1. ʻO ka maʻiʻo o nā mea hoʻohui.
ʻO ka ʻōlelo maʻamau, ʻaʻole hiki ke ʻōpala ke kila me ka maʻi chromium o 10.5%.ʻOi aku ka kiʻekiʻe o ka chromium a me ka nickel, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion, e like me 304 mau mea nickel ma 8-10%, chromium maʻiʻo o 18-20%, ʻo ia ʻano kila kila ma ka laulā ʻaʻole ʻōpala.
2, ʻo ke kaʻina hoʻoheheʻe ʻana o ka ʻoihana hana e hoʻopilikia pū i ka pale ʻana o ke kila kila.
He maikaʻi ka ʻenehana hoʻoheheʻe ʻia, nā mea hana kiʻekiʻe, ke kaʻina hana o ka mea kanu kuhili ʻole nui inā i ka mana o nā mea hoʻohuihui, ka hoʻohemo ʻana i nā haumia, billet cooling temperature control hiki ke hōʻoiaʻiʻo ʻia, no laila ke kūpaʻa a hilinaʻi ka maikaʻi o ka huahana, maikaʻi kūloko maikaʻi, ʻaʻole maʻalahi. ʻōpala.ʻO ka mea ʻē aʻe, ua hoʻi hope kekahi mau mea kila liʻiliʻi, ke kaʻina hope, ke kaʻina hoʻoheheʻe, ʻaʻole hiki ke wehe ʻia nā mea haumia, ʻo ka hana ʻana o nā huahana inevitably rust.
3, ke kaiapuni o waho, ua maloʻo ke aniau a ʻaʻole maʻalahi ka ʻōpala.
A he nui ka haʻahaʻa o ka ea, ua mau ka ua, a i ʻole ke kaiapuni me ka acidity nui i ka lewa e maʻalahi ka pala.304 mea kila kuhiliʻole, inā ʻilihune loa ka pōʻaiapuni e pala.
