ʻO nā huahana kila kila he mea kaulana loa i ka wili ʻia e hāʻawi i ke kūpaʻa corrosion maikaʻi no nā ʻano noi he nui.Hoʻohana nui ʻia ka pā kila kila a me ka coil i nā lako o loko, nā paia, nā moku kaomi a me nā noi kai.ʻO 430 ka pā kila kila kūpono no nā lako kaiapuni maloʻo a i ʻole.304 kuhiliʻole
kūpono ka pā kila no nā paia o waho a i ʻole nā puka makani.ʻO 316 ke kila kila kila kūpono no ka ipu kaomi o ka ʻenehana a me nā noi kai.
Ua kapa ʻia ʻo wili kila kila he ʻōwili, ʻōwili mea, ʻōwili pā, ʻōwili pā, me ka paʻakikī nui.Nā hiʻohiʻona kila kila:
1. Nā kikoʻī piha, nā mea like ʻole;
2. Kiʻekiʻe dimensional pololei, a hiki i ± 0.1mm;
3. ʻO ka maikaʻi o ka ʻili maikaʻi, ka mālamalama maikaʻi;
4. Ka ikaika o ka corrosion, ka ikaika tensile kiʻekiʻe a me ka ikaika luhi;
5. Hoʻohui kemika kūpaʻa, kila maʻemaʻe, haʻahaʻa hoʻokomo ʻia;
6. Paipai maikaʻi, kumukūʻai maikaʻi;
7. Hiki ke hana ʻia me ka ʻole calibration.
