Ma ke ʻano he ʻāpana koʻikoʻi i nā pili mechanical, pili ka hana o nā mea hoʻopili i ka mea i hoʻohana ʻia. ʻO nā mea paʻa i hana ʻia i nā ʻano mea like ʻole i ko lākou ikaika ponoʻī, ka pale ʻana i ka corrosion, ka pale ʻana i ka mahana, a me ke kumukūʻai, e kūpono ai lākou no nā ʻoihana ʻoihana like ʻole.
ʻO ke kila kalapona ka mea maʻamau i hoʻohana ʻia no nā mea paʻa ma muli o kona kumukūʻai haʻahaʻa, ikaika kiʻekiʻe, a me ka maʻalahi o ka hana ʻana. Hoʻohana maʻamau ʻia ka hao kalapona haʻahaʻa (e like me C1010) no nā bolts maʻamau a me nā nati, me ka pale ʻana i ka corrosion i hoʻonui ʻia e ka wela -dip galvanizing a i ʻole electroplating. Loaʻa ka ikaika kiʻekiʻe ma hope o ka hoʻopiʻi ʻana a me ka hoʻomaʻamaʻa ʻana i ke kila kalapona liʻiliʻi (e like me C1045). Hoʻohana ʻia ke kila kalapona kiʻekiʻe i nā noi kūikawā e koi ana i ka ʻoi aku ka paʻakikī, akā e hōʻike ana i ka ʻoʻoleʻa haʻahaʻa.
ʻO ke kila kila, i hoʻonuiʻia e ka hoʻohuiʻana i nā mea e like me ka chromium, molybdenum, a me ka nickel, hoʻohana nuiʻia i nā noi e koi ana i ka ikaika kiʻekiʻe a me ke kūpaʻa luhi, e like me ka automotive a me ka aerospace. No ka laʻana, ke kila 40Cr, ma hope o ke kinai ʻana a me ka hoʻoulu ʻana, hōʻike i ka ikaika maikaʻi loa a me ke kūpaʻa ʻana a hoʻohana mau ʻia i nā mea paʻa no nā mīkini a me nā mīkini kaumaha.
Kaulana ke kila kuhiliʻole no kona kūpaʻa ʻino a ua hoʻokaʻawale ʻia ʻo ia i ʻekolu ʻano: austenitic (e like me 304 a me 316), martensitic, a me ferritic . 304 stainless steel ua hoʻohana nui ʻia i nā ʻoihana meaʻai a me nā ʻoihana kemika ma muli o kona kūpaʻa maikaʻi ʻana a me ka formability . 316 ke kila kila, loaʻa ka molybdenum a me ka corroride kūpono. Hāʻawi ʻo Martensitic stainless steel (e like me 410) i ke koena o ka ikaika a me ka pale ʻana i ka corrosion a hoʻohana mau ʻia i nā mea hana ʻoki a me nā mea paʻa.
ʻO nā metala ʻole -ferrous e like me ke aluminika, ke keleawe, a me ka titanium alloys kekahi mau mea pono. He māmā nā mea hoʻopaʻa alumini, kūpaʻa -ʻino, a me ka hoʻoheheʻe nui ʻana, no laila kūpono lākou no ka lewa a me nā lako uila. Hāʻawi nā ʻāpana keleawe (e like me ke keleawe) i ka conductivity maikaʻi loa a me ka pale ʻana i ka corrosion a hoʻohana mau ʻia i nā pili uila. Hāʻawi nā mea hoʻopaʻa paʻa Titanium i ka ikaika kiʻekiʻe, -kiʻekiʻe ka wela, a me ka ʻinoʻino, akā he kumu kūʻai a hoʻohana nui ʻia i ka mokulele a me nā mea lapaʻau kiʻekiʻe.
ʻO ka hōʻuluʻulu manaʻo, pono ke koho ʻana i nā mea hoʻopaʻa paʻa i ka noʻonoʻo piha ʻana i nā waiwai mekini, ka hoʻokō ʻana i ke kaiapuni, a me ke kumu kūʻai-pono e hoʻokō i nā pono o nā ʻoihana like ʻole.
