ʻIkepili o ka Paipu Kila Kila 321
Ma ke ʻano he mana i hoʻololi ʻia o SS304, ʻo ke kila kila kila 321 (SS321) he kila kila austenitic paʻa me ka hoʻohui titanium o ka liʻiliʻi he 5 mau manawa o ka nui o ke kalapona. Hoʻemi a pale paha ka hoʻohui titanium i ka sensitization o ka carbide precipitation i ka wā o ka welding a i nā lawelawe ma ka pae mahana o 425-815°C. Hoʻomaikaʻi pū ia i kekahi o nā waiwai i nā mahana kiʻekiʻe. Hāʻawi ʻo SS321 i ke kū'ē koʻikoʻi i ka oxidation a me ka corrosion a he ikaika kolo maikaʻi. Hoʻohana nui ʻia ia i nā lako hana hoʻomaʻemaʻe aila, nā paipu ipu kaomi, nā mea hoʻomehana super radiant, nā bellews, a me nā lako hana wela wela kiʻekiʻe.

Ikaika Luhi o ka Paipu Kila Kila 321
I nā noi hoʻoikaika, he mea nui hoʻi ka ikaika luhi e noʻonoʻo. A ma kēia ʻano, he ʻoi iki ka maikaʻi o 321 SS ma mua o 304 SS. ʻO nā palena luhi a i ʻole ke ahonui (ikaika i ke kūlou ʻana) o nā kila kila austenitic i ke kūlana annealed ma kahi o ka hapalua o ka ikaika tensile. Hōʻike ʻia nā palena tensile maʻamau a me ke ahonui no kēia mau alloys (annealed) ma ka papa ma lalo nei:

Ka hiki ke hoʻopili ʻia o ka Tube kila kila 321
Loaʻa iā SS321 lāua ʻo TP321 ka hiki ke hoʻopili maikaʻi loa, ʻaʻohe pono o ka hoʻomehana mua ʻana. Pono ka mea hoʻopihapiha e like me ke ʻano akā ʻoi aku ka nui o ka metala. Ka haki ʻana o ka wai ma kahi i hoʻopilikia ʻia e ka wela: hoʻokomo ikehu haʻahaʻa. Ka nui o ka palaoa maikaʻi. Ferrite ≥ 5%.
ʻO nā metala hoʻopihapiha i manaʻo ʻia ʻo SS 321, 347, a me 348. ʻO ka electrode ʻo E347 a i ʻole E308L [mahana lawelawe < 370 °C (700 °F)].
