Kev sib piv ntawm Astm A387 qib 11 thiab qib 22
Composition:
- Qeb 11:Muaj kwv yees li ntawm 1% chromium thiab 0.5% molybdenum.
- Qib 22:Muaj txog 2.25% molybdenum thiab 1% chromium. Qhov no siab dua Molybdenum cov ntsiab lus tau txhim kho nws lub zog thiab kev tawm tsam rau qhov kub siab.
Cov Khoom Siv Neeg Kho Tshuab:
- Qeb 11:
Yam tsawg kawg nkaus paib zog: 205 MPa (30,000 PSI)
Yam Tsawg Kawg Tensile Lub Zog: 415 MPa (60,000 psi)
- Qib 22:
Yam tsawg kawg nkaus paib zog: 240 MPA (35,000 PSI)
Yam tsawg kawg nkaus tensile lub zog: 550 mpa (80,000 psi)
Cov Ntawv Thov:
- Qeb 11:Feem ntau siv hauv cov ntawv thov uas xav tau lub zog nruab nrab ntawm cov ntsuas kub, xws li hauv cov dej boilers thiab siab.
- Qib 22:Feem ntau siv hauv cov ntawv thov ntau dua uas muaj zog dua thiab tawm tsam nkag tau xav tau, suav nrog cov tshuab siv tshuaj lom neeg thiab tshuaj lom neeg.
Ntsiab lus:
Lub ntsiab sib txawv ntawm Astm A387 qib 11 thiab qib 22 thiab qib 22 thiab qib 15 thiab cov khoom siv neeg kho mob, thiab cov ntawv thov. Qib 22 feem ntau muaj kev ua tau zoo nyob rau hauv cov kev ua kub thiab kev ntxhov siab vim nws cov ntsiab lus molybdenum ntau dua, ua rau cov ntawv thov tseem ceeb tshaj plaws piv rau qib 11.
