321 bir ah 8*1 mm tube duuban
Alloy 347H waa xasiloon, austenitic, bir chromium ka kooban columbium kaas oo u ogolaanaya in la baabi'iyo roobab carbide, iyo, sidaas awgeed, daxalka intergranualr.Alloy 347 waxaa lagu xasiliyay isku darka chromium iyo tantalum wuxuuna bixiyaa gurguurta iyo kadeedka guryaha dillaaca marka loo eego alloy 304 iyo 304L kuwaas oo sidoo kale loo isticmaali karo soo-gaadhista halka dareenka iyo daxalka intergranualr ay walaac ka qabaan.Ku darida kolumbium waxay sidoo kale u ogolaataa Alloy 347 si ay u yeelato iska caabin aad u fiican, xitaa ka sarreeya tan 321.Haosteel Stainless Inventory hadda waxaa ku jira Alloy 347/347H (UNS S34700/S34709) ee xaashida, gariiradda xaashida, saxan, bar wareeg ah, bar fidsan oo la warshadeeyey iyo alaabada tuubada.
