GH3536、GH536

GH3536 overview

The superalloy GH3536 is a nickel-chromium-molybdenum alloy with cobalt and tungsten added. GH3536 alloy has excellent oxidation resistance at high temperatures up to 1200 ° C, and can also be used in neutral and reducing atmospheres. At the same time, GH3536 alloy can resist carbonization and nitriding atmosphere.

GH3536 melting temperature range

Melting temperature range: 1260 ～ 1355 ℃

 

GH3536 has the following features

● Excellent oxidation resistance up to 1200 ℃

● Good high temperature strength

● Good formability and weldability

● Good resistance to stress corrosion cracking

 

GH3536 application areas

Due to its corrosion resistance in various atmospheres at high temperatures and excellent high-temperature strength, GH3536 has been widely used in various high-temperature environments.

 

Typical application areas:

● Industrial and aviation turbines (combustion chambers, rectifiers, structural covers)

● Industrial furnace parts, support rollers, grids, ribbons and radiant tubes

● Spiral tube in petrochemical furnace

● High-temperature gas-cooled nuclear reactor

 

GH3536 welding

GH3536 can be welded by various welding processes, such as tungsten electrode inert gas shielded welding, plasma arc welding, manual sub-arc welding, metal extremely inert gas shielded welding, and molten extremely inert gas shielded welding. Preference is given to pulsed arc welding.

Before welding, the material must be in the solution treatment state to remove oxide scale, oil stains and various mark marks. The width of each side of the weld is about 25mm, and it needs to be polished to a bright metal surface.

With low heat input, the inter-layer temperature does not exceed 100 ° C.

No pre- and post-weld heat treatment required
