High temperature alloy

GH4169 nickel based high-temperature alloy has good performance in high temperature resistance, corrosion resistance, fatigue resistance, etc. Its characteristic is that its working temperature can reach 850 ℃, and it can withstand high temperatures of 1100 ℃ in a very short time.

This article employs a two-step melting process to produce alloy ingots with varying carbon contents. Subsequently, through processes such as forging, solution treatment, testing, and analysis, target alloy forgings are fabricated. The results indicate that when the carbon content in the alloy falls within a specific range, the alloy exhibits both excellent corrosion resistance and superior high-temperature performance. The comprehensive performance of the product meets the requirements for use in China's aerospace, energy, nuclear reactor, and other fields.

GH4169 alloy is a solid solution aging strengthened nickel based deformation high-temperature alloy with γ 'and γ' 'as the main strengthening phases. This alloy has multiple types of elements, high degree of alloying, and good comprehensive properties such as high strength and good plasticity.
