1. Cov lus txhais thiab muaj pes tsawg leeg
S31059 yog qhov siab -}}}}}}}}}}}}}}}}}} awning rau European teeb tsa 1.4835). Nws cov qauv tsim muaj xws li:
High chromium-} Npib Tsib Cickel Puag (CR 24.0-22%, ni 19.0%) muab oxidation oxidation tiv taus;
Ultra -} Cov pa roj carbon qis thiab muaj ntau dua lossis muaj sib npaug lossis sib npaug lossis sib npaug lossis sib npaug ntawm cov kev pheej hmoo ntawm qhov tsis txaus ntseeg;
Nitrogen Fortification (N: 0.15 - 0.25%) Txhim Kho Lub Zog Kub Siab.
Cov Qauv Raws Li Txheej Txheem: EN 10216-5 (European Txuj Ci), ASTM A312 (American Txheem Xaiv) {2} Kev ua tau zoo thiab txwv tsis pub
Txwv ntsuas kub:
Nruam kev siv kub 1200℃(luv - Term 1300 degree);
Oxidation hnyav nce ntawm 1150 degree<0.5 mg/cm² (100 hours);
Cov Khoom Siv Neeg Kho Tshuab:
Chav chav kub tensile lub zog ntau dua los yog sib npaug rau 600 mpa, 800℃lub zog loj dua los yog sib npaug rau 150 MPA;
-} 196℃cuam tshuam lub zog loj dua los yog sib npaug rau 80 j (peev xwm rau cov ntawv thov tsawg-).
3. Cov ntaub ntawv raug
High - kub muaj qhov cub:
Cov kab txuas rau cov billet cua sov cua sov, cua sov -} tiv thaiv cov menyuam - Lub tshuab cua sov}} Lub tshuab cua tshuab hluav taws xob;
Iav melting rauv burner tsho;
Zog:
Molten ntsev reactor lub circuit Coalcuit;
Supercritical Coos Brayton Chargle Thaum Tshav Kub Kub Pa tshais.
4. Piv nrog cov khoom zoo sib xws:
Vs. S31008 (310s):
Nitrogen ntxiv ntxiv yuav nce siab siab - kub lub zog los ntawm 30%;
Ultra - Cov qauv siv carbon qis txhim kho post - weld corrosion;
Vs. RA253MA:
Tsis muaj tsawg lub ntiaj teb ntxiv, 25% txo nqi;
Piv sib piv thermal nkees kuj {{}}} kev yuav khoom thiab ua cov ntsiab lus tseem ceeb
Cov Kev Ntsuam Xyuas Tseem Ceeb:
Cov ntsiab lus ferrite tsawg dua los yog sib npaug rau 0.5% (kom tiv thaiv kev sigma theem embrittlement);
1200℃/ 100-teev oxidation ntsuas;
Ua Lus Ceeb Toom:
Cov kev sib sau kub yuav tsum muaj kev tiv thaiv Argon (los tiv thaiv kom tsis txhob decarburization);
Vuam yuav tsum siv er310 vuam hlau nrog 100% ntiv nplhaib roj thaiv.
