Eia kahi hoʻohālikelike kikoʻī o 304SS a me 316L mau hose metala kila kila:
ʻO ka haku melemele
ʻO 304SS stainless steel ka mea nui i haku ʻia me ka chromium (ma kahi o 18%) a me ka nickel (ma kahi o 8%), e hana ana i ke ʻano austenitic, me ka maikaʻi o ka corrosion kūpaʻa a me ka processability.
316L kuhiliʻole kila hoʻohui molybdenum i 304, maʻamau i loaʻa chromium (ma kahi o 16-18%), nickel (ma kahi o 10-14%), a me molybdenum (ma kahi o 2-3%). ʻO ka hoʻohui ʻana o ka molybdenum i hoʻomaikaʻi maikaʻi i kona kūʻē ʻana i ka chloride corrosion, ʻoi aku hoʻi i loko o ke kaiapuni i loaʻa nā ion chloride.
ʻO ke kūpaʻa ʻino:
ʻO 304SS ke kila kila maikaʻi ke kūpaʻa ʻino i ke kaiapuni maʻamau a me ka hapa nui o nā kemika, akā hiki ke hoʻohālikelike ʻia kona kūpaʻa ʻana i kahi ʻakika a i ʻole ka paʻakai.
ʻOi aku ka paʻa o 316L stainless steel i nā ion chloride a me nā ʻano media kemika ma muli o kāna ʻike molybdenum, ʻoi aku hoʻi i ka moana kai a me nā noi ʻoihana kiʻekiʻe salinity.
Noi:
Hoʻohana nui ʻia ʻo 304SS stainless steel hose i ka kemika, ka ʻaila, ka mana, nā mīkini a me nā ʻoihana ʻē aʻe, no ka lawe ʻana i ka wai, ka aila, ke kinoea a me nā media ʻē aʻe. Ma muli o kāna hana piha maikaʻi, hoʻohana pinepine ʻia i nā mea kīhini, nā mea hana meaʻai a me nā māla ʻē aʻe.
Ma muli o kona kūpaʻa maikaʻi a me ka ikaika, hoʻohana pinepine ʻia ʻo 316L stainless steel hose ma nā wahi e koi ana i nā mea hou aku, e like me ka pilina pipeline no nā mea hana kemika, ʻōnaehana halihali no nā lako lāʻau lapaʻau, ʻenehana moana, etc.
Nā waiwai kino:
Loaʻa iā lāua ka ikaika kiʻekiʻe a me ka paʻakikī, akā ʻoi aku ka ikaika o 316L stainless steel a ʻoi aku ka ikaika o ka wela ma muli o ka hoʻonui ʻana o nā mea hoʻohuihui.
ʻOi aku ka maikaʻi o ka oxidation a me ka creep resistance o 316L stainless steel ma mua o 304SS i ka wela kiʻekiʻe.
Kumukuai:
No ka mea, ʻoi aku ka nui o ke kila kila 316L a me nā waiwai ʻoi aku ka maikaʻi, ʻoi aku ka kiʻekiʻe o kāna kumukūʻai hana ma mua o 304SS, no laila ua kiʻekiʻe ke kumukūʻai mākeke.
Mīkini a hoʻokomo:
Loaʻa iā lāua ʻelua ka hana machining maikaʻi, a hiki ke hana ʻia ma ke kulou ʻana, ʻokiʻoki a me ke kuʻi ʻana.
Ma ke kaʻina hana, pono nā mea ʻelua e mālama e pale i ka hopena ikaika a i ʻole ke kaomi ʻana, i ʻole e hōʻino i nā lako ponoʻī.
Aia nā ʻokoʻa koʻikoʻi ma waena o 304SS a me 316L mau mea kila kila ma nā ʻano he nui. Ma waho aʻe o ka noʻonoʻo ʻana i ke kumukūʻai, pono e kaulike ke koho i ke ʻano noiʻi kikoʻī, ʻano media, a me nā koi hana. No ke kaiapuni maʻamau a me ka media, hiki i ka 304SS ke koho waiwai a kūpono, aʻo 316L paha i kūpono i nā wahi kahi e koi ʻia ai nā koi kiʻekiʻe no ka pale ʻana i ka corrosion a me ka ikaika.
