Daim ntawv thov Scope:
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 tau 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.
Kev sib piv
Cov hauv qab no yog qee cov hlau zoo ib yam li 09G2S, uas tej zaum yuav muaj qee qhov zoo sib xws nrog 09G2S hauv kev ua haujlwm thiab siv:
q235 ib: Q235B yog cov khoom siv carbon steel nyob rau hauv Suav tus qauv GB / T 700-2006, uas muaj weldability zoo, processability thiab toughness.Nws yog dav siv nyob rau hauv kev tsim kho, txuas hniav, tshuab tsim thiab lwm yam kev lag luam, thiab muaj qhov zoo sib xws nrog 09G2S hauv qee yam ntawm kev ua haujlwm.
ASTM A36: ASTM A36 yog cov khoom siv carbon steel hauv Asmeskas tus qauv, uas muaj qee yam zoo sib xws nrog Q235B hauv kev ua haujlwm.Nws yog feem ntau siv hauv kev tsim khoom hauv kev tsim kho, kev tsim khoom thiab lwm yam kev lag luam.
S235 JR: S235JR yog cov khoom siv carbon steel hauv European tus qauv EN 10025-2, uas zoo ib yam li Q235B thiab ASTM A36 hauv kev ua haujlwm.Nws yog feem ntau siv hauv kev tsim kho, tshuab tsim thiab lwm yam haujlwm.
A572 Qib 50: Qhov no yog lub zog muaj zog qis-alloy structural steel hauv Asmeskas tus qauv, uas muaj qhov zoo weldability thiab corrosion kuj.Nws yog dav siv nyob rau hauv cov choj, kev tsim kho thiab kev tsim cov tshuab hnyav.
S355JR: S355JR yog cov hlau tsis tshua muaj hlau uas muaj zog hauv cov qauv European EN 10025-2, uas yog tsim rau kev tsim kho, tshuab thiab kav dej.
Nco ntsoov tias thaum cov hlau no qhia qee qhov zoo sib xws nrog 09G2S ntawm cov khoom thiab kev siv, tej zaum yuav muaj qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab cov khoom ua haujlwm.Thaum xaiv cov hlau tsim nyog, nws raug nquahu kom ua raws li koj qhov kev xaiv ntawm cov kev cai tshwj xeeb engineering, cov qauv kev qhia tshwj xeeb thiab cov chaw tsim khoom cov lus pom zoo.
