16Mo3 yog European molybdenum-alloyed steel (EN 10028-2) nrog ntxiv Molybdenum kom zoo dua siab-kub lub zog thiab corrosion kuj, thaum A516 Qib 70 yog ib qho American carbon-manganese steel (ASTM A516) rau kev muab lub zog zoo dua li cov hlab ntsha, tab sis tsis tshua muaj zog. Qhov sib txawv tseem ceeb yog 16Mo3 cov ntsiab lus molybdenum, ua rau nws zoo dua rau qhov kub siab, qhov A516 Gr 70 yog qhov muaj zog, kev xaiv dav dav rau cov xwm txheej nruab nrab, feem ntau siv hauv boilers thiab cov hlab ntsha siab.

Qhov txawv tseem ceeb
Cov ntsiab lus ntawm Alloy: 16Mo3 muaj Molybdenum (0.25-0.35%), uas txhim kho kev ua haujlwm siab -kub thiab corrosion resistance, whereas A516 Gr 70 feem ntau yog carbon-manganese uas tsis muaj cov ntsiab lus Mo.
Cov qauv: 16Mo3 ua raws li European EN 10028-2 cov qauv, thaum A516 Gr 70 ua raws li American ASTM A516 cov qauv.
Daim Ntawv Thov Kub: 16Mo3 yog qhov zoo dua rau qhov kub siab dua (txog 600 degree) vim nws cov ntsiab lus molybdenum, thaum A516 Gr 70 yog rau kev pabcuam kub qis rau nruab nrab.
Mechanical Properties: A516 Gr 70 muaj zog zoo (Tensile: 485-620 MPa) thiab toughness, tab sis 16Mo3's alloy muab superior tshav kub.
Thaum twg siv qhov twg
Xaiv 16Mo3 rau cov ntawv thov uas yuav tsum tau ua kom muaj cua sov zoo dua, xws li nyob rau hauv siab - kub boilers lossis cov hlab ntsha raug rau qhov chaw muaj corrosive.
Xaiv A516 Qib 70 rau kev siv dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav dav hlau dav hlau dav hlau dav hlau dav hlau dav hlau dav hlau dav hlau siv hauv nkoj dav hlau siv lub nkoj siab siab uas muaj qhov ntsuas kub nruab nrab thiab lub zog zoo / toughness yuav tsum muaj, feem ntau hauv cov roj, roj, thiab kev lag luam petrochemical.
