Ntov ntawm cov hlau ntu

Qhov ntom ntawm cov steel ntu txawv nyob ntawm cov khoom thiab hom. Cov hauv qab no yog qhov dav dav ntawm cov khoom siv steel steel thiab cov ntaub ntawv muaj feem xyuam:

Cov pa roj carbon steel
Qhov ceev ntawm tib neeg cov hlau steel feem ntau yog 7.85 g / cm³, uas yog cov feem ntau siv siv tau tus nqi hauv kev tsim kho. Piv txwv li, cov khoom siv ntawm kub-rolled h-puab hlau feem ntau yog Q235b lossis Q345B lossis QUCTITY yog suav raws li 7.85.

 

Stainless hlau seem
Qhov ceev ntawm cov hlau stainless hlau yog txawv me ntsis:

Qhov ceev ntawm Austenitic 304 stainless hlau yog 7.93 g / cm³
Qhov ceev ntawm Martensitic 410 Stainless hlau yog 7.75 g / cm³
Qhov sib txawv no yuav tsum tau ua haujlwm tshwj xeeb hauv kev tsim qauv engineering, tshwj xeeb tshaj yog nyob rau hauv corrosion tiv thaiv thiab load-cov kabmob suav.

 

Txhuas Alloy Hlau Tshooj
Qhov ceev ntawm aluminium alloy steel stains yog qhov qis dua, feem ntau ntawm 2. {}}. 8 g / cm³. Piv txwv li, qhov ceev ntawm 6061- t6 aluminium alloy i-nqaj yog suav ua 2.7. Aluminium alloy hlau feem ntau siv nyob rau hauv cov qauv uas yuav tsum tau txo phaus vim nws cov cwj pwm me me.

 

Lwm Cov Hlau Tshwj Xeeb

Qhov ntom ntawm cov hlau ceev (muaj 9% tungsten) yog 8.3 g / cm³
Qhov ntom ntawm cov hlau ceev (muaj 18% tungsten) yog 8.7 g / cm³
Lub ntom ntom ntawm cov roj carbon hlau tsawg (muaj 0. 1% carbon) yog 7.85 g / cm³
Lub ntom ntom ntawm cov hlau roj carbon hlau (muaj 0. 4% carbon) yog 7.82 g / cm³
Qhov ntom ntawm cov pa roj carbon hlau siab (muaj 1% carbon) yog 7.81 g / cm³
Cov ceev sib txawv ntawm cov hlau no feem ntau yog vim muaj cov sib txawv sib txawv.

Kev ceev faj hauv kev siv cov ntawv thov

Qhov ceev ntawm cov hlau ntawm tib cov ntaub ntawv yuav hloov kho los ntawm ± 0. 5%, uas yog vim qhov sib txawv hauv cov txheej txheem smelting.
Thaum xam qhov hnyav ntawm cov hlau, nws yog ib qho tsim nyog los ua ke ntawm thaj chaw hla kev hla kev thiab qhov ua piv txwv, thiab kev pom zoo {1} {1} {1} Qhov siab yog tso cai rau qhov yuam kev ntawm ± 3%).
Ntsiab lus: Qhov ntom ntawm cov hlau yog qhov tseem ceeb ntsuas rau kev xaiv xaiv thiab kev xam hnyav, thiab nws yuav tsum muaj cov ntaub ntawv raug raws li cov ntaub ntawv tshwj xeeb thiab hom. Qhov ntom ntawm cov hlau siv tshuaj ntsuab yog 7.85 g / cm³, thaum lub ntom ntom ntawm stainless hlau thiab aluminium alloy hlau sib txawv raws li cov muaj pes tsawg leeg. Hauv kev siv cov kev siv, sib txawv me me hauv qhov ntom ntom yuav muaj kev cuam tshuam tseem ceeb ntawm tus qauv tsim qauv thiab tus nqi.
