GH3536 (GH536) Nickel-Based Alloy

GH3536 (also designated GH536) is a Chinese Ni-Cr-Fe base solid-solution strengthened wrought superalloy, the domestic counterpart of Hastelloy X (UNS N06002 / 2.4665). With chromium, molybdenum and tungsten additions, it combines good high-temperature strength and oxidation resistance with excellent fabricability and weldability, and is widely used for combustor and hot-section components up to about 900 °C long-term (1000 °C short-term).

Chemical Composition (wt%)

Physical Properties

Mechanical Properties (typical)

Good high-temperature strength and oxidation resistance, with good fatigue performance. Actual values may vary with condition and governing standard.

Oxidation & Corrosion Resistance

• Good oxidation resistance in air below 900 °C;
• Good corrosion resistance in a range of acid, alkali and salt solutions;
• Outstanding corrosion resistance in sulfur-bearing environments.

Key Features

• Chromium, molybdenum and tungsten additions provide good oxidation and corrosion resistance;
• Solid-solution strengthening maintains strength and stability at high temperature;
• Good processing characteristics and excellent weldability.

Melting Process

• Vacuum induction melting (VIM), electroslag remelting (ESR) or vacuum arc remelting (VAR).

Fabrication & Welding

• Hot working: heating at 1150–1200 °C; finish-forging temperature not below 950 °C.
• Welding: good weldability by GTAW (TIG), electron-beam welding, resistance welding and other conventional processes.

Heat Treatment

• Solution treatment: 1080–1120 °C, air cool or water cool.

Typical Applications

• Aerospace: engine combustors, afterburners and guide vanes;
• Petrochemical: reactors, piping, valves and heater / furnace tubes;
• Energy: high-temperature furnace components and heat exchangers;
• Industrial furnaces: radiant tubes and burner components.
