Yam khoom yog 1Cr18Ni9Ti
1Cr18Ni9Ti yog Suav tus qauv tsim rau austenitic stainless hlau, qhov tseem ceeb sib npaug rau UNS S32100 thiab ASTM 321 stainless hlau. Nws cov yam ntxwv tseem ceeb yog qhov sib ntxiv ntawm titanium, feem ntau yog tsawg kawg ntawm 5 npaug ntawm cov ntsiab lus carbon thiab txog li 0.70 feem pua, uas ua rau cov hlau ruaj khov tiv thaiv chromium carbide nag lossis daus thaum vuam thiab raug kub ntawm 450 txog 800 degrees C. Qhov no tiv thaiv rhiab heev thiab corrosion tom qab intergranular. Cov muaj pes tsawg leeg txhais tau hais txog 18 feem pua chromium, 9 feem pua nickel, thiab stabilizing titanium.
Dab tsi yog A312 Steel
ASTM A312 tsis yog qib steel tshwj xeeb; Nws yog tus qauv specification hu ua Standard Specification rau Seamless, Welded, thiab hnyav hnyav ua hauj lwm Austenitic Stainless hlau kav. Nws txhais cov kev xav tau rau kev tsim khoom, suav nrog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev, qhov siab ntev, kev ntsuas hydrostatic, thiab tsis yog- kev tshuaj xyuas kev puas tsuaj, rau cov kav dej austenitic stainless hlau npaj rau siab - kub thiab kev pabcuam corrosive. Cov qib uas tau teev tseg hauv qab A312 suav nrog TP304/304L, TP316/316L, TP321/321H, TP347/347H, thiab duplex qib xws li S31803/S32205.
Yuav txheeb xyuas cov yeeb nkab steel li cas
Kev txheeb xyuas cov yeeb nkab steel sib xyaw ua ke ntau txoj hauv kev: pom cov cim xws li stenciling nrog cov qauv, qib, qhov loj me, cov chaw tsim khoom, thiab cov xov tooj cua sov; cov ntaub ntawv soj ntsuam cov ntaub ntawv tracing tus xov tooj cua sov kom paub tseeb muaj pes tsawg leeg thiab cov khoom; Kev ntsuam xyuas sib nqus, txij li austenitic stainless hlau feem ntau tsis yog- sib nqus lossis tsuas yog sib nqus me ntsis thaum carbon, ferritic, thiab martensitic steels yog cov hlau nplaum sib nqus; txim taws kuaj los ntawm tus kws tshaj lij; tshuaj xyuas qhov chaw rau cov ntsiab lus tseem ceeb; Kev txheeb xyuas cov ntaub ntawv zoo nrog cov khoom xa tuaj X-ray fluorescence lossis optical emission instruments, yog txoj hauv kev zoo tshaj plaws; thiab kuaj kev soj ntsuam kom paub tseeb tseeb.
Cov khoom ntawm 321 Stainless Hlau Yeeb Nkab
321 yeeb nkab muaj kev tiv thaiv corrosion zoo ib yam li 304, nrog kev ua haujlwm zoo heev rau intergranular corrosion nyob rau hauv qhov rhiab heev vim titanium stabilization. Nws muaj qhov zoo siab - kub lub zog thiab oxidation tsis kam, nrog kev pabcuam txuas mus txog li 870 degrees C, zoo qis - kub toughness mus txog -}200 degrees C, thiab zoo formability thiab weldability. Post{10}}weld annealing feem ntau tsis tas yuav tsum tau tiv thaiv intergranular corrosion nyob ze welds. Nws tsis yog- hardenable los ntawm kev kho cua sov thiab tsis-sib nqus nyob rau hauv lub xeev annealed, ua me ntsis sib nqus thaum txias ua hauj lwm.
316 vs 321 ib
Xaiv 316/316L thaum qhov kev txhawj xeeb tseem ceeb yog tiv thaiv cov chlorides, pitting, thiab crevice corrosion, xws li dej ntsev, los yog thaum xav tau zoo heev cryogenic toughness. Xaiv 321 rau welded Cheebtsam los yog kev pab cuam nyob rau hauv 450 mus rau 800 degrees C qhov twg rhiab heev thiab intergranular corrosion yog txaus ntshai, xws li tso pa system, siab -kub txheej txheem piping, thiab tshav kub exchangers nyob rau hauv uas ntau yam.
Cov lus nug nquag
Q: 1Cr18Ni9Ti sib npaug li cas?
A: Nws yog sib npaug rau UNS S32100 thiab ASTM 321 titanium-stabilized austenitic stainless hlau.
Q: Vim li cas titanium ntxiv rau 321 stainless hlau?
A: Titanium stabilizes lub alloy, tiv thaiv chromium carbide nag lossis daus thiab intergranular corrosion thaum vuam thiab siab - kub raug.
Q: Qhov txawv ntawm A312 thiab 321 yog dab tsi?
A: A312 yog cov yeeb nkab tshwj xeeb uas npog ntau qib; 321 yog ib qho ntawm cov qib teev tseg hauv qab nws.
Q: Yuav ua li cas yog stainless hlau yeeb nkab qhia nyob rau hauv lub teb?
A>Los ntawm kev pom cov cim, daim ntawv pov thawj zeb, cov lus teb sib nqus, tshuaj ntsuam xyuas qhov chaw, thiab kev txheeb xyuas cov khoom zoo nrog XRF lossis OES cov cuab yeej.
Q: Dab tsi kub ntau yog 321 yeeb nkab haum rau?
A: Kev pabcuam txuas ntxiv mus txog 870 ° C nrog oxidation tsis kam, thiab kev pabcuam hauv 450 txog 800 ° C ntau yam tsis muaj qhov txaus ntshai.
Q: Thaum twg 316 yuav tsum xaiv tshaj 321?
A: Thaum chloride pitting thiab crevice corrosion yog qhov kev txhawj xeeb tseem ceeb, xws li hauv cov dej ntsev.
