Luv luv Ntawm Q390 Steel Phaj

 

Muaj ntau ntau hom steel phaj feem ntau siv hauv cov qauv steel, thiab Q390 steel phaj kuj yog ib qho ntawm lawv. Nws muaj cov khoom txias-forming zoo, vuam, thiab corrosion kuj.

 

Steel Qib Ntawm Steel Phaj

 

Raws li qib sib txawv thiab kev ua tau zoo, Q390 steel phaj tuaj yeem muab faib ua ntau qib xws li Q390B steel, Q390C steel, Q390D steel, Q390Esteel, thiab lwm yam.

 

Q390C, Q390D, Q390E qib steel phaj muaj qhov kub thiab txias toughness. Qhov no txhais tau hais tias cov hlau phaj tuaj yeem tswj tau lub zog siab thiab ductility nyob rau hauv cov huab cua txias, thiab tuaj yeem zam qhov tawg tawg los ntawm qhov kub thiab txias.

 

4 Cov yam ntxwv tseem ceeb ntawm Q390 Steel Phaj

01/

Q390 steel phaj muaj lub zog muaj zog thiab lub zog tensile, uas txhais tau tias cov hlau phaj tuaj yeem nqa hnyav hnyav.

02/

Q390 steel phaj muaj lub zog zoo heev, uas tuaj yeem nqus tau ntau lub zog thaum muaj kev ntxhov siab thiab txhim kho av qeeg tsis kam ntawm steel qauv vaj tse.

03/

Cov khoom siv vuam zoo heev tso cai rau Q390 steel phaj txuas los ntawm ntau txoj kev vuam.

04/

Kev ruaj ntseg thiab kev pab cuam lub neej ntawm cov qauv steel nyob ntawm lub zog thiab kav ntev ntawm cov hlau, thiab Q390 steel phaj qhia tau hais tias zoo tiv thaiv corrosion thiab oxidation nyob rau hauv ib puag ncig hnyav.
