Dab tsi yog qhov txawv ntawm 310 thiab 310S stainless hlau raj?
Qhov sib txawv tseem ceeb ntawm 310 thiab 310S stainless hlau raj yog nyob rau hauv lawv cov ntsiab lus carbon: 310S yog cov pa roj carbon tsawg (nrog cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.08%) ntawm tus qauv 310 (uas muaj cov ntsiab lus siab tshaj plaws ntawm 0.25%). Cov yam ntxwv no tso cai rau 310S los ua kom pom qhov zoo tshaj qhov kev ua haujlwm vuam thiab kev tiv thaiv corrosion, thaum tus qauv 310 muaj kev tiv thaiv ntau dua hauv qhov kub thiab txias.
310 vs 310S Stainless hlau yeeb nkab
Dab tsi yog 310 stainless hlau yeeb nkab?
310 stainless hlau tubing yog qhov kub-kub chromium-nickel austenitic stainless hlau paub txog nws qhov tshwj xeeb kub tiv taus mus txog 2100 degrees F (1150 degrees), zoo heev oxidation kuj, thiab superior creep kuj. Feem ntau siv nyob rau hauv furnaces, boilers thiab tshav kub exchangers, 310/310S yeeb nkab yog zoo tagnrho rau ib puag ncig hnyav. Cov ntsiab lus lossis cov npe muaj feem cuam tshuam suav nrog UNS S31000 / S31008, AISI 310 thiab 1.4845.
Qib 310S Stainless hlau yeeb nkab yog dab tsi?
Qib 310S stainless hlau tubing yog high-alloy, low-carbon austenitic stainless hlau, tshwj xeeb tsim los muab tshwj xeeb kub tsis kam thiab lub zog zoo nyob rau hauv qhov kub thiab txias (txog 2100℃F lossis 1149 degree). Nws yog siv nyob rau hauv ntau yam furnaces, boilers, tshav kub exchangers thiab petrochemical ua khoom. Tsab ntawv "S" hauv nws lub npe qhia tias nws cov ntsiab lus carbon qis dua li tus qauv Qib 310; Cov yam ntxwv no ua rau txo qis qhov tsis muaj zog ntawm cov khoom thiab txhim kho nws cov weldability.

310 vs. 310S Stainless Hlau Yeeb Nkab: Vuam thiab Corrosion
Piv rau tus qauv 310 stainless hlau (uas muaj txog li 0.25% carbon), 310S stainless hlau feem ntau ua tau zoo dua hauv kev siv vuam thiab cov kav dej kub vim nws cov ntsiab lus qis dua (ntau tshaj 0.08%); Cov pa roj carbon tsawg tsawg no pab txo qis carbide nag lossis daus, yog li txhim kho kev tiv thaiv intergranular corrosion tom qab vuam txheej txheem. Hauv kev tsim cov ntawv thov, 310S feem ntau yog qhov kev xaiv zoo tshaj plaws vim nws muaj qhov zoo tshaj tom qab vuam corrosion kuj nyob rau hauv high-temperature thiab corrosive ib puag ncig.
310 vs 310S Stainless hlau kav: Kub Resistance
310S yog tsim tshwj xeeb rau kev siv tas mus li, mus sij hawm ntev hauv qhov kub thiab txias. Nws cov ntsiab lus qis carbon zoo tiv thaiv nag lossis daus ntawm carbides (sensitization) nyob rau hauv qhov kub ntawm 500 txog 800 degrees, yog li tsis txhob cuam tshuam intergranular corrosion. 310 (Standard carbon, C tsawg dua los yog sib npaug rau 0.25%): Nws muaj ntau dua txhua yam ua haujlwm ntawm qhov kub thiab txias; Txawm li cas los xij, nws cov ntsiab lus carbon siab ua rau nws muaj kev nkag siab zoo thaum raug kub ntawm 500 degrees thiab 800 degrees rau lub sijhawm ntev. Yog li ntawd, nws yog qhov tsim nyog rau kev ua haujlwm tsis sib xws lossis luv luv ntawm qhov kub thiab txias. Nws qhov kub siab tshaj plaws tau pom zoo rau kev pabcuam txuas ntxiv yog 1035 degrees (1900 degrees F).
310 vs. 310S Stainless hlau kav: Qhov twg xaiv?
Yog tias koj qhov project cuam tshuam nrog cov txheej txheem vuam, lossis yog tias cov kav dej yuav raug rau qhov kub thiab txias ib puag ncig - nyob rau hauv thaj tsam ntawm 450℃txog 850℃- rau lub sijhawm ntev, 310S yog qhov kev xaiv zoo tshaj plaws. Txawm li cas los xij, yog tias daim ntawv thov xav tau qhov siab tshaj plaws ntawm kev ua haujlwm siab nyob rau hauv qhov kub siab heev - thiab vuam tsis yog qhov tseem ceeb rau kev txiav txim siab -, ces 310 yuav yog ib qho kev xaiv los txiav txim siab.
