Heat-resistant steels and alloys
Hastelloy C-4 Nickel alloy.
It is a Nickel-chromium-iron-molybdenum alloy with excellent high-temperature strength, oxidation resistance and processability. The oxidation resistance of the alloy is excellent up to 1040 ° C. This Nickel-based alloy has also proven to be exceptionally resistant to corrosion cracking in the petrochemical industry. The matrix stiffness provided by the molybdenum content leads to high strength in the alloy of a solid solution that has good production characteristics. Although this Nickel alloy is primarily noted for its resistance to heat and oxidation, it also has good resistance to chloride-corrosion cracking, carburization, and excellent resistance to reducing or cement atmospheres. Hastelloy C-4 has good resistance to two common conditions that often lead to early destruction of high - temperature alloys: carburization and nitriding.

Spherical powder
Powder metallurgy is the generic term for the process of making solid components from metal powders using heat and pressure to fuse particles together. Powder metallurgy has several manufacturing technologies:
1). Hot isostatic pressing
2). Injection molding of metals
3). Spark plasma sintering
All of these technologies produce mesh-like components that reduce the amount of machining and stock removal, while reducing production waste.
Thanks to the use of finely dispersed metal powders and ultra-thin layers, it is possible to produce parts of very complex shapes in 3D printing. The ability to form fine meshes and internal channels, or to place material only where it is needed, means that the technology can save material, increase functionality, combine multiple parts into one, and produce parts in a shape that is almost impossible to obtain with other methods.
The main methods of powder preparation have two directions: gas atomization and plasma atomization.
Plasma atomization is carried out to produce a powder from a high-purity reactive metal with a high melting point, for example from a titanium alloy Ti6Al4V. The billet or wire feed is fed to the top of the spray gun. Then it is remelted with a plasma torch; liquid metal solidifies in the fall and forms spherical particles.
Gas atomization is the most common form of metal powder production, where liquid metal is directed under pressure through a nozzle and then separated by a jet of inert gas such as argon or nitrogen. The inert gas solidifies the liquid metal, and spherical particles fall to the bottom of the chamber.
Iron powder- has a high Fe content, including 85% of the total composition. This powder is widely used in the manufacture and manufacture of automotive and industrial parts.
Iron-based alloy powder can be used on the working layer of wear-resistant anti-corrosion parts such as turbine blade, nozzle, wear ring, hydraulic rod.
It is recommended to operate the iron powder in a cool, dry, well-ventilated area away from fire and other heat sources, the relative humidity should not exceed 75%. The packaging must be sealed and not exposed to moisture. It should be stored separately from alkalis, alcohol and the tanks should never be mixed. The storage area should be equipped with suitable material in case of leakage.
Rhenium powder - this powder with 99.9 ~ 99.999% purity and special particle size. Typical amounts are 10 g to 10 kg. Rhenium powder is an important additive for tungsten alloys and nickel-based superalloys. If 3 ~ 30% rhenium powder is added to tungsten or molybdenum, the mechanical properties will be greatly improved. It is estimated that a single F35 jet fighter jet requires 5 kg of rhenium. However, the largest consumer of rhenium is jet engines and catalysts in the chemical industry.
Silver spherical powder - has the highest thermal and electrical conductivity of all metals. It is usually found autonomously or in sulfide or arsenide ores, from which it can be recovered as a cyanide complex, which is subsequently reduced to metal in aqueous solution using zinc. The pure metal is resistant to water and oxygen, but in the air it is exposed to sulfur-containing compounds to form the characteristic black layer of silver sulfide. Let's dissolve in sulfuric and nitric acids.
Some silver salts are light sensitive (eg AgI, AgCl, and AgBr) and are essential for photography. Other uses and industries that use silver include jewelry (both pure metal and a component of various alloys), the electrical industry (for example, in the manufacture of contacts) and glass silvering.
Aluminium powder - The most important property of aluminum powder is an intense exothermic reaction, and when it oxidizes, it finds use in a pyrotechnic process. It is much safer and easier to handle compared to its alternatives. In addition to the safety aspect, aluminum powder, when combined with other compounds, can produce impressive and varied effects when used in fireworks. In the foundry industry, aluminum powder is used as a deoxidizer and exothermic mixture to release the discharged liquid to increase the casting yield.
Сopper powder - is widely used in diamond tools, electro-carbon products, powder metallurgy products, friction materials, chemical catalysts, electronic materials and other industries. Copper powder can be divided into electrolytic copper powder and atomized copper powder.
Copper alloy powder is mainly spherical or spheroidal in shape, with high fluidity and high bulk density. This kind of powder is widely used in powder metallurgy of oil-containing, diamond tools, filters, powder metallurgy products and bearing materials.
Spherical Nickel Powder - They are widely used in various fields. Electrolytic nickel powder and reduced nickel powder are the main materials for powder metallurgy. These powders are commonly used in synthetic diamond tools, cemented carbide, electrometallurgy, mechanical engineering, energy and other industries. Atomized nickel powder is irregular in shape and is mainly used in high specific gravity alloys, diamond diamonds, special welding rods, surface coatings and powder metallurgy parts.
Spherical Molybdenum Powder- FMo-1 is used as raw material for processing large molybdenum plate electric heating element made of molybdenum silicide.
FMo-2 is used as a raw material for processing molybdenum wafers, pierced molybdenum mandrels.
Spherical Tungsten Powder - Tungsten powder is the main raw material for tungsten alloy processing. Pure tungsten powder can be used to produce wire, rod, tube, plate, other processing materials and shaped products. Tungsten powder mixed with other metal powder can be turned into all kinds of tungsten carbide, such as tungsten-cobalt alloy, tungsten-rhenium alloy, tungsten-copper alloy, and high-density tungsten alloy.
Spherical titanium powder - Titanium powder and titanium-based alloy powder have high purity and good density. These are the main powder materials for 3D printing metals (selective melting using a laser / electron beam), key components in the aerospace industry, and biomedical titanium alloy implants (surface treatment).
