau ntau qhov chaw hnyav. Ntawm no yog cov ncauj lus kom ntxaws tawg ntawm nws corrosion tiv taus cov yam ntxwv:

1. Corrosion Resistance Ichanisms

Chromium (CR) kev pab: Nrog cov ntsiab lus chromium ntawm ib ncig ntawm 16%, GH4145 foos ib qho tuab thiab ruaj khov cov tshuaj oxide (cr₂o₃) passive zaj duab xis ntawm nws cov npoo thaum raug oxidizing ib puag ncig. Zaj yeeb yaj kiab no ua rau muaj kev tiv thaiv kev tiv thaiv, tiv thaiv kev tawm tsam ntxiv thiab corrosion ntawm cov hlau hauv qab.

Nickel (NI) Matrix Lub Luag Haujlwm: Cov ntsiab lus npib tsib xee (kwv yees li 56%) tau muab cov kev tiv thaiv kev xeb dav thiab alkaline. Nickel tseem txhim kho lub peev xwm los tswj nws cov yeeb yaj kiab passive hauv chloride hauv chloride-}} muaj kev pheej hmoo ntawm cov kev sib raug zoo hauv cheeb tsam.

Molybdenum (mo) txhim kho: Molybdenum (txog 8%) txhim kho cov alloy qhov tsis kam rau pitting thiab crevice corrosion, tshwj xeeb hauv chloride {}} rich nyiaj nplua nuj. Nws pab tswj cov yeeb yaj kiab passive thiab inhibits txoj kev loj hlob ntawm cov pits ntawm corrosion.

2. Kuj tsis muaj kev sib deev tshwj xeeb

High - kub oxidation tsis kam:
GH4145 Kev ua yeeb yam zoo oxidation tsis kam ntawm qhov kub txog li 980 degree. Cov kev sib xyaw ua ke ntawm chromium, npib tsib, thiab lwm cov ntsiab lus ua kom pom cov roj av txuas ntxiv mus rau lub siab ntev thiab txias thiab txias lossis kub. Qhov no ua rau nws haum rau cov khoom siv hauv ayer - colines thiab muaj kev muaj chaw ua haujlwm khiav tawm hauv high- cov pa oxidizing.

 

 

 

 

 

 

 

 

Tsis kam mus rau aqueous corrosion:

Nruab Nruab Nruab Nrab thiab Alkaline Solutions: Nws qhia tau zoo heev rau corrosion nyob rau hauv nruab nrab hauv nruab nrab, Chav, thiab feem ntau cov kev daws teeb meem hydroxide), nrog kev poob phaus hydroxide), nrog kev poob qis qis dhau los yog qhov tsis tshua muaj ntsej muag.

Chloride ib puag ncig: Hos tsis muaj zog rau chloride -}} Txoj kev corrosion, GH4145 muaj qhov zoo dua pittings, ua tsaug rau nws cov ntsiab lus molybdenum. It performs well in seawater, brines, and other chloride-containing media, though long-term exposure to highly concentrated chlorides may still require additional protective measures.
