Alloy steel flanges

Alloying improves the mechanical properties of steel. The various elements used help improve future applications. Every steel is an alloy, but not all steels are called alloy steels.

However, alloy steel is a standard term for steels to which other elements have been deliberately added in addition to vanadium, silicon, boron, molybdenum, manganese, chromium, nickel and others.

Less common alloying elements include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead and zirconium. Alloy steels offer better properties such as strength, hardness, toughness, abrasion resistance, corrosion resistance, hot hardness and hardenability.
Alloy steel flanges are used in a wide range of applications. Low alloy steel is widely used in various industries due to its cost-effectiveness. It is used in military vehicles, construction equipment, ships, pipelines, pressure vessels and oil drilling platforms.

High alloy steel is used in a wide variety of applications due to its structural components, automotive applications, chemical processing equipment, corrosion resistance and super hardness.
