GH35 Alloy properties：

High temperature resistance: GH35 has excellent high temperature stability, and can maintain its strength and corrosion resistance for a long time in high temperature environments. This makes it ideal for high-temperature industrial applications such as the petrochemical, aerospace, and power industries.

Corrosion resistance: Due to the high content of nickel and chromium, Hua Nickel GH35 alloy has excellent corrosion resistance to oxidizing and reducing environments. It is resistant to corrosion by acidic and alkaline media, so it is widely used in the chemical field.

High strength: This superalloy has excellent mechanical strength and retains its structural integrity even at high temperatures. This makes it an ideal material to withstand high temperatures and pressures.

GH35 Uses of alloys：

GH35 alloy is used to make parts such as turbine engine combustion chambers, turbine outer rings and exhaust devices that work below 900°C for a long time. It is also suitable for making all kinds of aviation and aerospace engine flame cylinders, burner jackets, afterburner burners, guide rings and other ring parts.

GH35 Process performance：

Welding process: Hua Nickel GH35 alloy has a greater crack tendency than GH3030 alloy. When using HGGH35 wire, the melt pool fluidity is poor, and HGH3030 and HGH3044 wires can be used. Due to its ease of processing and welding, it is now more commonly used in gas turbine engines, industrial furnaces, and nuclear engineering

Heat treatment: The heat treatment process mainly includes two forms of product rods and plates.
