Kila kohu ʻoleʻO ka huahana i'ōwiliʻia i hanaʻia me ke kila kila, he mau mea maikaʻi loa e like me ke kū'ēʻana i ka corrosion, ke kiʻekiʻe o ka mahana wela, a me ke kū'ēʻana. Hoʻohana nui ʻia nā coils stainless steel i ke kūkulu ʻana, nā lako, nā lako kīhini, nā mea uila, nā kaʻa, nā moku a me nā māla ʻē aʻe.
ʻO nā mea nui o nā wili kila kila e loaʻa nā māka like ʻole o ke kila kila e like me 201, 304, 316, a me nā mea ʻē aʻe. No ka laʻana, he 304 stainless steel coils i ka corrosion resistance a me ka processability, a hoʻohana pinepine ʻia e hana i nā lako kīhini, nā lako, etc.; ʻO 316 mau wili kila kila he kiʻekiʻe ke kūpaʻa corrosion a me ke kūpaʻa wela kiʻekiʻe, a kūpono ia no nā lako kemika, nā kai moana, etc.
ʻO ka hoʻomaʻamaʻa ʻana i ka ʻili o nā wili kila kila e pili ana i nā kaʻina like ʻole e like me 2B, BA, NO.4, etc. Hiki ke koho ʻia nā ʻano hana lapaʻau like ʻole e like me nā pono like ʻole. Eia kekahi, hiki ke ʻoki ʻia, ʻokiʻoki ʻia, huki ʻia a hana ʻia e like me nā koi o ka mea kūʻai aku e hoʻokō i nā pono hoʻohana kikoʻī.
