Audited Supplier 1. Introduction to GH5188:
GH5188 is a solid solution strengthening cobalt-based superalloy. It is strengthened by adding 14% tungsten in the solution treatment, so it has high temperature thermal strength. GH5188 superalloy has a high chromium content and a small amount of lanthanum, so it has strong high-temperature oxidation resistance, and good welding and plastic properties. ) and anti-oxidation (below 1100ºC) parts.

6. GH5188 application range
Representative applications: aero-engine combustion chamber flame tubes and guide vanes, as well as high-temperature components such as missiles, combustion chambers, tail nozzles, and heat exchangers in the nuclear energy industry. In order to prevent the corrosion resistance and mechanical properties of GH5188 from being damaged, care should be taken to avoid copper contamination and carburization in any process such as heat treatment and welding.
