HEAT RESISTING NICKEL-CHROMIUM ALLOY

摘要

The heat resisting alloy of the invention has high resistance to oxidation, carburization and creep at very temperature ? its composition is as follows (in % by weight) : Ni........................ 24 - 53 Or........................ 20 - 44 C.........................0.01 - o.6 Mn........................0.1 - 1.5 Si........................1.3 - 3 No........................0.5 - 3 N.........................0.05 - 0.2 (w + Mo)..................0.2 - 5 Fe........................ 0 - 47 Cu........................ 0 - 5 the minimum copper content in case the alloy contains tungston and less than 40% nickel is at least 0.1% ; the Ni/Cr ratio is between 1.20 and 1.40.
