Comprehensive Gid pou Nikèl ki baze sou Alloys: Monel 400 (UNS N04400)
Ki sa ki Monel 400?
UNS N04400 oswa DIN W.NR. 2.4360\/2.4361, Monel 400 (ke yo rele tou "Alloy 400") se yon solisyon solid alyaj nikèl-kwiv ki gen gwo fòs ak rezistans ekselan nan yon seri de medya ki gen ladan dlo lanmè, asid idrofluoric, asid silfirik, ak alkal. Alloy 400 tou gen rezistans fò nan estrès korozyon fann ak opoze nan pi dlo dous ak dlo endistriyèl. Monel 400 se lajman ki itilize nan jeni lanmè, chimik ak ekipman pwosesis idrokarbone, tiyo, forgings, rasin, èl, ekipman tiyo, Fastener, ak echanjeur chalè.
Weldability, machinabilite, ak tretman chalè
Monel 400 ka fasilman ansanm ak pwosesis soude ki gen ladan baton metal ak soude (SMAW), gaz tengstèn ak soude (GTAW), ak gaz metal ak soude ak soude (GMAW). Yo ta dwe chwazi filler ki koresponn lan oswa electrodes. Depi Alloy 400 se douser pase pi asye, li ka cho-fòme oswa frèt-fòme nan prèske nenpòt ki fòm pandan D. Anjeneral pale, Monel Alloy 400 pwodwi yo ta dwe rkwit (konplètman rkwit) nan 1470 degre F, ak marinated anjeneral oblije pwodwi yon sifas klere ak pwòp sou alyaj la.
Efè nan pwosesis pousantaj ak sistèm tretman chalè sou UNS N04400 tiyo asye alyaj
Uns n 0 4400 se yon alyaj nikèl-kwiv ak konpozisyon chimik (wt.%), Ni pi gran pase oswa egal a 63%, cu 28%-34%, Mn mwens pase oswa egal a 2.0%, Fe mwens pase oswa egal a 2.5%, Si<0.5%, C<0.3%, S≤0.024%. The alloy has high strength, high corrosion resistance and high wear resistance, is more resistant to reducing medium corrosion than pure nickel, and is more resistant to oxidizing medium corrosion than pure copper; it has good resistance to sulfuric acid and phosphoric acid corrosion, especially good resistance to chloric acid corrosion, and also has excellent corrosion resistance to hot concentrated alkali. Therefore, it is widely used in cutting-edge industrial fields such as petrochemical industry, nuclear industry, and defense industry.
