347H ngongo kowiri tira
Ko te Alloy 347H he maitai whakapumau, austenitic, chromium kei roto te columbium e taea ai te whakakore i te rerenga carbide, a, na reira, ko te waikura intergranualr.Ko te Alloy 347 ka whakapumauhia e nga taapiri o te chromium me te tantalum, ka nui ake te ngokingoki me te pakaru o te ahotea i te koranu 304 me te 304L ka taea hoki te whakamahi mo nga whakakitenga kei te awangawanga te whakamaaramatanga me te waikura i waenga.Ko te taapiri o te columbium ka taea hoki e Alloy 347 te pai o te aukati waikura, ahakoa he pai ake i tera o te koranu 321. Ko te 347H te ahua teitei o te hanga waro o Alloy 347 me te whakaatu i te pai ake o te pāmahana teitei me nga taonga ngoki.Ko te Haosteel Stainless inventory inianei kei roto ko Alloy 347/347H (UNS S34700/S34709) i roto i te pepa, i te pepa porowhita, i te pereti, i te pae porohita, i te tukatuka pae papatahi me nga hua tubular.
