Lavxias tus qauv 09G2S steel feem ntau yog siv los tsim cov ntawv hlau, cov kav dej steel thiab cov qauv hlau, xws li cov tsev, txuas hniav, Roj kav dej, tank, nkoj, thiab tsheb. Nws lub zog siab thiab zoo weldability ua rau nws tsim nyog rau cov qauv kev tsim vaj tsev bearing loj static, dynamic thiab vibration loads.
Qhov zoo:
1. Lub zog siab: 09G2S steel muaj lub zog tensile zoo thiab lub zog tawm los, haum rau cov haujlwm engineering nrog cov khoom siv siab zog. 2. Weldability: 09G2S steel muaj qhov zoo weldability, ua kom yooj yim rau vuam thiab kev sib txuas ua haujlwm. 3. Zoo plasticity thiab toughness: Cov hlau no muaj cov yas zoo thiab toughness, cia nws tiv taus qee qhov cuam tshuam sab nraud thiab deformations. 4. Corrosion tsis kam: 09G2S steel tuaj yeem txhim kho nws cov kev tiv thaiv corrosion los ntawm kev kho cua sov los yog txheej, ua rau nws tsim nyog rau ib puag ncig uas yuav tsum muaj kev tiv thaiv corrosion.
Qhov tsis zoo:
1. Tus nqi siab: Muab piv rau cov hlau tsis tshua muaj carbon tsawg, 09G2S steel muaj tus nqi siab dua, uas tuaj yeem ua rau cov nqi ntau lawm hauv cov ntawv thov loj. 2. Cov ntsiab lus siab ntawm cov hlau: Txawm hais tias cov ntsiab lus ntawm 09G2S steel yog qhov tsawg, nws tseem yog me ntsis siab dua li cov pa roj carbon tsawg, uas yuav txwv qee qhov tshwj xeeb siv.
Yam ntxwv:
1. Lub zog muaj zog: Nws muaj lub zog ua haujlwm siab thiab lub zog tensile, thiab tuaj yeem tiv taus cov khoom loj thiab kev ntxhov siab. 2. Zoo toughness: muaj zoo heev toughness thiab cuam tshuam toughness, muaj peev xwm ua kom ruaj khov kev ua tau zoo nyob rau hauv kev cuam tshuam los yog vibration loads. 3. Zoo corrosion kuj: Nws muaj corrosion kuj zoo thiab tuaj yeem siv rau hauv qhov chaw ntub thiab corrosive. 4. Kev ua haujlwm zoo: 09G2S steel yog ib qho yooj yim los txiav, vuam, thiab khoov txias, haum rau ntau yam txheej txheem. Feem ntau, tus qauv Lavxias teb sab 09G2S steel muaj lub zog siab, zoo weldability thiab toughness, thiab yog haum rau cov qauv tsim engineering xav tau lub zog siab thiab corrosion kuj.
