ʻO ka ʻokoʻa ma waena o 304 a me 316 kila kila

I ke kūʻai ʻana i nā huahana stainless steel, nā huaʻōlelo maʻamau i ukali ʻia e nā helu 304 a i ʻole 316, ʻo kēia mau helu ʻelua e pili ana i ke kumu hoʻohālike o ke kila kila, akā ʻo ka ʻokoʻa ma waena o ke kila kila 304 a me 316, paʻakikī ke ʻōlelo.I kēia lā, e hoʻokaʻawale mākou i nā mea ʻelua i ka kikoʻī mai ke ʻano o ka haku mele ʻana, ka nui, ka hana, nā kahua noi, a me nā mea ʻē aʻe, a manaʻoʻiʻo e loaʻa iā ʻoe ka ʻike maopopo o kēia mau ʻano kila kila ma hope o ka heluhelu ʻana iā lākou.

ʻO #304 stainless steel # a me 316 stainless steel he austenitic stainless steel, ʻo ka ʻokoʻa ma waena o nā mea ʻelua i ka haku mele: 316 stainless steel hoʻomaikaʻi i ka nickel (Ni) ma ka hōʻemi ʻana i ka chromium (Cr) maʻiʻo, a hoʻonui i ka 2% -3% molybdenum (Mo). ), hoʻomaikaʻi nui kēia ʻano i ka pale ʻana i ka corrosion a me ke kūpaʻa ʻana o ke kila kila, no laila ʻoi aku ka maikaʻi o ka hana o 316 stainless steel ma mua o 304 stainless steel.

Eia ka ʻokoʻa ma waena o 304 a me 316:

1. Nā mea hana

ʻO ka hui ʻana o 304 stainless steel i haku ʻia me 18% chromium a ma kahi o 8% nickel;Ma waho aʻe o ka chromium a me ka nickel, ʻo 316 stainless steel kekahi e pili ana i 2% molybdenum.Hoʻokaʻawale nā ​​mea ʻokoʻa iā lākou i ka hana.

2. Paʻa

ʻO ka nui o ka 304 stainless steel he 7.93g / cm³, ʻo ka density o 316 stainless steel he 7.98g / cm³, a ʻoi aku ka nui o ka 316 stainless steel ma mua o ka 304 stainless steel.

3. Hana like ʻole:

ʻO ka mea molybdenum i loko o ka 316 stainless steel e loaʻa iā ia ke kūpaʻa corrosion maikaʻi loa, no kekahi mau mea waikawa, nā mea alkaline, akā ʻoi aku ka hoʻomanawanui ʻana, ʻaʻole e corroded.No laila, ʻoi aku ka maikaʻi o ke kūpaʻa corrosion o 304 stainless steel ma mua o ka 316 stainless steel.

4. Nā noi like ʻole:

ʻO ka 304 stainless steel a me 316 stainless steel nā meaʻai meaʻai, akā no ka mea ʻoi aku ka maikaʻi o ka corrosion resistance a me ka acid and alkali resistance, e hoʻohana hou ʻia ia i kekahi mau lāʻau lapaʻau a me nā kula ʻē aʻe, aʻo 304 stainless steel ʻoi aku ka hoʻohana ʻana i ka lumi kuke. e like me ka papaʻaina, nā kīʻaha kīhini, nā countertops stainless steel a pēlā aku.

5. ʻokoʻa ke kumukūʻai:

ʻOi aku ka maikaʻi o ka hana o 316 stainless steel, no laila ʻoi aku ka maikaʻi o ke kumukūʻai ma mua o 304 stainless steel.

Loaʻa i nā mea ʻelua i kā lākou mau hiʻohiʻona ponoʻī, a pehea e koho ai ma muli o ke koi maoli.ʻOiai ʻaʻole ʻoi aku ka maikaʻi o ka 304 stainless steel i ka 316, ua lawa kāna hana e hoʻokō i nā pono o kēlā me kēia lā, a ʻoi aku ka maikaʻi o kāna kumukūʻai, no laila ʻoi aku ka maikaʻi.Inā loaʻa kahi koi kiʻekiʻe no ka hoʻohana ʻana, a laila hiki ke koho ʻia ʻo 316 stainless steel e kūpono i nā pono o ka manawa.

E hōʻuluʻulu i nā hiʻohiʻona hana o nā mea ʻelua, stainless steel 304 acid resistance, alkali resistance, high density, polishing without bubbles, high toughness, good processing performance;Ma waho aʻe o nā hiʻohiʻona hana o 304 stainless steel, 316 stainless steel ka mea kūʻē i ka corrosion medium kūikawā, hiki ke hoʻomaikaʻi i ka pale ʻana i ka corrosion i nā kemika hydrochloric acid a me ka moana, a hoʻomaikaʻi i ke kūʻē ʻana i ka brine halogen solution.
