Molybdenum in heat-resistant steel

Are you interested in the features of molybdenum in stainless steels from the supplier company AvecGlob? Here you will find the necessary information on this topic.

The role of molybdenum in the properties of stainless steel

Molybdenum primarily increases the corrosion resistance of stainless steels Molybdenum-containing stainless steels tend to be more resistant to corrosion than classes that do not contain molybdenum.

Steel with an increased content of molybdenum is used in more aggressive environments, such as chemical processing plants, or in marine applications. There are many brands of stainless steels with different molybdenum content. The best class for this application is selected based on the corrosive activity of the service environment.

As a large atom, molybdenum increases the elevated temperature of stainless steel due to solid cure. This effect is used in heat exchangers and other equipment with increased temperature, for example in automobile exhaust systems.

Supplier — the company AvekGlob — offers to purchase a range of rolled metal products, made of different grades of molybdenum-containing stainless steels. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.

The role of molybdenum in the microstructure of stainless steels

Molybdenum is a ferrite-forming element. This means that when molybdenum is added to increase the corrosion resistance of austenitic stainless steel, initially an austenite forming element such as nickel or nitrogen must be present in the structure to retain the austenitic structure.

Duplex stainless steels have a mixture of austenitic and ferritic grains in their microstructure; consequently, they have a «duplex» structure.

This effect is achieved by adding a smaller amount of nickel than is necessary for the manufacture of fully austenitic stainless steel.

Molybdenum is mainly used to improve corrosion resistance in austenitic and duplex stainless steels. In austenitic stainless steels, molybdenum contains from two to seven percent, and in duplex [stainless steels — from three to five percent.

Adding one or two percent of molybdenum to the chemical composition of steels of the ferrite class also significantly increases the corrosion resistance and elevated temperature of these stainless steels.

Supplier — AvekGlob Company — offers various kinds of rolled products from stainless molybdenum-containing steels of domestic and foreign production. The products are offered at affordable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
