S32304 Mea Pono
No ka UNS S32304 ke kila ʻelua-phase maʻamau ʻAmelika, ke kūlana hoʻokō: ASTM A240/A270M-2017
ʻO ka UNS S32304 alloy he duplex stainless steel nona ka 23% chromium a me 4% nickel.ʻO nā waiwai kūpaʻa corrosion o 2304 alloy ua like ia me ka 316L.Eia kekahi, ʻo kona mau waiwai mechanical, ka ikaika hua, ʻelua ʻelua o nā māka austenitic 304L / 316L.ʻO kēia hiʻohiʻona hiki i nā mea hoʻolālā ke hoʻemi i ke kaumaha o nā huahana i ka wā e hoʻolālā ai i nā huahana, ʻoi aku ka nui o nā moku kaomi.
He kūpono loa kēia huila no ka hoʻohana ʻana i ka pae wela -50°C /+300°C (-58°F/572°F).Hiki ke hoʻohana ʻia nā haʻahaʻa haʻahaʻa ma lalo o nā kūlana i kaupalena ʻia (ʻoi loa no nā hale welded).Ke hoʻohālikelike ʻia me 304 a me 316 austenite, ʻoi aku ka ikaika o ka 2304 alloy i ke kūpaʻa koʻikoʻi koʻikoʻi ma muli o kāna microstructure ʻelua-phase, haʻahaʻa nickel content a me ka chromium kiʻekiʻe.
S32304 Nā Wahi Noi
ʻO 2304 duplex stainless steel maikaʻi nā mea mechanical a me ke kino, kū'ē i ka corrosion stress a me nā ʻano corrosion ʻē aʻe a me ka weldability maikaʻi, e hiki ai ke hoʻololi i ka austenitic stainless steel e like me 304, 304L, 316, 316L a pēlā aku.Hiki ke hoʻohana 'ia i loko o ka hana 'ana o amine ho'ōla lako, fermentation lako no ka hydrocarbons, etc. Eia kekahi, hiki ke hoʻohana 'ia e like me ka wela exchangers i loko o ka hana 'oihana, digester preheaters i loko o ka pulp a me ka pepa 'oihana, a me ka noho kaʻaahi papa ma humid. wahi wela a me waho.
1. ʻO ka hapa nui o nā māla i hoʻohana ʻia e 304 a me 316
2. ʻOihana Pulp a me ka pepa (nā pahu, nā pahu pahu pahu, nā pahu wai ʻeleʻele a keʻokeʻo paha, nā mea hoʻonohonoho)
3. ʻO ka hoʻonā hoʻoheheʻe ʻana, ka ʻakika organik (anti-SCC)
4. ʻoihana meaʻai
5. Nā Moku Paʻi (e hoʻemi i ke kaumaha)
6. Ka mining (abrasive/corrosion)
