Dab tsi yog cov xeeb ceem zoo ntawmA302 Qib B?
Muaj zog thiab muaj sia
Muab lub zog tensile (feem ntau 48-620 MPA / 70-90 Ksi) thiab tawm los ntawm 275 MPa / 40 KSI / 40 KSI / 40 KSI), ua rau nws haum rau kev kub-rau-siab siab.
Molybdenum (mo) hauv nws cov ntawv sau ua kom tsis kam ua rau kom muaj qhov kub thiab rog nyob rau hauv nruab nrab qhov chaw nruab nrab (piv txwv li txog 480℃/ 900℃f).
Zoo heev cuam tshuam
Cov khoom ua pov thawj zoo unch nyuaj thiab cuam tshuam tsis kam ntawm ambient thiab me ntsis v-nees kub (piv txwv li muaj kev pheej hmoo
Weldability thiab Formability
Feem ntau tau tshaj nrog cov txheej txheem vuam (piv txwv li, smaw, gtaw) thaum muab cov khoom siv tshav kub kom zoo thiab tom qab siv hluav taws xob.
Tswj hwm lub sijhawm thaum muaj kev ua haujlwm, tso cai rau kev khoov lossis dov mus rau hauv cov cylindrical lossis spherical duab yam tsis muaj kev ploj ntawm cov khoom siv mechanical.
Corrosion thiab Hydrogen Kuj
Molybdenum txhim kho kom tsis kam mus rau hydrogen-inducts cracking (hic) thiab sulfide kev ntxhov siab corrosion (SSC)
Muaj cov tshuaj oxidation zoo dua li cov hlau ua haujlwm ntawm cov hlau uas nce qib siab, txuas ntxiv lub neej pabcuam hauv cov kev siv hluav taws kub siab.
Tus nqi haum kev siv kub-kub siab
Cov Nyiaj Pov Tseg Alloy (MolanBdenum) los muab cov khoom siv kub kom zoo li cov roj hmab, ua kom sov, thiab cov roj kub hauv lub zog thiab roj / roj sector.
