Chrome Moly Steel

Chrome Moly Plate

There are many chromium molybdenum steel products available, each of which has very different chemical and mechanical properties, but they are often grouped as a single category. Chrome moly is the most common name for this group but other names that are used include chromalloy, croalloy, and Cr-Mo (pronounced “cro-mo”).

ASME SA387  ASTM A387  EN10028-2 

What do chromium and molybdenum do to steel?

The addition to steel of the alloys chromium and molybdenum bring characteristics which are particularly desirable for units operating in high temperatures. Both alloys improve high temperature strength, molybdenum improves high temperature creep strength, both improve hardenability and there are additional benefits from wear resistance, corrosion resistance, and impact resistance. At the same time a chrome moly alloy is relatively easy to fabricate. 

Brown McFarlane and Chrome Moly Plate

The Brown McFarlane range is available from our U.K. service centre in Stoke-on-Trent and from our companies in Dubai and Singapore. As well as being available from stock, steel plate can be cut to size and shape according to your fabrication and design requirements and all work is governed by our independently accredited and regularly audited quality systems to ISO 9001.

Our plates are sourced from the highest quality steel manufacturers in the world and, like all our suppliers, these manufacturers have been vetted and assessed by our procurement team.
