ʻO ka pā kila kila High Nickel Alloy 1.4876 Corrosion Resistant Alloy
ʻO 1.4876 kahi hopena paʻa paʻa Fe Ni Cr i hoʻoikaika ʻia i ke ʻano mea hoʻoheheʻe wela kiʻekiʻe.Hoʻohana ʻia ma lalo o 1000 ℃.1.4876 corrosion resistant alloy he kiʻekiʻe kiʻekiʻe kiʻekiʻe corrosion kū'ē a me ka maikaʻi kaʻina hana, maikaʻi microstructure paʻa, maikaʻi hana a me ka hana kuʻihao.He mea maʻalahi ke hana ma ka hana anu a me ka wela.He kūpono ia no ka hana ʻana i nā ʻāpana e koi ana i ka mahana kiʻekiʻe a me ka hana lōʻihi ma lalo o nā kūlana corrosive koʻikoʻi.
1.4876 corrosion kū'ē'ōleʻa i maikai stress corrosion māwae māwae, stress corrosion māwae ke kū'ē i loko o ka wai chloride, corrosion kū'ē i ka mahu, ea a me carbon dioxide hui, a me ka maikai corrosion kū'ē i nā meaʻawaʻawa e like me HNO3, HCOOH, CH3COOH a me propionic waikawa.
1.4876 corrosion resistant alloy executive standards aia nā ʻano maʻamau ma nā ʻāina like ʻole.ʻO nā kūlana haole ka mea maʻamau UNS, ASTM, AISI a me ka din, ʻoiai ʻo kā mākou mau kūlana aupuni e loaʻa i ka brand standard GB / t15007, koʻokoʻo maʻamau GB / t15008, pā maʻamau GB / t15009, paipu maʻamau GB / t15011 a me ke kāʻei maʻamau GB / t15012.
Kūlana Kelemānia:1.4876, x10nicralti32-20, American Standard no8800, 1.4876, kūlana aupuni gh1180, ns111, 0cr20ni32fe
Carbon C: ≤ 0.10, silika Si: ≤ 1.0, manganese Mn: ≤ 1.50, chromium Cr: 19 ~ 23, nickel Ni: 30.0 ~ 35.0, alumini al: ≤ 0.15 ~ 0.6, titanium Ti: ≤ 0.6, copper ~ 0.6. : ≤ 0.75, phosphorus P: ≤ 0.030, sulfur s: ≤ 0.015, hao Fe: 0.15 ~ keu.
1.4876 corrosion kū'ē'ōleʻa mea maikai wela hana hana.ʻO ka wela wela o ka hana he 900 ~ 1200 a ʻo ka hoʻokumu ʻana o ka wela wela he 1000 ~ 1150 degere.I mea e hōʻemi ai i ke ʻano corrosion intergranular o ka alloy, pono ia e hele i ka 540 ~ 760 degere sensitization zone i ka hiki.Pono ka hoʻoheheʻe ʻana ma waena o ka hana anu.ʻO 920 ~ 980 ka mahana wela wela.
Density: 8.0g/cm3, ka helu heheʻe: 1350 ~ 1400 ℃, pono wela wela: 500J / kg.K, kū'ē: 0.93, modulus elastic: 200MPa.
1.4876 corrosion kū'ē'ōleʻa i maikai stress corrosion kū'ē i loko o ka wai i loko o ka chloride a me ka haʻahaʻa noonoo NaOH.Hoʻohana nui ʻia ia e hana i nā mea hoʻoheheʻe corrosion ma kahi o 18-8 austenitic steel.Hoʻohana ʻia ia i loko o ke kaomi wai reactor evaporator, kiʻekiʻe wela kinoea cooled reactor, sodium cooled fast reactor heat exchanger a me ka superheated steam pipe i ka ʻoihana mana.Hoʻohana ʻia ia i ka HNO3 cooler, acetic anhydride cracking pipe a me nā ʻano mea hoʻololi wela i ka ʻoihana kemika.
