Product Description

Understanding Inconel 738 Powder

Properties and Composition 

Inconel 738 powder is primarily composed of nickel, chromium, tungsten, and smaller amounts of cobalt, aluminum, and other elements. This alloy’s carefully balanced composition contributes to its extraordinary performance. The high nickel content provides excellent corrosion resistance, while chromium enhances oxidation resistance, making it suitable for high-temperature environments. The addition of tungsten strengthens the alloy and improves its creep resistance at elevated temperatures.

Inconel 718 is a high-strength, corrosion-resistant nickel-chromium material used at -423° to 1300°F. The age-hardenable alloy can be readily fabricated, even into complex parts. Its welding characteristics, especially its resistance to post-weld cracking, are outstanding. Inconel 718 density is 8.71g/cm3 at the room temperature of 300 K. In718 melting temperature is 1430°C, and has properties of  good heat resistance and high temperature resistance.

Inconel 718 powder is a nickel-based superalloy, which is very suitable for applications requiring high strength in the temperature range from low temperatures to 1400°F. In718 also has excellent tensile strength and impact strength. Inconel 718 powder has good oxidation and corrosion resistance at temperatures within the useful strength range of the alloy in the atmosphere encountered in the operation of jet engines and gas turbines.

Inconel 718 powder is a precipitation hardening nickel-chromium-iron alloy containing niobium and molybdenum. It has high strength, good toughness and corrosion resistance in high and low-temperature environments below 650°C. Its state can be solid solution treatment or precipitation hardening state.

Manufacturing Process 

The production of Inconel 738 powder involves a sophisticated manufacturing process. It typically begins with melting and refining the alloy in a vacuum induction furnace or an electric arc furnace under controlled conditions. The molten alloy is then atomized using gas or water jets, resulting in the formation of fine powder particles. These particles are subsequently screened, classified, and subjected to heat treatment to optimize their microstructure and properties.

How we play a role in the industry

HIP Technology

Hot Isostatic Pressing (HIP) technology works by placing the product in a closed container, filling it with inert gas and sintering or densifying the product at a very high temperature (usually close to the forging temperature of the material) and at a very high pressure (usually 100 – 140 MPa). This allows the product to be sintered or densified.

MIM Technology

MIM products can be complex in shape, precise in size, high in strength and produced automatically in large quantities, and can significantly reduce the complexity and cost of traditional metalworking

SLM Technology

SLM, also known as Selective Laser Melting, is similar in principle to SLS in that a laser is used to melt and solidify metal powder in a specified area, which is then moulded in a layer-by-layer stack.

EBM Technology

Electron beam melting refers to a vacuum melting method in which the kinetic energy of a high speed electron beam stream is converted to heat as a heat source for melting metals under high vacuum. The abbreviation is EBM.
