Molybdenum metal can be machined with conventional tools and equipment. However there are some ways that molybdenum differs from medium hard cast iron or cold rolled steel:
Jan 19, 2019· An alloy is a material made by melting one or more metals together with other elements. This is an alphabetical list of alloys grouped according to the base metal of the alloy. Some alloys are listed under more than one element, since the composition of the alloy may vary such that one element is present in a higher concentration than the others.

The choice between high-speed steel and sintered carbide (C2 Grade) depends largely on production quantities. In either case, tool life is shorter than would be expected with steel because molybdenum is considerably more abrasive than steel at the same hardness, and molybdenum has a tendency to chip while being machined.
Jun 19, 2019· Molybdenum steel is a high-strength alloy used across a variety of industries. Steel alloys made with molybdenum are not only stronger and harder, they also are highly resistant to heat and corrosion. Electronics, heavy machine parts, tools and aircraft parts are often made with steel alloys that contain molybdenum.

Dec 13, 2016· What Is Chromoly Steel? Chromoly steel is a type of low alloy steel that gets its name from a combination of the words "chromium" and "molybdenum" – two of the major alloying elements. Chromoly steel is often used when more strength is required than that of mild carbon steel, though it often comes at an increase in cost.
