Kemimi hui o 304 kuhiliʻole kila C ≤ 0.08 Si ≤ 1.00 Mn ≤ 2.00 P ≤ 0.05 S ≤ 0.03 Cr 18.00-20.00 Ni (nickel) 8.00~10.50 -;
ʻO ka hui kemika o 304L stainless steel he% C: ≤ 0.03, Si: ≤ 1.0, Mn: ≤ 2.0, Cr: 17.0 ～ 19.0, Ni: 8.0 ～ 11.0, S: ≤ 0.05.0.
Hiki ke ʻike ʻia ʻo nā mea nui o 304 stainless steel a me 304L stainless steel he 18% chromium (Cr) a me 8% nickel (Ni);ʻO ka ʻokoʻa nui ma waena o lākou ʻo ka 304L stainless steel he haʻahaʻa-carbon 304 kila.Ma keʻano laulā, ua like ke kūpaʻa o ka corrosion o 304L stainless steel me 304 stainless steel, akā ma hope o ke kuʻi ʻana a i ʻole ka hoʻomaha ʻana i ke kaumaha, ʻoi aku ka maikaʻi o ka pale ʻana o ka palena o ka 304L stainless steel.
Ma ke ʻano o ke kumukūʻai, ʻoi aku ka kiʻekiʻe o 304L stainless steel ma mua o 304 stainless steel, a ʻo 304L stainless steel he haʻahaʻa-carbon stainless steel, pili nui i ke kaʻina hana kuʻi.I ka wā e wili ai, hiki i ka 304L ke kila kila ke hoʻemi pono i ka ʻinoʻino.
Wahi a ke kūlana paʻakikī, ʻoi aku ka maikaʻi o 304 stainless steel ma mua o 304L stainless steel, no ka mea, pili pono ka ʻike kalapona i ka paʻakikī o ke kila kila.Eia kekahi, aia nā 304H stainless steel series.Hōʻike ʻo H i ka ʻike kalapona kiʻekiʻe.
Ma keʻano o ka hoʻohanaʻana, 304: 0Cr18Ni9, e like me ke kila me ka nui o nā noi, he maikaʻi ke kū'ēʻana i ka corrosion, ka wela wela, ka ikaika haʻahaʻa haʻahaʻa a me nā mea mechanical;Maikaʻi ka hoʻopaʻa ʻana, ke kulou ʻana a me nā hana wela ʻē aʻe, ʻaʻohe mea hoʻopaʻapaʻa mālama wela (non-magnetic, hoʻohana i ka mahana o - 196 ℃ ~ 800 ℃).Nā ʻatikala o ka hale (Papa 1 a me 2, nā keʻena, nā paipu i loko, nā mea hoʻomehana wai, nā paila, nā ʻauʻau ʻauʻau), nā ʻāpana kaʻa (wipers windshield, mufflers, huahana i hoʻoheheʻe ʻia), nā mea lapaʻau, nā mea kūkulu hale, nā kemika, ka ʻoihana meaʻai, ka mahiʻai, a me nā ʻāpana moku. .
304L: 00Cr19Ni10 he kila C 304 haʻahaʻa.Ma keʻano laulā, ua like kona pale ʻana i ka corrosion me ke kila 304, akā ma hope o ke kuʻi ʻana a i ʻole ke koʻikoʻi koʻikoʻi, ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion;Hiki iā ia ke mālama i ke kūpaʻa corrosion maikaʻi me ka mālama ʻole ʻana i ka wela, a ʻo ka mahana lawelawe ʻo - 196 ℃～ 800 ℃.
Hoʻohana ʻia ia i nā mīkini waho i nā ʻoihana kemika, lanahu a me ka ʻaila me nā koi kiʻekiʻe no ka pale ʻana i ka corrosion palena o ka palaoa, nā ʻāpana wela o nā mea hale a me nā ʻāpana ʻole me ka paʻakikī i ka mālama wela.
