Tshuaj lom neeg muaj pes tsawg leeg ntawm JIS G3444 ERW YEEB thiab nws qhov tseem ceeb
1. Cov pa roj carbon (c):
Cov pa roj carbon yog lub ntsiab lus uas cuam tshuam lub zog thiab hardness ntawm cov hlau. Hauv JIS G3444 txheem, qib sib txawv ntawm cov kav hlau sib txawv muaj cov ntsiab lus ntawm cov pa roj carbon ntau thiab cov khoom siv weldability ntawm cov khoom.
2. Silicon (Si):
Silicon tsuas yog siv los ua deoxidizer hauv cov hlau, pab txhim kho lub zog thiab tawv ntawm cov hlau. Qhov kev txwv ntawm silicon cov ntsiab lus hauv cov qauv yuav pab tswj cov khoom siv me me ntawm cov khoom.
3.Manganese (MN):
Manganese yog qhov tseem ceeb rau kev txhim kho lub zog thiab hardness ntawm cov hlau, thaum tseem pab tau tshem tawm cov kev tsis zoo ntawm cov leej faj.
4. Phosphorus (p) thiab Sulphur (s):
Phosphorus thiab cov leej faj yog cov khoom muaj teeb meem hauv cov hlau, uas txo cov plasticity thiab tawv ntawm cov hlau.
Cov tshuaj lom neeg tshwj xeeb ntawm cov tshuaj lom neeg no ua kom muaj kev ua tau zoo thiab ntseeg tau ntawm JIS G3444 ERW YEEB NKAUS HAUV ntau cov ntawv thov. Los ntawm kev tswj cov ntsiab lus ntawm cov ntsiab lus no, nws muaj peev xwm ua kom ntseeg tau tias cov yeeb nkab steel ua tau raws li cov kev xav tau kev tsim tshwj xeeb thiab ib puag ncig.

1. Cov Khoom Zoo Tshaj:
- JIS G3444 ERW cov roj hlau steel yog cov zoo steel kav tsim nrog kev lag luam ntau yam suav nrog kev tsim kho nrog rau kev tsim kho, kev tsim kho vaj tse, tsuas thiab tsheb thauj mus los.
2. Durabe:
- Cov kav hlau hlau no yog ua los ntawm cov khoom siv steel steel, nrog hnav thiab corrosion kuj cov yam ntxwv, haum rau kev siv nyob rau hauv ib puag ncig ib puag ncig. Lub raj raj raj siv hluav taws xob kom txhawb nqa kom muaj lub zog ntxiv thiab cov kav ntev, cia nws ua kom muaj qhov siab ua haujlwm siab thiab kub.
3. Versatility:
- Cov kav dej ERW muaj ntau qhov ntau thiab tsawg rau cov khoom siv sib txawv, suav nrog kev kho cov dej, kev kho kom huv si thiab kho tshuaj lom neeg. Cov kav dej tseem tau yoog raws li ntau yam kev tsim khoom, suav nrog machining, vuam thiab khoov, ua rau lawv yooj yim siv nyob rau hauv cov xwm txheej sib txawv.
4. Kev tsim qauv tsim:
- Tsim tau siv cov kev tawm tsam vuam (ERW) txheej txheem, uas cuam tshuam nrog kev sib tw ntawm cov hlau hluav taws xob siv lub zog ua haujlwm siab. Cov txheej txheem no tau ua rau cov kav dej zoo nrog cov pob qij txha uas muaj zog uas muaj zog thiab ruaj khov dua li cov kav dej tso cai.
