Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4713 / X10CrAlSi13

Zoo heev High -Temperature Oxidation Resistance:Cov ntsiab lus ntawm txhuas (0.70-1.20%) txhawb kev tsim kom ruaj khov aluminium oxide nplai uas muab kev tiv thaiv zoo tshaj plaws rau kev ntsuas thiab oxidation txog li 900℃(1650℃F).

Zoo Thermal Fatigue Resistance:Cov qauv ferritic muab kev ua haujlwm zoo rau thermal cycling, ua rau nws tsim nyog rau kev siv nrog rov ua cua sov thiab txias.

Tus nqi qis:Tsis muaj cov nickel thiab cov ntsiab lus tsis tshua muaj alloy ua rau nws muaj txiaj ntsig zoo dua li austenitic cua sov- qib resistant.

Sib nqus thiab Weldable nrog Kev Kho:Muaj zog sib nqus thiab tuaj yeem welded nrog cov txheej txheem tsim nyog, txawm tias preheating yuav tsum tau.

 

Cov ntawv thov tseem ceeb:

Rauv Cheebtsam:Cov khoom siv cua sov, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov phiaj xwm txhawb nqa.

Cov khoom siv kho cua sov:Retorts, muffles, thiab pob tawb rau kev kho cua sov.

Automotive Exhaust:Catalytic converter txhawb nqa, tso tawm manifolds, thiab tiv thaiv tshav kub.

Cov khoom siv hauv tsev:Burner Cheebtsam nyob rau hauv lub qhov cub gas, qhov cub rhaub, thiab qhov cub qhov cub.

Muaj cua sov:Radiant tubes thiab cua sov cov ntsiab lus sheaths.

Petrochemical:Cheebtsam hauv nruab nrab- cov khoom siv txheej txheem kub.

 

1.4713 piv rau 1.4762 (446) thiab 1.4742 (X10CrAlSi18) li cas?
1.4713 muaj cov ntsiab lus chromium qis (12-14%) piv rau 1.4762 (446) uas muaj 23-27% Cr, thiab 1.4742 (X10CrAlSi18) uas muaj 17-19% Cr. Qhov no ua rau qis tshaj qhov kev pabcuam kub: 1.4713 yog qhov tsim nyog mus txog ~ 900 degree, thaum 1.4762 tuaj yeem siv mus txog ~ 1100 degree. Cov ntsiab lus ntawm txhuas muab kev tiv thaiv oxidation ntxiv thoob plaws peb qib . 1.4713 yog kev lag luam ntau dua vim yog cov ntsiab lus chromium qis thiab feem ntau xaiv rau cov ntawv thov uas xav tau qhov kub thiab txias (txog 900℃). Rau cov ntawv thov kub dua (siab dua 900 degree), 1.4762 lossis 1.4742 nrog cov ntsiab lus chromium siab dua raug pom zoo.

 

Dab tsi yog qhov kev txiav txim siab vuam rau 1.4713?
Vuam 1.4713 yuav tsum tau saib xyuas vim nws cov qauv ferritic thiab cov ntsiab lus txhuas. Cov ntsiab lus tseem ceeb suav nrog:

Kev siv hluav taws xob qis qis yog qhov tseem ceeb los txo qis kev loj hlob ntawm cov qoob loo hauv tshav kub- cuam tshuam cheeb tsam

Preheating (200-300 degree) yog pom zoo rau cov seem tuab

Austenitic muab tub lim hlau (309L, 310L) raug pom zoo kom zoo dua vuam ductility

Tshaj tawm -weld annealing ntawm 750-800℃tej zaum yuav xav tau los kho cov ductility rau cov ntawv thov tseem ceeb
