6% Moly is a less widely known metal that has proved itself to be indispensable in heavy industries such as the chemical processing industry and oil & gas market. However, for those in the know, 6% Moly is relied upon time and time again for its unique set of advantageous properties such as its super strength and ability to withstand extremely high temperatures.

As an overview, 6% Moly is a superaustenitic stainless steel which contain at least 6% molybdenum. Different Moly alloys will have different metallurgic compositions. For example, Alloy 6HN (UNS N08367) contains 6 weight percent more nickel (Ni) than alloy 254 (UNS S31254) and the increased nickel content means that the resultant allow has better corrosion resistance and added stability.

In general, 6% Moly alloys have exemplary resistance to a number of chemicals and are particularly appropriate for environments such as brackish water, seawater, pulp mill bleach plants that present a high chloride condition. There are several typical manufacturing specifications including ASTM A213, ASTM A269, ASTM A312 and EN 10216.

Molybdenum has many helpful properties, notably high strength and mechanical stability. Even better than this it manages to keep those properties when the temperature gets hot.
