1. Cov ntsiab lus txhais thiab cov yam ntxwv sib xyaw
10CR18NI9NBCU3bn yog qhov siab -} Cov hlau tsis tshua muaj cua sov} Nws cov tshuaj tsim tsim nta:
High chromium-} Npib Tsib Cickel Puag (Cr 17.0-19.0 .0%): Ua kom cov kab xeb tsis kam;
Ntau yam ntxiv dag zog:
NB: 0.30-0.60% (carbide stabilization);
CU: 2.80-3.50% (txhim kho kev ntxhov siab corrosion tsis kam);
B: 0.001-0-0.005% + n: 0.10-0.20% (synergistic nplej muaj zog zuj zus);
Tsawg cov pa roj carbon tswj (c tsawg dua los yog sib npaug rau 0.10%): Zam kev zam kev txaus ntshai.
Cov Qauv Txheej Txheem: feem ntau ua raws li Astm A312 / A358 lossis lub hwj huam nuclear {}}} m.
2. Cov ntsiab lus kev ua tau zoo
Kuj mus rau qhov chaw muaj ib puag ncig zoo:
Tiv taus siab - kub, siab}} qhov dej siab corrosion (300℃/ 8mpa dej txias, xeb tus nqi<0.01mm/year);
Kev ntxhov siab corrosion cracking (SCC) tiv thaiv peb zaug zoo dua 316L steel;
Cov Khoom Siv Neeg Kho Tshuab:
Chav sov lub zog loj dua los yog sib luag rau 620mpa, siab- kub lub zog ntau dua los yog sib npaug ntawm 600mpa ntawm 650 degree;
Elongation ntau dua los yog sib npaug rau 35%, cuam tshuam rau lub zog loj dua los yog sib luag rau 60j ntawm -196 degree;
Cov yam ntxwv ua:
Vuam yuav tsum muaj roj av tiv thaiv (tig vuam yog qhov zoo tshaj plaws);
Solub kho qhov kub thiab txias 1100-1150 degree.
3. Cov ntawv thov raug
Cov Khoom Siv Hluav Taws Xob Nuclear:
Cov tshuaj tua dej ua kom muaj reactor thawj Circuita uxiliae piping;
Chav hluav taws xob txhawb kev txhawb nqa;
Offshore engineering:
High -} siab piping rau tob-} ntug hiav txwv drilling platform;
Kev sib txuas ntawm tshav kub ua rau dej hiav txwv Desalination Nroj Tsuag;
Cov Kev Xav Tau Tshwj Xeeb:
High - theem qib radoadactive chaw khaws cia cov khoom ntim;
Supercritical Piping rau geothermal fais fab nroj tsuag . 4. sib piv nrog cov ntaub ntawv zoo sib piv
vs . 316 ln:
Tooj + Niobium Composite Qhov Cuab Zog ua lub zog ua rau muaj zog los ntawm 25%;
Boron thiab Nitrogen Synergistically txhim kho cov qoob loo nplej ua kom tsis taus hluav taws xob puas tsuaj;
vs . 904 l:
Qis dua npib tsib xee cov ntsiab lus, 40% tus nqi qis;
Piv piv rau corrosion tsis kam nyob rau hauv chloride -}} muaj ib puag ncig.
5. Kev Pab Cuam thiab Tswjhwm Tswjhwm Zoo
Daim Ntawv Pov Thawj Tseem Ceeb:
Irradiation ntsuam xyuas kev ntsuam xyuas (ceev no cov neuchon flux ntau dua lossis sib npaug 1 × 10²¹n / cm²) yuav tsum tau;
Intergranular kev sim siab (ib iterm A262 Xyaum E);
Yuav tsum tau xeem:
100% eddy tam sim no thiab ultrasonic ua ke sim;
Ferrite cov ntsiab lus kev sim (tsawg dua los yog sib npaug rau 5%);
