He aha ka mea e kaulana ai ka 304 vs 316?
ʻO nā kiʻekiʻe kiʻekiʻe o ka chromium a me ka nickel i loaʻa i ka 304 a me 316 stainless steel e hāʻawi iā lākou i ke kūpaʻa ikaika i ka wela, abrasion, a me ka corrosion. ʻAʻole wale lākou i ʻike ʻia no ko lākou kūpaʻa ʻana i ka corrosion, ʻike ʻia nō hoʻi lākou no ko lākou helehelena maʻemaʻe a me ka maʻemaʻe holoʻokoʻa.
ʻIke ʻia nā ʻano ʻelua o ke kila kila ma nā ʻoihana ākea. Ma ke ʻano maʻamau o ke kila kila, ʻo 304 ka manaʻo maʻamau "18/8". Hoʻohana nui ʻia ʻo 304 stainless steel no ka mea paʻa a maʻalahi hoʻi e hana i nā ʻano like ʻole e like me ka pale kila kila, ka pā kila ʻole, ka pahu kila ʻole, a me ka paipu kila ʻole. ʻO ke kūpaʻa ʻana o ke kila 316 i nā kemika a me nā kaiapuni kai i koho nui ʻia i waena o nā mea hana.
Pehea lākou e hoʻokaʻawale ʻia ai?
Hoʻonohonoho ʻia nā papa ʻelima o ke kila kila ma muli o ko lākou ʻano crystalline (pehea i hoʻonohonoho ʻia ai ko lākou mau ʻātoma). Ma loko o nā papa ʻelima, ʻo 304 a me 316 mau kila kila ma ka papa austenitic. ʻO ke ʻano o ka austenitic grade stainless steels e hoʻolilo iā lākou i non-magnetic a pale iā lākou mai ka paʻakikī ʻana e ka mālama wela.

2. Na waiwai o 316 Kuleana kila
Loaʻa i ka 316 ka nui o nā mea kemika a me nā mea mechanical like me 304 kila kila. I ka ʻike maka, ua like nā metala ʻelua. Eia nō naʻe, ʻo ka hui kemika o 316, i hana ʻia me 16% chromium, 10% nickel, a me 2% molybdenum, ʻo ia ka ʻokoʻa nui ma waena o 304 a me 316 stainless steel.

304 vs 316 Kuhili ʻole: Kūʻai wela
He mea nui ka pale ʻana i ka wela e noʻonoʻo ai i ka hoʻohālikelike ʻana i nā māka like ʻole o ke kila kila. ʻO ka hoʻoheheʻe ʻana o 304 ma kahi o 50 a 100 degere Fahrenheit kiʻekiʻe ma mua o 316. ʻOiai ʻoi aku ka kiʻekiʻe o ka hoʻoheheʻe ʻana o 304 ma mua o 316, ʻoi aku ka maikaʻi o ke kūʻē ʻana i ka oxidization ma ka lawelawe intermittent a hiki i 870 ° C (1500℉) a i ka lawelawe mau. ma 925°C (1697℉).
304 SS: Hoʻohana maikaʻi i ka wela nui, akā hoʻohana mau ʻia ma 425-860 °C (797-1580 °F) hiki ke kumu i ka ʻino.
316 SS: Hana maikaʻi loa i nā mahana ma luna o 843 ℃ (1550 ℉) a ma lalo o 454 ℃ (850°F)
ʻOkoʻa kumu kūʻai o 304 Stainless Steel vs 316
He aha ka mea i ʻoi aku ka maikaʻi o 316 ma mua o 304 kila kila?
ʻO ka hoʻonuiʻana o ka nickel content a me ka hoʻohuiʻana o ka molybdenum i 316 eʻoi aku ka maikaʻi ma mua o 304. Ma ka awelika,ʻo ke kumukūʻai o 316 stainless steel 40% kiʻekiʻe ma mua o ke kumukūʻai o 304 SS.
316 vs 304 Stainless Steel: ʻO wai ka maikaʻi?
I ka hoʻohālikelike ʻana i ka 304 stainless steel vs 316, loaʻa iā lāua nā pōmaikaʻi a me nā pōʻino e noʻonoʻo ai i ka wā e hoʻoholo ai i kahi e hoʻohana ai no nā noi like ʻole. No ka laʻana, ʻoi aku ka paʻa o 316 stainless steel ma mua o 304 i ka paʻakai a me nā mea corrosive ʻē aʻe. No laila, inā ʻoe e hana nei i kahi huahana e kū pinepine i ka ʻike ʻana i nā kemika a i ʻole kahi kai moana, ʻo 316 ka koho maikaʻi loa.
Ma ka ʻaoʻao ʻē aʻe, inā ʻoe e hana nei i kahi huahana ʻaʻole pono i ka pale corrosion ikaika, ʻo 304 kahi koho kūpono a hoʻokele waiwai. No nā noi he nui, hiki ke loli maoli ka 304 a me 316.
ʻO Jindalai Steel Group he loea a alakaʻi i ka mea hoʻolako i ke kila a me ke kila kila. E hoʻouna i kāu nīnau a e hauʻoli mākou e nīnau iā ʻoe me ka ʻoihana.
