UNS N08020

ʻO UNS N08020, ka mea i kapa ʻia ʻo Alloy 20 kekahi o nā "super" stainless steels i hoʻomohala ʻia no ke kūpaʻa kiʻekiʻe i ka hoʻouka ʻana i ka waikawa, no kēia mea, aia nā ʻano hoʻohana like ʻole no ia mea ma nā ʻoihana stainless a me nickel. Me he mea lā e hāʻule ana ka Alloy 20 ma waena o nā ʻano ʻano ʻili a me ka nickel, no ka mea, aia nā ʻano o nā mea ʻelua; akā naʻe, ʻike ka ʻōnaehana helu hui (UNS) iā ia ma ke ʻano he nickel based alloy, no laila ka helu UNS N08020.

ʻO Alloy 20 kahi mea hoʻohui nickel-iron-chromium austenitic me nā hoʻohui o ke keleawe a me ka molybdenum. ʻO kāna ʻike nickel e kōkua i kāna koʻikoʻi ion chloride a me ka pale ʻana i ka corrosion. ʻO ka hoʻohui ʻana o ke keleawe a me ka molybdenum e hāʻawi i ke kūʻē ʻana i nā wahi ʻino, pitting a me ka corrosion crevice. Hoʻohui ʻo Chromium i kona kūpaʻa ʻana i nā kaiapuni oxidizing, e like me ka nitric acid, a me ka columbium (a i ʻole niobium) e hōʻemi i nā hopena o ka ua carbide. Hiki ke hoʻohana ʻia ka hapa nui o nā ʻano kuʻihao i ka wā e hana ai me Alloy 20, koe wale no ka wili oxyacetylene. Hiki ke hana ʻia me ka wela me ka hoʻohana ʻana i nā ikaika like i koi ʻia e hana wela i nā kila kuhili ʻole austenitic. Ma nā ʻōlelo o ka mīkini, hiki ke hoʻopau maikaʻi ʻia me ka hoʻohana ʻana i ka hoʻonohonoho like a me nā wikiwiki kaʻina i hoʻohana ʻia no nā kila stainless austenitic, e like me Stainless Steels 316 a i ʻole 317.

ʻO nā ʻoihana e hoʻohana ana i ka Alloy 20 me:

• Kemika
• ʻO ka hoʻoheheʻe ʻana o ke kinoea
• ʻO ka hana meaʻai
• Ka lawelawe ʻana i ka wai ʻoihana
• Hoʻomaʻemaʻe metala
• Huihui
• ʻAla ʻaila
• Nā lāʻau lapaʻau
• Pickling
• Pākīpika
• Kaʻina paipu
• Nā mea hoʻoheheʻe
• fiber synthetic
• Pāpaʻa synthetic

ʻO nā huahana i kūkulu ʻia a i ʻole i kūkulu ʻia o Alloy 20:

• ʻO nā pumps Centrifugal
• Nā pahu hoʻomalu
• ʻO nā pahu kinipōpō cryogenic
• Nā hoʻololi pae lana
• Nā hoʻololi kahe
• Nā pahu hoʻomaha kaomi
• ʻO nā paila kaʻina hana Rotary
• ʻO nā ʻeke ʻeha ʻāwili
• Nā kānana
