Lub durability ntawm carbon steel tus kheej -tapping inserts nyob ntawm tej daim ntawv thov ib puag ncig thiab ua hauj lwm tej yam kev mob. Thaum lawv muaj qhov zoo ntawm kev hnav tsis kam, lawv muaj qhov tsis zoo hauv kev tiv thaiv corrosion; Yog li ntawd, lawv "durability" yog txheeb ze.
Zoo hnav tsis kam: Lub hardness ntawm carbon steel tuaj yeem nce los ntawm kev nce cov ntsiab lus carbon. Qee qhov siab - carbon steels tuaj yeem ncav cuag qhov hardness ntawm HRC50-60, uas ua rau lawv zoo dua rau cov hlau tsis zoo tib yam (xws li 304 stainless hlau, nws qhov hardness feem ntau tsawg dua lossis sib npaug rau HRC20) hauv kev tiv thaiv cov khoom cuam tshuam thiab kev sib txhuam. Nyob rau hauv ib puag ncig qhuav tsis muaj corrosive cov ntaub ntawv, carbon steel inserts tuaj yeem tswj tau lub neej ntev.
Tus nqi qis: Cov pa roj carbon hlau tau yooj yim thiab yooj yim rau kev ua, ua rau tag nrho cov nqi qis dua cov hlau tsis muaj steel. Nws tsim nyog rau kev siv nyiaj - txwv, luv- siv sijhawm, lossis tsis yog - cov khoom tseem ceeb.
Tsis zoo corrosion kuj: Carbon steel feem ntau yog tsim los ntawm hlau thiab carbon, uas yuav luag tsis muaj corrosion{0}} tiv taus cov ntsiab lus xws li chromium thiab npib tsib xee. Nyob rau hauv qhov chaw ntub dej los yog thaum sib cuag nrog cov khoom uas muaj chloride ions (xws li poov tshuaj chloride thiab ammonium chloride) los yog acidic Cheebtsam, nws yog heev raug rau electrochemical corrosion, ua xeb. Qhov no ua rau txo qis lub zog, xov puas, thiab txawm tias cov khoom xau lossis ua haujlwm tsis zoo.
Kev vam khom rau saum npoo: txhawm rau txhim kho corrosion kuj, carbon steel inserts feem ntau xav tau kev kho saum npoo xws li galvanizing, pleev xim, lossis chrome plating. Txawm li cas los xij, cov txheej txheem no tau yooj yim puas nyob rau hauv ntev - kev sib txhuam thiab kev cuam tshuam. Ib zaug puas lawm, corrosion kis tau sai heev, yuav tsum tau saib xyuas tsis tu ncua; txwv tsis pub, lawv lub neej yuav luv luv.
