Nānā nui o 321 Pipe kila ʻili
Ma ke ʻano he ʻano hou o SS304, ʻo ke kila kila 321 (SS321) he kila austenitic i hoʻopaʻa ʻia me ka hoʻohui titanium o ka liʻiliʻi he 5 mau manawa o ka ʻike kalapona. ʻO ka hoʻohui titanium e hōʻemi a pale paha i ka sensitization o ka carbide precipitation i ka wā welding a me nā lawelawe ma ke ana wela o 425-815 ° C. Hoʻomaikaʻi pū ia i kekahi o nā waiwai i nā wela kiʻekiʻe. Hāʻawi ʻo SS321 i ke kūʻē kūʻokoʻa i ka oxidation a me ka corrosion a loaʻa ka ikaika kolo maikaʻi. Hoʻohana nui ʻia ia i nā mea hoʻomaʻemaʻe aila, nā paipu moku kaomi, nā mea hoʻomehana super radiant, bellews, a me nā mea hana wela wela.
