1. Cov Khoom Txhais Lus thiab Cov Qauv Txheej Txheem
S3269 yog titanium {- DidiCized Austenitic Stainless Hlau (sib xws mus rau Suav tsim 07cr18ni. Nws cov cwj pwm tseem ceeb thiab cov qauv muaj xws li:
Composition Tsim:
Chromium -} Npib (Cr 17.0-12%) + NI 6.0%)) Feem ntau C%, feem ntau 0.30-0.60%);
Ultra - Cov pa roj av qis (C Tsawg dua li ntawm 0.08%), tswj xyuas phosphorus thiab sulfur (p tsawg dua lossis sib npaug lossis sib npaug 0.030%);
Cov Qauv Siv Ua Lag Luam: ASTM A312 / A358 (American txheem (GB / T 14976 (Suav tus qauv) {3} Cov tseem ceeb ntawm cov tseem ceeb
Intergranular corrosion: hla ittm A262 Xyaum E Kuaj (Nitric Acid + Fluoride Cheeb Tsam);
High - kub kev ua tau zoo:
Kev ua haujlwm tsis tu ncua kub 800 degree, luv - sij hawm tiv taus 900 degree;
Oxidation tsis kam mus rau 304 stainless hlau (oxidation hnyav nce ntawm 800℃yog txo los ntawm 30%);
Cov yam ntxwv ua:
ER321 Vuam hlau yog pom zoo rau vuam, xav tau tsis muaj preheating;
Kev kho kom daws (ua kom txias sai ntawm 1010-1120 degree) yog qhov yuav tsum tau tom qab ua haujlwm txias.
3. Cov ntaub ntawv raug:
Petrochemical Cov Khoom Siv:
Catalytic cracking chav tsev reactor piping;
High -} hydrogen piping;
Zog thiab FAIS:
Roj turbine khib nyiab cua sov sov boiler Superheater tubing;
Nuclear pelfel elecary ib qho nruab nrab (tsis {{0} }lear qib);
Cov kev tshwj xeeb:
Acidic media ntim cov yuav tsum tsis tas yuav tsum muaj tsis muaj qhov xav tau {{weld kev kho cua sov {}} sib piv nrog cov ntaub ntawv zoo sib piv
VS30400 (304 steel hlau):
Titanium {-} Dabrized tsim tseem txhim kho txhim kho intergranular tsis kam;
High - lub zog kub nce los ntawm 10% (800 degree);
thiab S34700 (347 stainless hlau):
Titanium cov carbon -} bind lub peev xwm yog me ntsis qis dua rau Niobium, tab sis tus nqi yog 5-8% qis dua.
5. Kev ua haujlwm thiab ua cov ntsiab lus tseem ceeb
Cov ntawv pov thawj tseem ceeb: Ib qho kev xeem titanium cov ntsiab lus (ti / c ntau dua los yog sib npaug rau 5).
Sau ntawv:
Kub txoj kev ua tiav dov lub rhaub ntau dua lossis sib npaug nrog 900 degree;
Tsis txhob sib xyaw nrog cov cuab yeej steel (los tiv thaiv cov hlau tsis huv).
