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.

Forged Steel Blocks

Our forged steel blocks are crafted from top-tier materials, carefully processed through the steel forging method. As a result, they exhibit outstanding wear resistance and ductility, rendering them superior to castings. This is particularly advantageous in applications demanding heightened strength and extended service life.
Why purchase Forged Steel Blocks from qilu
Our process ensures a minimum reduction area ratio of 3 to 1, ensuring the highest block integrity.
In contrast to castings or flat-rolled products, the forging process imparts directional grain flow and a refined metallurgical microstructure, enhancing mechanical properties such as impact and tensile strength.
At Qilu, we are your comprehensive forging solution. We go beyond forging, offering value-added services like heat treatment, machining, and rigorous testing to provide you with the ultimate solution.
