A516GR70 yog dab tsi?
A516GR70yog qib steel phaj rau cov hlab ntsha siab teev nyob rau hauv American ASTM tus qauv. Ntawm no, "A516" qhia tus lej tus qauv, thaum "GR70" sawv cev rau nws qib siab zog. Cov hlau no feem ntau yog siv los tsim cov khoom siv welded hauv nruab nrab - mus rau - qis - cov hlab ntsha kub. Nws pom zoo weldability thiab cuam tshuam toughness.
Tshuaj muaj pes tsawg leeg
- Carbon (C): Tsawg dua lossis sib npaug rau 0.30%
- Manganese (Mn): 0.79-1.30%
- Phosphorus (P): Tsawg dua lossis sib npaug rau 0.035%
- Sulfur (S): Tsawg dua lossis sib npaug rau 0.035%
- Silicon (Si): 0.13-0.45%
Yog li, A516GR70 yog cov khoom siv carbon steel, tsis yog stainless hlau.

Qhov tseem ceeb sib txawv ntawm carbon steel thiab stainless hlau
| Yam ntxwv | A516GR70 (Carbon Steel) | Stainless hlau (piv txwv li, 304/316) |
| Lub ntsiab lus | Fe-C-Mn-Si,trace Cr,Mo | Siab Cr (216%), Ni (28%) |
| Corrosion Protection Mechanism | Relies rau saum npoo txheej / inhibitors; optimized rau H2S ib puag ncig corrosion kuj | Cia siab rau cov yeeb yaj kiab passive rau tus kheej - tiv thaiv |
| Qib Siab | Nruab nrab -High Strength (Yield Strength 2260 MPa) | Feem ntau qis zog (Austenitic SS-200 MPa) |
| Nqi Factor | Kev lag luam txheeb ze (~ 1/3 rau 1/2 tus nqi ntawm stainless) | Nqis, nyob ntawm cov khoom siv nickel/chromium |
| Ib puag ncig tsim nyog | Nruab nrab / qis kub, tshwj xeeb corrosive tej yam kev mob (xws li, H2S) | Muaj zog oxidizing acids, kub kub, los yog huv si corrosive ib puag ncig |
Qhov sib txawv tseem ceeb ntawm carbon steel thiab stainless hlau
Kev sib xyaw ua ke
Stainless hlau muaj tsawg kawg yog 10.5% chromium thiab feem ntau suav nrog lwm cov hlau alloy xws li npib tsib xee. Cov pa roj carbon steel feem ntau yog tsim los ntawm cov hlau thiab cov pa roj carbon, nrog cov qib qis ntawm cov ntsiab lus alloy.
Kev ua tau zoo sib txawv
Stainless hlau muaj superior corrosion kuj, thaum carbon steel yog nquag rusting nyob rau hauv ib puag ncig ntub. Stainless hlau feem ntau muaj qis zog thiab hardness dua carbon steel tab sis pom zoo toughness thiab ductility.
Daim ntawv thov Scenario
Stainless hlau yog tsim rau ib puag ncig uas xav tau kev tiv thaiv corrosion, xws li kev ua zaub mov thiab khoom siv kho mob. Cov pa roj carbon steel yog siv dav hauv cov khoom siv hauv cov khoom siv, cov hlab ntsha siab, thiab lwm yam kev siv uas yuav tsum muaj lub zog siab thiab kev tiv thaiv xeb tuaj yeem ua tiav los ntawm kev pleev xim lossis lwm txoj hauv kev.
