Introduction to raw materials of alloy steel flange
Alloy steel and carbon steel are two types of steel. Alloy steel is metal alloys of iron, carbon, and high amounts of other elements. The other elements present in it typically include manganese, silicon, nickel, titanium, copper, and chromium. These elements are called alloy elements because these elements are mixed together to form an alloy. The purpose of adding these elements is to improve the properties of steel.
Carbon steel flanges and alloy steel flanges are different kinds of material grades for flanges, although both are extremely common. Alloy steel comes with a variety of elements depending upon future applications. The carbon steel also known as iron-carbon alloy contains less than 2% carbon WC. It usually contains small amounts of carbon, phosphorus, sulfur, manganese, and silicon in the mix.
The main difference between alloy steel and carbon steel is that alloy steel has high amounts of other elements apart from iron and carbon whereas carbon steel has trace amounts of other elements apart from iron and carbon.
In the case of alloy steel, elements like molybdenum, manganese, chromium, nickel, vanadium, silicon, and boron are used to form a different chemical composition. Generally, alloy steels are of the higher nickel variety and the term is used to distinguish them from regular stainless or low chrome materials.
Application of alloy steel flange
Alloy steel flanges come in a broad range of applications. They are widely used in various industries including petrochemical, oil and gas, power generation, bulk liquid transportation, chemicals, pharmaceuticals, pulp and paper manufacturing, textiles, and others.
Alloy steel flanges are classified into two categories, high alloy steel flanges, and low alloy steel flanges.
Low alloy steel flanges have applications in a wide range of industries due to their cost-effectiveness. Low Alloy Steel Flanges contain about 0.05 – 0.25% of carbon along with up to 2.0% manganese. Low alloy steels contain trace quantities of alloys such as niobium, nitrogen, vanadium, copper, nickel, chromium, titanium, calcium, molybdenum, rare earth elements, or zirconium.
Low alloy steel flanges have applications in military vehicles, construction equipment, ships, pipelines, pressure vessels, and oil drilling platforms.
High alloy steel flanges are widely applied in various applications due to their structural components, automotive applications, chemical processing equipment, corrosion resistance, and superior hardness. In order to strengthen the Chromium AS Flanges, its alloy has added elements i.e. Copper, titanium, vanadium, and niobium.
