molybdenum pipe is used as component of electron tubes, heaters of high temperature furnaces, thermocouple retainers, etc. Because of the good high-temperature resistance, molybdenum pipe can be used successively for more than 4 thousand hours in vacuum environment.
A method for making a molybdenum part comprises injection molding a feedstock to form an unsintered part, wherein the feedstock comprises molybdenum powder and at least one binder. The molybdenum powder is desirably in a particle size range of about 0.1 micron to about 4 microns, and more desirably in the range of about 0.1 micron to about 0.5 microns.
The molybdenum powder is heated to a temperature sufficient to cause the binder to melt, forming a paste-like mixture. Then, the mixture is fed through an injection system such as a metal injection mold to form the unsintered molybdenum part.
Injection molded molybdenum parts can have complex three-dimensional shapes which are not readily formed using conventional manufacturing processes. Moreover, the process can be more economical than known processes.
Refractory metals and alloys are highly resistant to heat and have unique physical properties, which makes them useful in a variety of applications that would not be possible with some common metals and alloys. In addition, refractory materials have excellent corrosion and oxidation resistance, making them useful for a wide range of industrial applications.
Chrome moly products are named so due to the presence of the two elements Chromium (Cr) and Molybdenum (Mo). Cr increases the material’s resistance to corrosion and oxidation, while Mo increases its strength at elevated temperatures and improves hardenability. In addition, the presence of Cr and Mo in a chrome moly product enhances its toughness, tensile strength, and creep resistance at elevated temperatures.
