Hoʻomaka i ka Duplex Stainless Steel

ʻO nā kila stainless Duplex, kaulana no kā lākou hui ʻana o nā ʻano austenitic a me nā ferritic, e kū nei ma ke ʻano he hōʻike i ka hoʻomohala ʻana o ka metallurgy, e hāʻawi ana i kahi synergy o nā pōmaikaʻi ʻoiai e hoʻēmi ana i nā drawbacks inherent, pinepine ma kahi kumu kūʻai hoʻokūkū.

Hoʻomaopopo i ka Duplex Stainless Steel:

ʻO ka mea nui o ka duplex stainless steel ʻo kāna microstructure ʻelua-phase, ka mea maʻamau ka hui pū ʻana o ka austenite a me ka ferrite, e hoʻoulu ana i kahi symbiosis o nā hiʻohiʻona maikaʻi i ka wā e hōʻemi ana i nā nāwaliwali. ʻO ka haku mele ʻana, ʻoiai e pili ana i ka papa kikoʻī, e hoʻopili maʻamau i ke kalapona, manganese, silicon, chromium, nickel, phosphorus, a me sulfur, me nā mea hoʻohui koho e like me ka molybdenum, nitrogen, a me ke keleawe e hoʻomaʻemaʻe hou ana i nā waiwai o ka mea.

Kūlana mōʻaukala o Duplex Stainless Steel:

ʻO ka genesis o duplex stainless alloys e hoʻi i ka manaʻo noʻonoʻo i nā makahiki 1920, e hoʻopau ana i nā ʻoihana hana maoli i ka makahiki 1930. I ka hoʻomaka ʻana i ka hoʻolele ʻana i ka hana a me nā noi kūikawā ma muli o ka ʻike kalapona kiʻekiʻe, ʻo ka holomua ʻana o ka decarburization e ka hopena o 1960s i hōʻike i kahi au hou, e hoʻomaʻamaʻa i ka synthesis o nā haʻahaʻa haʻahaʻa haʻahaʻa me ka chromium a me ka nickel i hoʻopaʻa ʻia, no laila e hoʻomaʻemaʻe i ke koena ma waena o ka ferrite a me ka austenite. ʻO ka hōʻailona o kēia alahele evolutionary ʻo Duplex 2205, kahi hui paionia mai ka waena o 1970s e hoʻomau nei i ke kauoha i ka pili ʻana ma muli o kona kūpaʻa ʻoi aku ka maikaʻi ma mua o nā māka austenitic maʻamau.

ʻO nā pono o ka Duplex Stainless Steel:

ʻOiai ke hoʻokumu ʻana i kahi hapa haʻahaʻa o ka mākeke kila kila, hāʻawi nā duplex alloys i kahi kikoʻī o nā pono vis-à-vis kuʻuna austenitic a me nā hoa ferritic. Ma waena o kēia mau mea maikaʻi, ʻo ia ka ikaika kiʻekiʻe, hoʻonui i ka paʻakikī, a me ka ductility, me ke kū ʻana o ka corrosion e puka mai ana ma ke ʻano he hiʻohiʻona, e hoʻokūkū ana, inā ʻaʻole ʻoi aku ka maikaʻi o nā māka austenitic. Eia kekahi, ʻo ka maikaʻi o ke kumu kūʻai i loko o ke kila duplex, ma muli o ka hoʻohana pono ʻana o nā mea hoʻohuihui, e hoʻolilo iā ia i kahi koho koʻikoʻi ma nā noi like ʻole.

Nā noi o Duplex Stainless Steel:

ʻO ka versatility o ka duplex stainless steel e ʻike i ka resonance ma waena o nā ʻoihana a me nā kāʻei, ma muli o kona kūpaʻa corrosion stellar, hoʻonui i ka ikaika, a me nā ʻano kumu kūʻai. ʻO ka hapa nui, nā hana ma waho a me nā ʻoihana kokoke i kahakai, e hoʻopuni ana i ka ʻeli ʻaila, desalination, a me ka mālama wai, e kū ma ke ʻano he poʻe pōmaikaʻi nui o ke kila duplex. Pēlā nō, hoʻonui ʻia kona pono i ka hana kemika, nā noi moana, nā mea hoʻomalu pollution, a me nā hana kūkulu, e hōʻike ana i kona ʻike nui ʻana i nā ʻāina ʻoihana o kēia wā.
