S32205 Mea Pono
ʻO ASTM A240/A240M--01 Duplex stainless steel 2205 alloy he duplex stainless steel i haku ʻia me 22% chromium, 2.5% molybdenum a me 4.5% nickel-nitrogen alloy.Loaʻa iā ia ka ikaika kiʻekiʻe, ka paʻakikī o ka hopena maikaʻi a me ka maikaʻi holoʻokoʻa a me ke koʻikoʻi kūloko.ʻOi aku ka ikaika o ka 2205 duplex stainless steel ma mua o ka pālua o ka austenitic stainless steel maʻamau.Hāʻawi kēia hiʻohiʻona i nā mea hoʻolālā e hōʻemi i ke kaumaha i ka wā e hoʻolālā ai i nā huahana, e hoʻolilo i kēia alloy i ʻoi aku ka uku ma mua o 316 a me 317L.He kūpono loa kēia huila no ka hoʻohana ʻana i ka pae wela -50°F/+600°F.No nā noi ma waho o kēia pae wela, hiki ke noʻonoʻo ʻia kēia huila, akā aia kekahi mau palena, ʻoi loa ke hoʻohana ʻia i nā hale welded.
Pono o S32205 Duplex Steel
1. ʻOi aku ka ikaika o ka hoʻoulu ʻana ma mua o ka pālua o ka austenitic stainless steel maʻamau, a loaʻa iā ia nā koi e pono ai.
ʻO ka plasticity lawa.ʻO ka mānoanoa o ka pā o nā pahu waihona a i ʻole nā ipu kaomi i hana ʻia me ka duplex stainless steel he 30-50% haʻahaʻa ma mua o ka austenite maʻamau i hoʻohana ʻia, kahi kūpono e hōʻemi i nā kumukūʻai.
2. He kū'ē maikaʻi loa ia i ke koʻikoʻi o ka corrosion cracking.ʻOi aku ka ʻoi aku o ke kūpaʻa ʻoi aku ka ʻoi aku o ka duplex stainless steel me ka haʻahaʻa haʻahaʻa loa i ke koʻikoʻi o ka corrosion ma mua o ka austenitic stainless steel, ʻoi aku hoʻi i loko o ke kaiapuni i loaʻa nā ion chloride.He pilikia ko'iko'i ka 'ino'ino a pa'akikī ke ho'oponopono 'ia ke kila austenitic ma'amau.
3. ʻOi aku ka maikaʻi o ka corrosion resistance o ka mea maʻamau 2205 duplex stainless steel i nā media he nui ma mua o ka 316L austenitic stainless steel maʻamau, ʻoiai ka super duplex stainless steel he kiʻekiʻe kiʻekiʻe ke kūpaʻa kino, a ma kekahi mau media, e like me ka acetic acid, ʻakika formic Hiki iā ia ke hoʻololi i ke kila kila austenitic kiʻekiʻe, a me nā alloys kū i ka corrosion.
4. Loaʻa iā ia ke kūpaʻa corrosion kūloko.Hoʻohālikelike ʻia me ka austenitic stainless steel me ka like me ka alloy content, ʻoi aku ka maikaʻi o kona ʻaʻahu ʻana i ka corrosion a me ka luhi ʻoi aku ka maikaʻi ma mua o ka austenitic stainless steel.
5. ʻO ka coefficient o ka hoʻonui laina ma lalo o ka austenitic stainless steel, kahi kokoke i ke kila kalapona.He kūpono ia no ka hoʻopili ʻana me ke kila kalapona a he koʻikoʻi koʻikoʻi ka ʻenekinia, e like me ka hana ʻana o nā papa hana a i ʻole nā linings.
6. Inā ma lalo o ka haʻawe ikaika a i ʻole nā kūlana haʻahaʻa haʻahaʻa, ʻoi aku ka nui o ka ikehu absorption ma mua o ka austenitic stainless steel, i loaʻa nā pōmaikaʻi no nā ʻāpana kūkulu e hoʻokō i nā pōʻino hikiwawe e like me ka collision, explosion, etc., a he waiwai hoʻohana pono.
