About 3D Printing Nickel-based Alloy IN738 Powder:
Nickel-based Alloy IN738 is oxidation, low expansion, nickel-cobalt-ferrite, aluminum, chromium and niobium addition. The alloy has considerable interest in the aircraft gas turbine designers and material engineers for accommodating and gap control components, such as rings, housings, shields, and seals for compressors, turbines, and exhaust systems.
 
In-738 alloy is a vacuum smelting, vacuum casting, precipitated nickel-based alloy, has excellent high temperature and high-temperature corrosion resistance, better than many low chromium content high-strength high-temperature alloys. Its design provides an alloy for the gas turbine industry that has good creep strength up to 1800 * f and can withstand long exposure to engine-related high-temperature court environments. Alloy IN738 has superior and high temperature lasting Performance is comparable to the widely used alloys 713c, as well as substantially better vulcanization resistance.
The IN738 alloy is usually a vacuum fuse casting process of vacuum homogenization and other high strength, high-temperature nickel-based alloy processes. Typical gtingdom creates 200-400 * F metal overheating exceeded the liquid phase line temperature 1500, 1800 preheating temperature. The situation will vary depending on the size of the part and the shape of the door.

How is 3D Printing Nickel-based Alloy IN738 Powder produced?
The specific step of the production method of the chromium nickel-iron alloy is to use a chrome ore and nickel ore with a mineral heat furnace melt reducing process and a method of smelting a smelting.
The smelting temperature is 1920-1980K. The elements in the two ore are melted at high temperatures. To promote the reduction speed.
Carbon reduction chromium oxide generates the start temperature of 1373K; the reaction temperature of the formation of CR7C3 is 1403 K; the start temperature of CR23C6 is 1448k; the reduction of the start temperature of the reduction to form chromium is 1523K.
The mechanism of iron-element reduction is known that the start temperature of the iron oxide reduction reaction is lower than the CR2O3 reduction reaction. Since chromium is a mug with each other, the reduction reaction is easier, and the chromium in the nickel mine is also reduced to chromium iron.

Application of 3D Printing Nickel-based Alloy IN738 Powder:
The In-738 alloy provides an excellent combination of high heat creep and corrosion resistance, better than high strength super gold with lower chromium content. Inconel 738 is a nickel-based alloy, vacuum casting and precipitated hardening, providing excellent mechanical properties of 1800 ° F (982 ° C).
In general, the cutting performance of the IN-738 alloy is comparable to other high temperatures and high-strength nickel-based allies. Processing and grinding of IN-738 alloy.
The IN-738 alloy is developed to improve the casting performance of large cross-sectional sizes.
Maximum use of IN-738 alloy is an engine component in an industrial gas turbine industry, these components need to withstand high temperatures and thermal stresses as well as corrosion and sulfidation. The alloy is mainly used for gas turbines and jet engine components such as leaves, blades, and integral wheels.

 

Storage Condition of Nickel-based Alloy IN738 Powder:
The damp reunion will affect In738 powder dispersion performance and using effects, therefore, nickel-based alloy IN738 powder should be sealed in vacuum packing and stored in cool and dry room, the nickel-based alloy IN738 powder can not be exposure to air. In addition, the IN738 powder should be avoided under stress.

Packing & Shipping of Nickel-based Alloy IN738 Powder:
We have many different kinds of packing which depend on the nickel-based alloy IN738 powder quantity.
Nickel-based alloy IN738 powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Nickel-based alloy IN738 powder shipping: could be shipped out by sea, by air, by express, as soon as possible once payment receipt.
