I kēia manawa i ka kamaʻilio ʻana me nā mea kūʻai aku ua ʻike ʻia ʻo 1.4462 kahi mea a nā mea kūʻai aku Lūkini e hopohopo nei, akā aia kekahi mau hoaaloha no kēia maʻamau ʻaʻole i ʻike hou aku, e hoʻolauna mākou i ke kila kila 1.4462 i kēia ʻatikala no nā mea a pau e hoʻomaopopo.
ʻO 1.4462 kahi mea kila kila, ʻike ʻia hoʻi ʻo ka duplex stainless steel (Duplex Stainless Steel).Loaʻa i kēia mea ke kūpaʻa corrosion maikaʻi a me ka ikaika maikaʻi, e hoʻohana nui ʻia i nā ʻoihana ʻoihana.
ʻO nā kila kila duplex kahi papa kūikawā o nā kila kila nona ka microstructure i loko o nā austenite a me nā ferrite, maʻamau i ka ratio o kahi 50:50 a 40:60.Hāʻawi kēia ʻano duplex i ka mea 1.4462 i kona mau waiwai kūʻokoʻa, e hui pū ana i nā pono o nā austenitic a me nā mea kila kila ferritic.
ʻO nā hiʻohiʻona nui o ka mea 1.4462:
1. ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion: ʻO ka Duplex stainless steel he kūpaʻa maikaʻi i ka corrosion i nā ʻano like ʻole, me nā kaiapuni chloride, ka wela wela, a me nā kūlana acidic a alkaline.
2. Ka ikaika kiʻekiʻe: Ma muli o ke ola ʻana o ka pae ferrite, 1.4462 mea i loaʻa i ka ikaika kiʻekiʻe, e hāʻawi ana i ka pono i nā noi e koi ana i ka ikaika kiʻekiʻe.
3. ʻO ka paʻakikī kiʻekiʻe: ʻO ka microstructure o ka duplex stainless steel e hāʻawi iā ia me ka paʻakikī maikaʻi a me ke kūpaʻa hopena, e hana maikaʻi ana i nā noi haʻahaʻa haʻahaʻa a ma lalo o nā haʻahaʻa hopena.
4. Ka laulā o nā noi: 1. Hoʻohana pinepine ʻia nā mea 4462 i ka ʻoihana kemika, ka ʻenekinia moana, ka ʻoihana ʻaila a me ke kinoea, ka hana meaʻai, ka ʻoihana pepa, a me nā mea hana hana ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe.
1.4462 kahua noi:
1.Pressure moku, kiʻekiʻe kiʻekiʻe ka waihoʻana pahu, kiʻekiʻe kiʻekiʻe paipu pipelines, wela hoʻololi (kemika hana hana).
2.Oil and gas pipelines, nā mea hoʻololi wela.
3. Pūnaehana hoʻomaʻemaʻe wai.
4.Pulp a me nā papa hana pepa, nā mea kanu bleaching, mālama a me nā ʻōnaehana lawelawe.
5.Rotary shafts, press rolls, blades, impellers, etc. i ka ikaika kiʻekiʻe a me ka corrosion.
6. Nā pahu ukana no nā moku a kaʻa paha
7. Mea hana meaʻai
Pono e hoʻomaopopo ʻia ʻoiai ʻoiai ʻo 1.4462 duplex stainless steel i ʻoi aku ka maikaʻi o ka hana ma nā ʻano he nui, pono nō e noʻonoʻo i ke kaiapuni noi kikoʻī a me nā koi i ke koho ʻana i nā mea e hiki ai i nā mea i koho ʻia ke hoʻokō i nā pono o ka hoʻolālā ʻenehana.I ka manawa like, hiki i nā mea hana like ʻole ke hana i nā hoʻololi liʻiliʻi i ka ʻano mea like, no laila ʻoi aku ka maikaʻi o ka nānā ʻana i ka pepa ʻikepili waiwai a me nā kikoʻī ʻenehana i hāʻawi ʻia e ka mea hoʻolako no ka hoʻohana kikoʻī.
