INKCAZO
Uhlobo lwe-347 / 347H insimbi engenasici yinqanaba le-austenitic yensimbi ye-chromium, equkethe i-columbium njengento yokuzinzisa. I-Tantalum nayo inokongezwa ukuze kuzuzwe uzinzo. Oku kuphelisa imvula ye-carbide, kunye ne-intergranular corrosion kwimibhobho yensimbi. Uhlobo lwe-347 / 347H imibhobho yensimbi engenasici inikezela ngokunyuka okuphezulu kunye neempawu zokuqhawula uxinzelelo kunebanga le-304 kunye ne-304L. Oku kubenza balungele ukuvezwa kwi-sensitization kunye ne-intergranular corrosion. Ngaphezu koko, ukufakwa kwe-columbium kuvumela imibhobho engama-347 ukuba ibe nokuchasana nokugqwesa okugqwesileyo, nangaphezulu kunemibhobho engama-321 yensimbi engenasici. Nangona kunjalo, i-347H yentsimbi yeyona ndawo iphezulu yekhabhoni ebambela indawo yombhobho wensimbi engenastainless grade 347. Ngoko ke, iityhubhu zentsimbi ezingama-347H zibonelela ngokuphucuka kobushushu obuphezulu kunye neempawu ezirhubuluzayo.
I-347 / 347H IIPROPATI ZE-STEEL STAINLESS TUBE
Okulandelayo ziipropati ze-347 / 347H zemibhobho yentsimbi engenasici ebonelelwa yiArch City Steel & Alloy:
Ukuxhathisa ukonakala:
- Ibonisa ukuxhathisa kwe-oxidation efana nezinye iintsimbi ze-austenitic ezingenasici
- Ikhethwa ngaphezu kwebanga lama-321 kwindawo enamanzi kunye nolunye ubushushu obuphantsi
- Iipropati ezingcono zobushushu obuphezulu kune-304 okanye i-304L
- Ukuchasana okulungileyo kwi-sensitization kwiindawo eziphezulu zokushisa
- Ifanele izixhobo ezidityanisiweyo ezinzima ezingenako ukukhutshwa
- Isetyenziselwa izixhobo ezisebenza phakathi kwama-800 ukuya kwi-150°F (427 UKUYA 816°C)
Ukuwelda:
-
I-347 / 347H imibhobho yentsimbi / imibhobho ithathwa njengeyona idityanisiweyo phakathi kwayo yonke imibhobho yentsimbi yomgangatho ophezulu
-
Zinokudityaniswa zizo zonke iinkqubo zorhwebo
Unyango loBubushushu:
-
I-347 / 347H iityhubhu zentsimbi estainless kunye nemibhobho ibonelela ngobushushu obuphakathi kwe-1800 ukuya kwi-2000 ° F.
-
Banokuba sisiqabu soxinzelelo ngaphandle kwengozi ye-intergranular corrosion elandelayo phakathi koluhlu lwemvula ye-carbide ye-800 ukuya kwi-1500 ° F.
-
Ayinakuqiniswa ngonyango lobushushu
Usetyenziso:
Imibhobho engama-347/347H isoloko isetyenziselwa ukwenziwa kwezixhobo ekufanele zisetyenziswe phantsi kweemeko ezimandundu zomhlwa. Kwakhona, zisetyenziswa ngokuqhelekileyo kumashishini okucoca i-petroleum. Izicelo eziphambili ziquka:
- Iinkqubo zeekhemikhali zobushushu obuphezulu
- Iityhubhu zokutshintsha ubushushu
- Imibhobho yomphunga yoxinzelelo oluphezulu
- Ubushushu obuphezulu bomphunga kunye nemibhobho yebhoyila/imibhobho
- Iinkqubo zokukhupha umthwalo onzima
- Iiheater ezinkulu ezikhanyayo
- Imibhobho yokucoca ngokubanzi
