1. Cov coj zoo heev. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm lub alloy hnav-resistant txheej muaj 4 txog 5% carbon thiab 25 txog 30% chromium. Cov ntim ntim ntawm CR7C3 carbide hauv nws daim hlau hlau tau nce ntau dua 50%, thiab lub hardness yog hrc {}, lub hardness yog hv 1400-1800. Txij li thaum carbides tau muab faib rau kab ntsug hauv cov kev coj ntawm kev hnav, txawm muab piv nrog cov khoom siv sib xyaw thiab tawv tawv, cov coj tsis kam ntau dua ob npaug. Qhov kev sib piv ntawm cov kev sib piv tiv taus nrog ntau cov ntaub ntawv yog raws li hauv qab no: (1) nrog cov tshuaj ntsuab qis; 20 ~ 25: 1 (2 (2) Nrog rau-cam cov roj tseem ceeb cam khwb cia hlau; 1.5 ~ 2.5: 1
2. Lub substrate ntawm cov hnav-res resistant composite steel phaj nrog cov kev cuam tshuam zoo tsis tshua muaj carbon lossis tsawg alloy. Cov ntaub ntawv tawv xws li cov hlau stainless cuam tshuam txog qhov zoo ntawm bimetals. Cov txheej hnav-resistant tiv thaiv cov hnav ntawm kev abrasive nruab nrab, thiab lub hauv paus phaj bears lub load ntawm nruab nrab, yog li nws muaj kev cuam tshuam zoo. Nws tuaj yeem tiv thaiv qhov cuam tshuam thiab hnav cov high-tso hoppers hauv cov khoom conveying tshuab.
3. Lub alloy hnav-resistant txheej nrog zoo dua kub tsis kam yog siv nyob rau hauv kev ua haujlwm tsawg dua lossis sib npaug rau 600 degree. Yog tias Vanadium, Molybdenum thiab lwm yam alloys tau ntxiv rau lub alloy hnav-resistant txheej, nws tuaj yeem tiv taus qhov kub kub tsawg dua lossis sib npaug nrog 800 degree. Cov kev ua haujlwm kub tau pom zoo yog raws li hauv qab no: Cov pa roj carbon steels zoo li yog pom zoo rau kev siv ntawm qhov kub tshaj 380 degree; Tsawg-alloy tshav kub-resist hlau cov hlau daim hlau (15crmo, 12cr1mov, thiab lwm yam) tau pom zoo rau kev siv ntawm qhov kub tshaj 540 degree; Thaum tshav kub kub tiv thaiv stainless hlau substrates yog pom zoo rau qhov kub tsis muaj siab dua 540 degree. Siv nyob rau hauv 800 degree ua hauj lwm mob.
4. Zoo corrosion tsis kam ntawm alloy txheej ntawm cov ris-resistant Nws tuaj yeem siv rau hauv qee zaus xws li thee poob log thiab cov kev lom zem los tiv thaiv cov nplaim tawg.
