ASTM A536 Nodular Cast Iron Bar | Spheroidal Graphite Iron Rod
Kev Taw Qhia Txog Khoom
ASTM A536 Nodular Cast Iron Bar yog cov khoom siv precision-engineered tsim rau kev siv ua haujlwm siab hauv hydraulic thiab automotive systems. Ua raws li tus qauv ASTM A536 nruj, cov hlau graphite spheroidal (SG) no ua ke lub zog ntawm hlau nrog cov yam ntxwv zoo dua ntawm castability thiab vibration-dampening ntawm hlau. Nws yog qhov tshwj xeeb tshaj yog rau nws qhov kev tiv thaiv kev qaug zog zoo heev, kev siv tshuab, thiab kev ruaj khov ntawm qhov ntev hauv qab siab.
Cov hlau nodular cast iron, tseem hu ua ductile iron, txawv ntawm cov hlau grey uas cov pa roj carbon ua cov spheroidal graphite nodules es tsis yog flakes. Qhov kev sib txawv ntawm cov qauv no ua rau nws muaj zog tensile thiab yield ntau dua, ua rau nws yog cov khoom siv txhim khu kev qha rau cov khoom thauj thiab cov chaw muaj kev ntxhov siab.
- cov hlau ductile yog tsim tawm raws li cov qauv thoob ntiaj teb. Cov qib hlau uas siv ntau ntawm cov hlau ductile yog qhia tawm ntau txoj hauv kev raws li ntau lub tebchaws thiab cov qauv.
Cov hauv qab no yog cov qib hlau ductile uas siv ntau tshaj plaws (qib) raws li ntau lub tshuab txheem:
