E koho i ka 304 a i ʻole 316 kila kila?

ʻO 304 a me 316 mau mea kila kila ʻelua. Aia ka ʻokoʻa ma waena o lākou i kā lākou haku mele a me nā kahua hoʻohana. Loaʻa i ka 316 stainless steel ka chromium a me ka nickel ma mua o ka 304 stainless steel, ka mea i ʻoi aku ka maikaʻi o ke kūpaʻa ʻana o ka 316 stainless steel, ʻoi aku ka maikaʻi i ka media chloride. No laila, ʻoi aku ka maikaʻi o ka 316 stainless steel no ka hoʻohana ʻana i nā kaiapuni me nā koi kūpaʻa corrosion kiʻekiʻe, e like me ke kai kai a i ʻole nā ​​​​hana kemika. Hoʻohana maʻamau ʻo 304 stainless steel i nā noi maʻamau e like me nā lako kīhini, nā mea kūkulu hale, etc.

I ka hiki ana i ka 304 a316 kila kila, hiki iā mākou ke aʻo hou e pili ana i kā lākou mau hiʻohiʻona hana. Ma waho aʻe o kā lākou mea hoʻohui kemika, ʻokoʻa nō hoʻi nā mea kila kila ʻelua i kā lākou mau ʻano mechanical a me ka processability. ʻO 316 kila kila ma ke ʻano he kiʻekiʻe aʻe ka ikaika tensile a me ka ikaika compressive, akā he haʻahaʻa haʻahaʻa paha ka plasticity. Eia kekahi, ʻaʻole maʻalahi nā ʻano hana wela o 316 stainless steel e like me 304 stainless steel, no laila e koi ʻia ka nānā a me nā mākau i ka hana ʻana a me ka hana ʻana. Eia kekahi, aia kekahi mau ʻano mea kila kila ʻē aʻe, e like me 304L a me 316L, he haʻahaʻa haʻahaʻa ka carbon content a ʻoi aku ka maikaʻi no ka pale ʻana i ka hana o nā precipitates i ka wā welding. No laila, i ke koho ʻana i nā mea kila kila, ma waho aʻe o ka noʻonoʻo ʻana i kona kūpaʻa ʻana i ka corrosion, pono nō hoʻi e noʻonoʻo i kona mau ʻano mechanical, ka hana ʻana a me nā pono o nā wahi noi kikoʻī i mea e koho ai i nā mea kūpono loa.
