Ntxiv nrog rau kev ua haujlwm zoo corrosion, ntxiv rau cov chromium thiab molybdenum rau lub alloy txhim kho nws lub dim.
Cov txhuas alloy muaj cov yam ntxwv hauv qab no: 1. Nws muaj cov tshuaj zoo corrosion tsis kam rau feem ntau cov tshuaj corrosive hauv qab ob qho kev mob ntawm cov pa oxidation thiab kho. Úit muaj kev tsis kam zoo rau pitting corrosion, void corrosion thiab intergranular corrosion. Cov ntsiab lus ntau dua ntawm MO thiab CR ua rau aluminium alloy resistant rau corrosion los ntawm corrosion los ntawm corroside ion cov ntsiab lus, thiab cov w sij hawm ntxiv txhim kho cov corrosion tsis kam. Nyob rau tib lub sijhawm, haastelloy c-276 aluminium alloy yog ib qho ntawm cov khoom raw ntub uas tiv thaiv cov chlorine ntub, hypochlorite thiab chlorine dioxide solutions. Ester daws tau pom meej corrosion tsis kam. Nws yog ib qho ntawm ob peb cov khoom siv raw uas tuaj yeem siv ua qhov kub sulfuric acid noo noo.
Cov pa roj carbon daim ntawv tuaj yeem yog cov hlau carbide lossis alloy steel f9 weld caj dab caj dab tuaj yeem yog carbide ntawm kev sib xyaw ua ke, piv txwv li, titanium. A182 F9 Steel plam ntawm cov flanges yog qhov zoo rau siv nrog cov kav dej seamless vim tias cov kav dej tso rau lawv rau qhov chaw ncaj qha rau kev sib txuas.

Lub tsevStainless hlau yeeb nkab & rajAlloy Steel yog hlau uas tau sib xws nrog ntau yam ntawm cov ntsiab lus hauv 1.0% thiab 50% los ntawm qhov hnyav los txhim kho nws cov khoom siv. Alloy cov hlau tawg tau tawg rau ob pawg: cov hlau qis thiab cov hlau loj. Qhov sib txawv ntawm ob yog kev sib cav. Smith thiab Hashemi txhais tau qhov sib txawv ntawm 4.0%, thaum degarmo, li al., Txhais tau nws ntawm 8.0%. [1] Feem ntau, cov kab lus "alloy steel" yog hais txog tsawg-alloy steels.
Alloy Steel Kave yog siv rau qhov kub thiab txias thiab kub tsawg (tsawg kub) hauv kev siv hluav taws xob, lossis rau cov ntawv thov siab heev. ASTM A335 Alloy Steel Yeeb Nkab yog qhov haum rau ASTM A234 WP0 series khawm wardings (WP9, WP9 (A182 F5, F9, F22, F91). Tag nrho cov ntaub ntawv no muaj cov tshuaj zoo sib xws thiab cov kws kho tshuab thiab tuaj yeem koom nrog lossis welded.
Chromium molybdenum pipes under ASTM and ASME specifications A\/SA 335 P1, P2, P11, P12, P15, P22, P91, P92, P122 are used in the power industry, while ASTM\/ASME A\/SA 335 P5, P9 are used in the petrochemical industry, It has strong crack resistance at high temperature and high siab, tuaj yeem siv rau hydrogen sulfide corrosion, hydrogen nres thiab embritting backingTensile lub zog (mpa)Cov phiaj yog annealed nyob rau ntau tus mob uas muaj lub zog. Vim tias cov phiaj hlau no yog ua haujlwm ntawm qhov kub thiab siab ib puag ncig yog li ntawd cov ntsiab lus tau suav nrog nws cov teeb meem ntau. Dab tsi ntxiv rau hauv kev tsim khoom ntxiv cov khoom sib txawv rau cov khoom sib txawv, qib siab ntawm chromium ntxiv zoo heev corrosion. Nws tseem muaj oxidation zoo tiv thaiv. Tiv taus oxygen tseem ceeb hauv petrochemical thiab roj kev lag luam thiab yog li cov phiaj no siv.
