Dab tsi yog cov yam ntxwv tshwj xeeb ntawm cov hlau alloy puag ncig?
Alloy round steel feem ntau nthuav tawm ntau yam khoom tseem ceeb, suav nrog:
Lub zog:
Tensile zog: Nws sawv cev rau qhov siab tshaj plaws kev ntxhov siab uas cov alloy puag ncig steel tuaj yeem tiv taus ua ntej tawg thaum rub hauv nro. Lub zog tensile siab ua kom cov khoom tuaj yeem tuav cov khoom tseem ceeb yam tsis muaj kev ua haujlwm.
Yield zog: Qhov no yog qhov kev ntxhov siab uas cov khoom pib deform plastically. Lub zog tawm los ntau dua qhia tias muaj kev tiv thaiv ntau dua rau kev deformation mus tas li.
Hardness: Ntsuas cov khoom tsis kam rau indentation lossis khawb. Hard alloy round steel yog tsim rau cov ntawv thov uas hnav tsis kam yog qhov tseem ceeb, xws li hauv cov khoom siv uas muaj kev sib txhuam.
Ductility:
Elongation: Nws qhia txog lub peev xwm ntawm cov khoom yuav tsum tau ncab ua ntej fracturing. Zoo ductility tso cai rau cov hlau tsim thiab zoo li tsis muaj cracking.https://www.jstisco.com/
