A333Gr3 cryogenic yeeb nkab yog ib hom yeeb nkab steel siv nyob rau hauv qis - qhov kub thiab txias ib puag ncig, feem ntau yog rau cov kav dej xa hluav taws xob thauj khoom cryogenic. Cov hlau siv nyob rau hauv A333Gr3 cryogenic yeeb nkab muaj qee yam qis -kub tsis kam thiab tuaj yeem siv rau hauv ib puag ncig hauv qab -45℃.
A333Gr3 cryogenic yeeb nkab yog ua los ntawm A333Gr3 steel. Lub ntsiab Cheebtsam ntawm A333Gr3 steel yog carbon, silicon, manganese, sulfur, thiab phosphorus, nrog ib tug tsawg carbon cov ntsiab lus thiab siab purity, uas ua rau zoo heev tsis tshua muaj - kub kuj.
● Cov Khoom Tseem Ceeb (%):
Cov pa roj carbon (C) 0.12
Silicon (Si) 0.25
Manganese (Mn) 0.48
Nickel (Ni) 3.78
Phosphorus (P) 0.011
Sulfur (S) 0.004
● Mechanical Properties:
Tensile Strength (σb): Ntau dua lossis sib npaug li 450MPa
Yield Strength (δs): Ntau dua lossis sib npaug rau 240MPa
Elongation (δ5): Ntau dua lossis sib npaug li 20%
● Cov yam ntxwv thiab kev siv:
A333Gr3 steel yog ib qho zoo - steel hlau nrog ferrite matrix. Lub finer lub grain loj, qhov zoo dua lub toughness. Cov nominal muaj pes tsawg leeg ntawm cov hlau no yog 3.5% Ni, abbreviated li 3.5Ni steel. Ni ho txhim kho lub toughness ntawm lub matrix. Nws muaj qee qhov Mn thiab Si, thiab muaj qhov sib piv Mn/C siab (Mn/C=4), uas yog qhov zoo rau kev txhim kho toughness. Nrog rau qhov tsis tshua muaj zog tawm los thiab qis qis ntawm leej faj (S) thiab phosphorus (P) impurities, hom hlau no pom zoo qis- qhov kub thiab txias ua haujlwm, txo nws qhov cuam tshuam rau nkig tawg.
Vim nws qhov kev ua tau zoo qis- qhov kub thiab txias, A333Gr3 steel kav tau dav siv hauv nruab nrab- thiab qis- cov txheej txheem cryogenic cov kav dej hauv cov nroj tsuag ethylene ua haujlwm ntawm -46 txog -100℃.
