Medium- and High-Alloy Steel Forgings
Medium- and high-alloy steels are frequently employed in applications demanding a balance of strength and toughness. These alloys enhance their properties through the inclusion of elements like carbon, manganese, silicon, nickel, chromium, and molybdenum.
Alloy steel stands as the most frequently utilized metal for forging, primarily due to its superior strength, wear resistance, and toughness when compared to carbon steel forgings. The precise combination of alloys and elements plays a pivotal role in determining the physical strength and properties of the metal.
Furthermore, micro-alloying elements such as vanadium, titanium, and niobium are introduced to create specific combinations of properties, including weldability, strength, toughness, and fatigue resistance. To achieve these enhanced properties, alloy steel forgings are often subjected to heat treatment, commonly referred to as hot forging. Qilu maintains an extensive inventory of alloy steel to meet various industry needs.
