SAE AMS 5589 GH4169 High-temperature Resistant Pipe For Petrochemical Industry

GH4169 tube is a nickel-based high-temperature alloy tube renowned for its excellent mechanical properties, corrosion resistance, and high-temperature performance. It is commonly used in aerospace, energy, and industrial fields where materials must withstand extreme conditions.

 

Material Composition:

Nickel (matrix), with chromium, molybdenum, iron, niobium, and titanium as the main alloying elements.

High nickel content imparts excellent corrosion resistance and oxidation resistance.

The strengthening effect of niobium and molybdenum enhances its mechanical properties.

 

Corrosion Resistance:

Exhibits excellent oxidation and corrosion resistance in high-temperature and corrosive environments (including acidic and high-salt environments).

 

Heat Treatment:

GH4169 high-temperature tube requires heat treatment (solution annealing, aging treatment) to optimize its mechanical properties and corrosion resistance.
