He aha ka ʻokoʻa ma waena o nā mea kila kila 301 a me 304?
ʻO 301 he 4% maʻiʻo nickel, 304 maʻiʻo nickel 8.
ʻAʻole ia e holoi ʻia i loko o ka lewa waho like, ʻaʻole ia e ʻōpala i 304, 3-4 mau makahiki, a ʻo 301 e hoʻomaka i ka pala i loko o 6 mau mahina. E paʻakikī ke ʻike i loko o 2 mau makahiki.
ʻO ke kila kila (Stainless Steel) he pōkole no ke kila ʻakika kūpale. ʻO nā kila i kū ʻole i nā mea hoʻoheheʻe nāwaliwali e like me ka ea, ka mahu, a me ka wai, a i ʻole nā kila kuhili ʻole, ua kapa ʻia he kila kila; a me nā mea hoʻopale kemika (e like me ka waikawa, ka alkali, a me ka paʻakai) ʻO ke ʻano o ke kila i ʻānai ʻia ua kapa ʻia ʻo ke kila ʻakika. Ma muli o ka ʻokoʻa o ka haku melemele ma waena o nā mea ʻelua, ʻokoʻa ko lākou pale ʻana i ka corrosion. ʻO ka maʻamau, ʻaʻole kūpaʻa ke kila kuhiliʻole i ka corrosion e ka media kemika, ʻoiai ʻo ke kila ʻakika ka mea maʻamau.
