321 ityhubhu yentsimbi engenanto 304 304L 316 316L 310S 321 Ss ityhubhu yentsimbi engenamthungo
Inkcazo
I-321 iStainless Steel yintsimbi ye-austenitic ezinzileyo ezinzileyo nge-titanium.I-321 iqulethe i-chromium kunye ne-nickel kwaye ukongeza kwi-titanium, ibonelela ngokuphucuka kokumelana nomhlwa kwe-inter-granular.I-321 kwi-non-magnetic ukuxhathisa kwi-corrosion efanayo kuhlobo lwe-304. Le nto isetyenziselwa izixhobo ezidibeneyo ezingenako ukuhlanjululwa.Ukongeza, isetyenziselwa izixhobo ezisebenza phakathi kwe-800 kunye ne-1500 ° F.
I-321 ifumaneka kwibha engqukuva, ipleyiti, umbhobho, iphepha, iityhubhu, ikhoyili kunye nombhobho.Ngayo nayiphi na i-321 yeemfuno zensimbi engenasici nceda ufowunele i-Michlin Metals.Ngolwazi oluthe kratya malunga noku kunye nezinye ii-Austenitic Stainless Steels jonga ividiyo kweso sihloko singezantsi:
Iityhubhu ezingama-321 zentsimbi engenamthungo (GB3087-1999) zikumgangatho ophezulu wekhabhoni yentsimbi eshushu-eqengqelekayo kunye nebandayo etsalwa (iqengqelekisiwe) iityhubhu zentsimbi ezingenamthungo, ezisetyenziselwa ukwenza imibhobho yomphunga eshushu kakhulu, ukubilisa imibhobho yamanzi yeebhoyila ezahlukeneyo zoxinzelelo oluphantsi naphakathi. kunye nemibhobho yomsi eshushu kakhulu, imibhobho yomsi emikhulu, imibhobho emincinci yomsi kunye nemibhobho yezitena ezinzulu zeebhoyila zikaloliwe.
I-321 ityhubhu yensimbi engenastainless: Isetyenziswa kakhulu ekwenzeni uxinzelelo oluphezulu kunye noxinzelelo olungaphezulu kwemibhobho yebhoyili yomphunga, njl. umbhobho woxinzelelo oluphezulu kwaye usebenza kwigesi ephezulu yobushushu kunye nomphunga uya kwenzeka phantsi kwesenzo se-oxidation kunye ne-corrosion, ngoko ke umbhobho wensimbi onamandla okukrazuka okuphezulu, ukuxhathisa okuphezulu kwe-oxidation, Kwaye unozinzo oluhle lombutho, i-hydraulic prop tube.
Iityhubhu ezingama-321 zensimbi ezingenasici zihanjiswa kwimeko yonyango lobushushu.Ukongeza, i-microstructure, ubungakanani beengqolowa kunye ne-decarburization layer yeetyhubhu zetsimbi ezigqityiweyo nazo ziyafuneka.Imibhobho yentsimbi engenamthungo yokugrumba ijoloji kunye nolawulo lokomba lwepetroli;Ukuze uhlolisise ubume bamatye angaphantsi komhlaba, amanzi aphantsi komhlaba, i-oyile, igesi yendalo kunye nemithombo yezimbiwa, ukusetyenziswa kwe-drilling Wells.
