Hnav Resistance Steel Phaj

Hnav-cov phaj hlau tiv taus yog cov khoom siv phaj tshwj xeeb tsim tshwj xeeb rau kev siv nyob rau hauv cov xwm txheej loj ntawm - cheeb tsam hnav thiab tsim kua muag. Feem ntau siv hnav- cov phaj steel resistant yog nyob rau hauv toughness, zoo plasticity ntawm zoo tib yam uas tsis muaj carbon steel los yog tsis tshua muaj hlau alloy steel nto los ntawm cov surfacing txoj kev ntawm ib tug tej thickness ntawm siab hardness, zoo heev hnav tsis kam alloy hnav- resistant txheej thiab ua los ntawm cov khoom phaj. Tsis tas li ntawd, muaj cam khwb cia hnav-cov phaj hlau tiv taus thiab alloy quenching hnav- cov phaj hlau resistant.

Hnav-resistant steel phaj muaj tsawg carbon steel phaj thiab alloy hnav- resistant txheej ntawm ob qhov chaw, alloy hnav- resistant txheej feem ntau yog 1/3 ~ 1/2 ntawm tag nrho cov tuab. ua hauj lwm los ntawm matrix los muab kev tiv thaiv rau sab nraud quab yuam xws li lub zog, toughness thiab plasticity thiab lwm yam kev ua tau zoo, los ntawm alloy hnav- txheej tiv thaiv kom tau raws li cov kev xav tau ntawm cov xwm txheej ntawm hnav- tiv taus cov khoom.

1, Zoo heev hnav tsis kam alloy hnav- resistant txheej ntawm cov tshuaj muaj pes tsawg leeg ntawm cov pa roj carbon ntsiab lus ntawm 4 ~ 5%, cov ntsiab lus chromium txog li 25 ~ 30%, lub koom haum metallographic ntawm Cr7C3 carbide ntim feem ntawm ntau tshaj 50%, macro-hardness ntawm HRC56 ~ 62vium carbide hardness Xyoo 1800, vim yog cov carbide rau hauv ib qho perpendicular rau kev coj thiab kev faib tawm, txawm tias tib qho kev sib xyaw thiab hardness ntawm casting alloy sib piv. Kev sib piv alloy, hnav tsis kam ua haujlwm tau nce ntau dua ob npaug.

2, Muaj kev cuam tshuam zoo hnav- tiv taus cov hlau phaj substrate rau cov pa roj carbon tsawg lossis cov hlau tsis muaj hlau. Stainless hlau thiab lwm yam ntaub ntawv toughness, xav txog qhov superiority ntawm bimetallic, hnav- txheej tiv thaiv los tiv thaiv kev puas tsuaj ntawm cov khoom siv xov xwm, lub substrate tiv thaiv lub load ntawm cov xov xwm, yog li muaj kev cuam tshuam zoo. Nws tuaj yeem tiv taus qhov cuam tshuam thiab kev puas tsuaj hauv cov khoom siv los tiv thaiv kev poob siab thiab lwm yam cuam tshuam thiab puas.

3, Zoo dua tshav kub tiv thaiv alloy hnav-cov txheej tiv thaiv tau pom zoo siv tsawg dua lossis sib npaug li 600℃kev ua haujlwm, yog tias cov hlau hnav- cov txheej txheem tiv thaiv hauv qhov sib ntxiv ntawm vanadium, molybdenum thiab lwm yam alloys, tuaj yeem tiv taus kub hnav tsawg dua lossis sib npaug li 800℃. Pom zoo kub yog raws li nram no: zoo tib yam carbon steel puag phaj yog pom zoo kom siv nyob rau hauv tej yam kev mob tsis siab tshaj 380 degree; qis- alloy tshav kub-resistant steel phaj (15CrMo, 12Cr1MOV, thiab lwm yam) puag phaj yog pom zoo kom siv nyob rau hauv tej yam kev mob tsis siab tshaj 540 degree; Thaum tshav kub kub-resistant stainless hlau puag phaj yog pom zoo kom siv nyob rau hauv tej yam kev mob tsis siab tshaj 800℃.

4, Zoo corrosion kuj hnav-resistant composite steel phaj alloy txheej muaj ib tug siab feem pua ​​ntawm cov hlau chromium, yog li nws muaj ib tug tej yam anti- xeb thiab corrosion kuj. Nws tuaj yeem siv rau qee lub sijhawm xws li thee poob lub tog raj kheej thiab funnel kom tiv thaiv cov thee sticking.

Peb muaj cov khoom muag txaus thiab tuaj yeem ntim thiab xa tuaj rau lub sijhawm luv tshaj plaws. Yog tias koj muaj kev xav tau ntawm kev puas tsuaj resistant steel phaj lossis lwm yam khoom kub dov steel phaj, thov hu rau kuv.
