Vanadium Steel
Vanadium steel is an incredibly strong type of steel alloy which incorporates the use of vanadium within its structure. The addition of vanadium to steel improves many of its physical properties such as ultimate tensile strength, ductility and toughness, making it a very desirable material in a variety of engineering applications.
History of Vanadium Steel
Vanadium’s history within steel dates back to 1821 when it was first isolated by Mexican mineralogist Andres Manuel del Rio. This was followed by Scottish Metallurgist James Harrison in 1832 isolating the element in steel sample taken from the titanic wreckage. Soon after, Sir Henry Bessemer termed the element as ‘vanadium steel’, and it was first used in the production of machine tools, due to its much higher hardness and strength compared to conventional steel.
The Strength of Vanadium Steel
Vanadium Steel has an exceptionally high strength to weight ratio, with improved corrosion resistance and wear resistance when compared to carbon steels. This is due to it being able to form an oxide layer which is firmly attached to the vanadium steel surface, helping it to repel corrosion and other environmental degradations.
These properties make vanadium steel an extremely desirable material for automotive and other transportation applications, as it offers much better strength than lighter materials such as aluminium, without compromising on its weight.
Vanadium Steel’s Applications
Due to its increased strength and resistance to wear, vanadium steel is popular in a variety of engineering applications, most notably automotive and aeronautical. Some of the components it might be used in include pistons, fascias, turbine blades and landing gear. Vanadium steel could also be used in heavy equipment, such as large machine tools and agricultural machinery.
The Challenges of Vanadium Steel
Despite its strength, vanadium steel poses a variety of challenges when working with the material, due to its rigidity. Vanadium steel’s tendency to become brittle and crack when cooled presents difficulties when welding the material, and can limit the use of the component in specific applications.
The Future of Vanadium Steel
Despite the difficulties presented when using vanadium steel, its high strength to weight ratio has positions it as a metal of choice in engineering applications, and one which is sure to remain a staple of industry for some time. As long as advancements in welding and metalworking technology can be made, vanadium steel will remain a metal of choice due to its excellent properties and high strength.
