ʻO ke kila kila he ʻano kila. ʻO ke kila ka mea i loaʻa ke kalapona (C) ma lalo o 2%, i kapa ʻia he kila, a ʻoi aku ma mua o 2% he hao. ʻO ka hoʻohui ʻana i ka chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo) a me nā mea ala ʻē aʻe i ka wā o ka hoʻoheheʻe ʻana o ke kila e hoʻomaikaʻi i ka hana o ke kila a hana i ka ʻo ke kila corrosion resistant (ʻaʻohe rust) ka mea a mākou e ʻōlelo pinepine ai e pili ana i ke kila kila.
He aha ka "steel" a me ka "hao", he aha ko lākou mauʻano, a he aha ko lākou pilina?Pehea mākou e ʻōlelo maʻamau ai 304, 304L, 316, 316L, a he aha nā ʻokoʻa ma waena o lākou?
Ke kila: Nā mea hao ka mea nui, ka maʻi kalapona ma lalo o 2%, a me nā mea ʻē aʻe.

Hao: He mea metala me ka helu atomika 26. He ferromagnetism ikaika na mea hao, a he maikai ka plasticity a me ka hoololi.
Ke kila kila: kū i ka ea, ka mahu, ka wai a me nā mea hoʻoheheʻe palupalu nāwaliwali a i ʻole ke kila kila. ʻO nā ʻano kila maʻamau ʻo 304, 304L, 316, a me 316L, ʻo ia nā 300 series steels o austenitic stainless steel.
