Chromium Molybdenum Alloy, CrMo

Product Information

Chromium molybdenum steel – often shortened to chrome moly – is a type of low alloy steel used in various industries and applications. And the two main alloying elements are chromium (Cr) and molybdenum (Mo). These alloys are typically sorted into one main group, with names such as chrome moly, croalloy, chromalloy, and CrMo often used. Industries where the alloy is common include construction, oil and gas, energy, and automotive.

Properties（Theoretical）

Applications of Chromium Molybdenum Alloy

For instance, the added tensile strength and extra corrosion resistance means chrome moly is ideal for environments with an elevated temperature level (beyond that of simple Mo-based steels). So any industries or applications that operate equipment under high temperatures can benefit from using chromium molybdenum alloys. These industries include oil and gas, energy, automotive, metal production, and forming equipment. 

And with such a high temperature tensile strength and corrosion resistance, CrMo is also effective in salt-water applications.

Examples of equipment that use chrome moly include molds, bicycle tubing, crack shafts, chain links, drill collars, machine shafts and conveyors. The alloy's properties also make it effective in construction and manufacturing. These properties include creep strength, rigidity, hardenability, wear resistance, good impact resistance, ease of fabrication, and the ability to be alloyed in ways that create 'fitness for use' in certain applications.

Packing of Chromium Molybdenum Alloy

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.

ATTs’Chromium Molybdenum Alloy is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
