I loko o ka hale i kēlā me kēia lā, ʻike pinepine mākou i nā huaʻōlelo 316 a i ʻole 304 ma kekahi mau wili kila kila, e kānalua ka naʻau: "316 mau wili kila a me 304 ʻo wai ka maikaʻi?" Makemake paha e hoʻomau i ka loiloi ʻoihana a me ka loiloi mai ka hana piha, ʻoi aku ka maikaʻi o ka 316 stainless steel screw.

ʻO ka loiloi mua o ka haku mele, 316 wili kila ma mua o 304 ʻoi aku ma mua o hoʻokahi mea molybdenum Mo, e hoʻomaikaʻi i ka 316 stainless steel screw corrosion resistance, kiʻekiʻe wela ke kūpaʻa, ka hoʻololi ʻana i ke kaiapuni e lilo i mea ākea. I loko o nā kaiapuni paʻakikī like ʻole i ka ʻoihana, hoʻohana ʻia nā 316 stainless steel screws a me 304 stainless steel screws me nā kikoʻī like. Ma hope o ka hana ʻana, ʻike ʻia nā wili kila kila 304 i kekahi mau wahi ʻōpala a i ʻole deformation, a ʻaʻohe mea ʻino ʻole nā ​​wili kila kila 316.

No ka mea ʻoi aku ka maikaʻi o ka hana piha o 316 stainless steel screws, hoʻohana nui ʻia lākou i ka meaʻai, ʻoihana a me nā mea hana. I mea e hoʻokō ai i ke kūpaʻa corrosion maikaʻi loa, i ke kaʻina hana o ka 316 stainless steel screws, e noʻonoʻo nā mea hana i ka hoʻohui ʻana i ka metala molybdenum, i loaʻa i ke ʻano o ka uea holoʻokoʻa kekahi loli, e hiki i ka waiwai kūʻē corrosion maʻamau. I ka hana ʻana i kekahi mau pahu kemika, e hoʻohana ʻia nā wili kila stainless 316, a ʻaʻole e loli ke ʻano ma hope o ka makani a me ka ua. Ma hope o ka ʻike ʻana i nā ʻoihana like ʻole, ua lilo ʻo 316 stainless steel screws i hoʻokahi o nā lako lako lako o ke kila moana.

ʻOkoʻa a hoʻomaʻemaʻe ʻia ke kila kila, ʻo 316 nā ʻili kila kila i ka austenitic stainless steel material, me ke kōkua o Mo element, kiʻekiʻe ka pale ʻana i ka wela i hiki i 1200-1300 degere, 304 he inoa ʻAmelika o ke kila kila austenitic maʻamau. Nui nā ʻokoʻa i ka pale ʻana i ka corrosion, ke kūpaʻa oxidation, ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa a me ka ikaika tensile. Inā ʻae nā kūlana hoʻokele waiwai, a i ʻole e hoʻohana i nā wili kila stainless 316 e ʻoi aku ka maikaʻi.
