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.
