Ka wehewehe e pili ana i 321 / 321H mea kila kila a hoʻohālikelike ʻia me 304 maʻamau

ʻO nā 304 a me ka 321 ʻelua he 300 mau kuhili kila kila a he ʻokoʻa iki ko lākou kūpaʻa kūpale. Eia nō naʻe, i nā kūlana kū wela o 500-600 kekelē Celsius, hoʻohana ʻia ka 321 mea kila kila. Hoʻohui ʻia, hoʻomohala kūikawā ʻia kahi kila kūpana wela i waho a ua kapa ʻia ʻo 321H. ʻOi aku ka kiʻekiʻe o kona mau kalapona ma mua o ka 321, like me ka home 1Cr18Ni9Ti. Hoʻohui ʻia ka huina kūpono o Ti i ka kila kila e hoʻomaikaʻi ai i kona kūpaʻa ʻana i ka hoʻowahāwahā intergranular. ʻO kēia ke kumu i ka wā mua o ka hana kila kila, no ka mea ʻaʻole i lawa ka ʻenehana smelting e hōʻemi ai i ka ʻike kalapona i ka hao, hiki wale nō ke hoʻokō i kēia me ka hoʻohui ʻana i nā mea ʻē aʻe. Me ka holomua o ka ʻenehana, ua hiki ke hana i nā ʻano kūpana kolonapona-kalapona a me haʻahaʻa-kalapona. No laila, 304 mau mea i hoʻohana ākea. I kēia manawa, ʻike ʻia nā ʻano o ke kūpaʻa wela o 321 a i ʻole 321H a i ʻole 1Cr18Ni9Ti.

ʻO 304 ka 0Cr18Ni9Ti, 321 ma muli o 304 a me Ti e hoʻomaikaʻi ai i ka maʻamau o ka ʻai intergranular.

ʻO 321 ke kila kila ma Ti kahi e like me kahi mea e hoʻokūpaʻa ai, akā he ʻano ikaika wela ia, ʻoi aku ka maikaʻi ma mua o 316L i ka mahana wela. 321 mea kila kila i loko o nā wai aʻaola o nā ʻano like ʻole, nā mahana like ʻole, keu hoʻi i ka mehana oxidizing Kūpono abrasion maikaʻi, hoʻohana ʻia e hana i nā linings a me ka lawe ʻana i nā paipu no nā ipu waikawa kūpale a me nā pono hana kū ʻole.

ʻO 321 ke kila kila he Ni-Cr-Mo ʻano austenitic kila kila, like kāna hana me 304, akā ma muli o ka hoʻohui ʻana o ka titanium metallic, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana i ka pala ka palena o ka palaoa a me ka ikaika o ka wela. Ma muli o ka hoʻohui o ka titanium metallic, kaohi pono ia i ke ʻano o ka chromium carbide.

321 kuhiliʻole kila i maikaʻi stress Rupture hana a me kiʻekiʻe wela ia'ku (Creep Resistance) stress mīkini mehana i oi aku ma mua o 304 kuhiliʻole kila.
