Iityhubhu zeNickel Alloy 20 • UNS N08020 • 2.4660

Inkcazo emfutshane:

Iityhubhu ze-Alloy ze-Nickel ze-Alloy ezingama-20. I-Alloy 20 yi-alloy ye-nickel-iron-chromium eyongezwe ubhedu kunye ne-Molybdenum. Izinzile nge-niobium ngokuchasene nokuziva kwaye iphumela ekuqhekekeni kwe-intergranular. I-Alloy 20 inokumelana okuhle nokubola okuqhelekileyo, ukugawulwa kwemigodi kunye nokuqhekeka kwimichiza equlethe ii-chloride kunye nee-sulfuric, phosphoric kunye ne-nitric acids.
