N06600 Nickel Alloy Plate Inconel600 Alloy Steel Plate Solid Solution Strengthening Plate
Inconel600, also known as Inconel Alloy 600, is a high-performance nickel-chromium-iron based solid solution strengthened alloy, which has been widely used in many industrial fields due to its excellent high temperature resistance and corrosion resistance. Its excellent physical and chemical properties and mechanical properties make it an indispensable important material in modern industry.
Inconel600 alloy is a nickel-chromium-iron based solid solution strengthened alloy with good high temperature corrosion resistance and oxidation resistance, excellent cold and hot processing and welding performance, and satisfactory thermal strength and high plasticity below 700℃.
The alloy can be strengthened by cold working, or connected by resistance welding, fusion welding or brazing, and is suitable for making oxidation-resistant parts that bear low loads below 1100℃.
Inconel600 is a solid solution strengthened alloy mainly composed of nickel (content of about 70%-72%), supplemented by chromium (14%-17%) and iron (about 10%), and contains a small amount of cobalt, manganese, silicon and other elements. Its core characteristics include:
High temperature resistance: The melting point is 1354℃-1413℃, and it can be used for a long time at 1093℃. A dense oxide film is formed at high temperature to prevent further corrosion.
Corrosion resistance: It has excellent resistance to oxidizing acids (such as nitric acid, sulfuric acid), chlorides and alkaline solutions.
Mechanical properties: Tensile strength of 550MPa and elongation at break of 40% at room temperature; Yield strength of 140MPa is maintained at 700℃.

The main chemical components of Inconel600 include nickel, chromium and iron. Among them, the nickel content is as high as more than 72%, which provides the alloy with excellent high temperature resistance; the chromium content is between 14% and 17%, which improves the corrosion resistance of the alloy; iron, as an alloying element, can improve the mechanical properties of the alloy. In addition, the alloy also contains a small amount of carbon, manganese, silicon, copper, phosphorus, sulfur and other elements, which play a role in refining grains, improving strength and toughness in the alloy.
In terms of physical properties, the density of Inconel600 is about 8.42g/cm³, which is a heavier metal material. Its melting point ranges from 1354℃ to 1413℃, showing good high temperature resistance. The thermal conductivity gradually increases with the increase of temperature, showing low thermal expansion characteristics, and is suitable for use in high temperature environments.
The corrosion resistance of Inconel600 is particularly outstanding. In oxidizing environments, such as strong oxidizing media such as nitric acid and sulfuric acid, it shows good corrosion resistance. At the same time, the alloy also exhibits excellent corrosion resistance in reducing environments and alkaline solutions. This feature makes it widely used in the chemical and petrochemical industries, such as heat exchangers, reactors, piping systems and other equipment, and can resist corrosion from a variety of chemical media.
In terms of high temperature oxidation resistance, Inconel600 can maintain stable organizational structure and performance under long-term high temperature. It can maintain oxidation resistance at temperatures up to 1180°C, forming a dense oxide film to prevent further oxidation corrosion. This feature makes it particularly suitable for high temperature environments with complex atmospheres, such as aircraft engine turbine components, nuclear reactor components, etc.
In addition, Inconel600 also has good mechanical properties. It can maintain good mechanical strength in both high and low temperature environments. At room temperature of 20°C, its yield strength is 240MPa, its tensile strength is 550MPa, and its elongation at break reaches 40%. At high temperatures of up to 700°C, its yield strength can still be maintained at around 140MPa. This excellent mechanical property makes Inconel600 widely used in aerospace, energy, chemical industry and other fields.
The manufacturing and processing of Inconel600 requires strict control of the alloy composition and processing temperature to ensure optimal performance and microstructure. In the manufacturing process, smelting, forging, heat treatment and cold working are usually used. During the forging process, it is necessary to heat to the plastic temperature range, and then apply pressure to form the desired shape. Heat treatment may be required after forging to eliminate residual stress and abnormal grain growth. During cold working, in order to prevent stress concentration and cracks, a multi-pass small deformation method is usually adopted, and intermediate annealing is performed between multiple passes.
The welding performance of Inconel600 is also excellent. Commonly used welding methods include tungsten electrode gas shielded welding, metal electrode gas shielded welding, submerged arc welding, plasma arc welding and electron beam welding. During welding, in order to prevent the occurrence of thermal cracks, it is recommended to use Inconel 82 or Inconel 182 as filler welding materials. Post-weld heat treatment is necessary, and stress relief annealing is usually performed at 870℃ to 980℃ to improve the strength and toughness of the welded joint.
It is worth mentioning that Inconel600 also has good resistance to stress corrosion cracking. In a stress corrosion environment, it can resist crack expansion and prevent stress corrosion cracking. This feature enables Inconel600 to maintain stable performance in high temperature and corrosive environments and extend the service life of equipment.
