Alloy20 mau ano
ʻO Alloy N08020 he nickel-iron-chromium austenitic alloy me ke kūpaʻa maikaʻi loa i ka hoʻouka ʻana i ka waika, pitting a me ka corrosion crevice a me nā waikawa chloride a me nā kemika, ka corrosion maʻamau a me ka corrosion intergranular.Hoʻohui ka alloy i ke kūpaʻa corrosion maikaʻi loa, ka maʻalahi o ka hana ʻana a me ka hoʻonui ʻana i nā waiwai mechanical.
ʻIke ʻia ʻo Alloy N08020 ʻo Carpenter 20, Incoloy a me 20Cb-3.
ʻO N08020 kahi niobium stabilized haʻahaʻa carbon austenitic nickel-iron-chromium alloy i loaʻa ke keleawe a me ka molybdenum.
• Kū'ē maikaʻi i ka sulfuric acid a me ka phosphoric acid Corrosion
• Kūleʻa maikaʻi i ka corrosion intergranular
'A'ole kū'ē loa i ka pohā ʻino i hana ʻia e nā ion chloride
• Kūleʻa maikaʻi i ka ʻinoʻino o ka lua a me ka ʻā
• ʻO nā mea mīkini maikaʻi ma ka lumi wela a me nā wela kiʻekiʻe a hiki i 500°C (930°F)

N08020 pale ʻino:
Hōʻike ʻo N08020 i ke kūpaʻa ʻino maikaʻi loa i nā hoʻonā wai o ka waikawa sulfuric, ka waikawa phosphoric a me nā ʻakika organik a me kā lākou mau paʻakai.Loaʻa iā ia ka maikaʻi o ka nitric acid corrosion resistance.Ma ka hoʻoponopono ʻana i ka haku mele, hōʻike ʻo ia i ke kūpaʻa maikaʻi loa i nā ʻano ʻino like ʻole e like me ka corrosion intergranular a me ka corrosion stress.Hoʻokomo pū ʻia ka Molybdenum e hōʻoia i ka pale ʻana i ka lua a me ka crevice corrosion.No ka hoʻonui ʻana i ka pale ʻana i ka corrosion, pono e mālama pono ʻia ka mea metala a maʻemaʻe.
Loaʻa i ka N08020 ke keleawe a me ka molybdenum, ka mea e hoʻonui ai i ke kūʻē ʻana o ka mea i nā kaiapuni koʻikoʻi a me ke kūʻē ʻana i ka lua a me ka crevice corrosion.Hoʻohana ʻia ʻo Niobium e hoʻopaʻa i ka mea a hoʻemi i ka ua carbide i ka wā wili.Hiki i kēia ke hoʻohana ʻia nā mea hoʻohana i nā wahi corrosive me ka mālama ʻole ʻana i ka wela ma hope o ka weld.Hoʻonui ka Nickel i ke kūʻē ʻana i ka pohā chloride corrosion.
Nā ʻāpana noi huahana o Alloy20
ʻO Alloy 20 kahi mea hao i hoʻokumu ʻia i ka austenitic alloy i hoʻomohala ʻia e pale aku i ka sulfuric acid corrosion.He kūpaʻa maikaʻi loa ia i ka sulfuric acid corrosion;He kū'ē ikaika ia i ka waika phosphoric, ka waikawa nitric a me ka chloride kaiapuni, chloride stress corrosion, pitting corrosion a crack corrosion.No laila, ua loaʻa i ka alloy 20 ka inoa o ka alloy anti-corrosion.
Loaʻa iā ia ka laulā o nā noi: e like me: kemika, meaʻai, lāʻau lapaʻau, hana mana a me nā ʻoihana plastics e hoʻohana iā ia.ʻO ke kū'ē i ka pitting corrosion a me ka chloride corrosion, stress corrosion pohā pilikia, etc., alloy 20 hoʻohana pinepine ʻia.
