Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4565 / Alloy 24

Siab zog thiab zoo toughness:Muab kwv yees li ob npaug ntawm cov khoom muaj zog ntawm 316 stainless hlau thaum tuav cov kev cuam tshuam zoo heev, txawm tias qhov kub thiab txias.

Zoo heev Corrosion Resistance:Muaj kev tiv thaiv corrosion zoo tshaj rau 316L hauv ntau qhov chaw, nrog kev ua haujlwm zoo dua rau chloride pitting thiab crevice corrosion (PREN feem ntau 32-35).

Zoo hnav thiab Galling Resistance:Ua tau zoo nyob rau hauv kev sib cuag daim ntaub ntawv, xws li bearings, bushings, thiab valve Cheebtsam, vim nws siab ua hauj lwm hardening tus nqi.

Tsis yog-Magnetic:Tseem tseem ceeb tsis yog- sib nqus txawm tias tom qab ua haujlwm txias txias, ua rau nws haum rau kev ntsuas thiab kev siv kho mob.

 

Cov ntawv thov tseem ceeb:

Aerospace:Fasteners, landing gear Cheebtsam, thiab siab -stress structural parts.

Tubrog nkoj:Ncej, twj tso kua mis, li qub, thiab fittings nyob rau hauv seawater ib puag ncig.

Kev ua tshuaj lom neeg:Siab - cov khoom muaj kev ntxhov siab raug rau cov xov xwm corrosive.

Roj & Roj:Cov cuab yeej downhole, cov khoom siv lub taub hau zoo, thiab siab - cov twj tso kua mis.

Kev kho mob:Cov cuab yeej phais thiab cov khoom cog.

Pulp & Ntawv:Cov kws kho mob hniav, cutter tuav, thiab hnav cov khoom.

 

Alloy 24 (1.4565) piv rau 17-4PH (1.4542) li cas?
Alloy 24 yog austenitic stainless hlau ntxiv dag zog los ntawm nitrogen, thaum 17-4PH yog martensitic nag lossis daus- qib hardening. Alloy 24 muaj kev tiv thaiv corrosion zoo dua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride, thiab tswj nws cov khoom ntawm qhov kub thiab txias. Nws tseem tsis yog-sib nqus, thaum 17-4PH yog sib nqus. 17-4PH tuaj yeem ua tiav cov tawv tawv dua thiab lub zog los ntawm kev laus (txog 44 HRC vs. 28 HRC rau Alloy 24) tab sis tej zaum yuav muaj kev cuam tshuam ntau dua rau kev ntxhov siab corrosion cracking. Alloy 24 muaj qhov zoo dua weldability yam tsis muaj kev kho cua sov tom qab vuam thiab zoo dua toughness. Qhov kev xaiv nyob ntawm daim ntawv thov: Alloy 24 rau corrosion kuj thiab toughness, 17-4PH rau siab tshaj plaws thiab hardness.

 

Dab tsi yog qhov kev txiav txim siab machining rau Alloy 24?
Alloy 24 muaj qhov ua haujlwm siab ua haujlwm siab, uas tuaj yeem ua rau kev ua haujlwm nyuaj dua li cov qib austenitic. Cov kev coj ua uas pom zoo suav nrog kev siv cov txheej txheem nruj, cov cuab yeej txiav ntse, kev nrawm nrawm thiab pub, thiab ua kom txias txaus. Nws yog feem ntau machined nyob rau hauv lub annealed mob. Txawm tias nws lub zog siab, nws tuaj yeem ua tiav nrog cov txheej txheem tsim nyog. Rau tapping thiab threading, tshwj xeeb tsim cov cuab yeej yuav tsum tau vim nws nyiam ua hauj lwm harden. Cov khoom teb zoo rau kev sib tsoo thiab polishing, ua tiav qhov zoo tshaj plaws ntawm qhov tiav.

 

Qhov kub ntau npaum li cas yog Alloy 24 haum rau?
Alloy 24 yog tsim rau ntau qhov kub thiab txias los ntawm cov kab mob cryogenic mus txog 350℃(662℃F) rau kev pabcuam txuas ntxiv. Nws cov ntsiab lus nitrogen siab muab lub zog zoo khaws cia ntawm qhov kub siab, thaum nws cov qauv austenitic ua kom muaj zog zoo ntawm qhov kub thiab txias mus rau -196℃. Rau cov ntawv thov uas yuav tsum tau muaj peev xwm kub siab dua, lwm cov qib yuav tsim nyog dua. Lub alloy tuav zoo corrosion kuj mus txog 300 degree, saum toj no uas ntev ntev yuav cuam tshuam cov khoom.
