At present, the turbine boosters used in civil transportation vehicles such as diesel locomotives or automobiles use fine-grained equiaxed superalloy blades. Diesel locomotives are mainly produced by CNR Group. In the field of combat vehicles, currently only the United States uses gas turbines as the power of main battle tanks in the world. The US M1 series tanks are equipped with small gas turbines as power, which is highly efficient. Quick start and high horsepower [6]. Nickel Ni201 Nickel Ni201, Nickel N4|Nickel base alloy

Material description Nickel shows good corrosion resistance in many suan and alkaline environments, and is mostly used in reducing media.

Nickel is characterized by its resistance to corrosion by alkaline media, such as caustic potassium and caustic soda, and is widely used in ion-exchange membrane caustic soda technology. Nickel has good corrosion resistance in dry fluorine. Nickel has also been successfully used in drying and neutralizing at room temperature to 540°C. It can also be used in static hydrofluoric suan solution. Nickel has good mechanical properties in a relatively wide temperature range, is easy to cold work, and has processing characteristics similar to low carbon steel.

Typical working conditions Caustic soda solution with concentration lower than 75% and boiling point below

Application areas Plate heat exchangers, bellows compensator expansion joints, caustic soda, chemical equipment, etc.

Matching welding consumables: plates ERNi-1, plates ENi-1

Supply form

Specification: 0.5mm~20mm

In the development of advanced engines in the world, the amount of high-temperature alloy materials used for nickel Ni201 has accounted for 40% to 60% of the total number of engines. Therefore, superalloy materials are also known as "the cornerstone of advanced engines." In addition, superalloys also play an important role in the power, transportation, and petrochemical industries
