I-UNS N08020/EN 2.4660/Ingxubevange 20/20Cb-3 Insimbi Engagqwali

I-Nickel Alloy 20 Bar, I-alloy 20 Sheet

I-alloy 20 (UNS N08020) iyinsimbi engagqwali ene-nickel egogekayo ephezulu enokumelana nokugqwala okuphezulu ku-H2SO4 ne-HNO3 nama-asidi ayo axubile. I-alloy 20 inikeza ukumelana nokugqwala okuhle kakhulu futhi isetshenziswe kabanzi embonini yokucubungula amakhemikhali. I-alloy 20 iyingxubevange esekwe ku-nickel-iron-chromium enezengezo zethusi ne-molybdenum. Okuqukethwe kwayo kwe-nickel kusiza ekucindezelekeni kwe-ion ye-chloride kanye nokumelana nokugqwala. Ukwengezwa kwethusi ne-molybdenum kunikeza ukumelana nezindawo ezinobutha, i-pitting, kanye nokugqwala kwemifantu.

I-LKALLOY ingumnikezeli waseChina ohamba phambili embonini wama-alloys ensimbi engagqwali e-nickel esezingeni eliphezulu futhi sithengisa futhi sikhiqiza i-Alloy 20 plate, i-Alloy 200 pipe, Alloy 200 bar, nezinye izinhlobo ezithengiswayo ngosayizi nokucaciswa okuhlukahlukene.
