What is alloy steel?

steel is a metal alloy consisting mainly of iron, except for a small amount of carbon, depending on the degree and quality of the steel. Alloy steel is any type of steel to which one or more elements except carbon have been deliberately added to create the desired physical property or characteristic. The common elements that are added to the production of alloy steel are molybdenum, manganese, nickel, silicon, boron, chrome and vanadium. The difference between these two is defined somewhat arbitrarily. Most of them, however, agree that any steel that is alloyed with more than eight percent of its weight, which is other elements next to iron and carbon, is highly alloy steel. Low alloy steels are slightly more common. The physical properties of these steels are modified by other elements to provide them with greater hardness, durability, corrosion resistance or toughness compared to carbon steel. To achieve such propsityerties, these alloys often require heat treatment. If the carbon content is reducedn to a range of 0.1% to 0.3% and some of the alloying elements are reduced, steel can achieve greater weldability and formability while maintaining the strength that steel is known. Such metals are classified as high strength, low alloy steel.

Maybe the most famous light alloy steel is stainless steel. It is a steel alloy with at least 10% of the chromia content. Stainless steel is more resistant to stains, corrosion and rust than conventional steels. It was discovered in 1913 by Harry Brearley of Sheffield in England, but the discovery was not announced to the world until 1915. Stainless steel is commonly used in tables of tables, jewelry, tracking belts, surgical instruments and also in the Aviation. His well -known shine was also appropriated for many famous architectural designs, such as Gateway Arch in St. Louis, Missouri and the top of the Chrysler building in New York.

all types of alloy steel have alloy elements BTo form carbides or compounds rather than simply mixed with iron and carbon. Nickel, aluminum and silicon are examples of elements that make up compounds in steel. Wolfram and vanadium create carbides that increase the hardness and stability of the finished product.
