Understanding 35CrMo Alloy Steel Stud Bolts Characteristics and Applications

In the realm of industrial engineering and construction, the choice of materials plays a crucial role in ensuring the safety, efficiency, and longevity of structures and machinery. One such material that has gained prominence in various applications is the 35CrMo alloy steel. Known for its impressive mechanical properties, 35CrMo is often utilized in manufacturing stud bolts, which are essential components in fastening systems.

What is 35CrMo Alloy Steel?

35CrMo is an alloy steel that contains various elements, including chromium and molybdenum, which enhance its strength and toughness significantly. The 35 in its name refers to the carbon content, while Cr denotes chromium, and Mo indicates molybdenum. This steel exhibits excellent hardness, wear resistance, and tensile strength, making it suitable for demanding applications, particularly in heavy machinery, automotive, and construction sectors.

The typical chemical composition of 35CrMo includes approximately 0.30-0.40% carbon, 0.90-1.20% chromium, and 0.15-0.25% molybdenum. The presence of these elements contributes to its superior mechanical properties such as high yield strength, impact toughness, and fatigue resistance. Moreover, 35CrMo is often tempered and quenched to achieve optimum performance characteristics.
