2. Mechanical Properties of SCM440H Steel

Upon examining the mechanical properties of SCM440H, it becomes evident that this steel meets all technical standards required for manufacturing industrial machinery components.

The mechanical properties of SCM440H are critical factors in evaluating its performance and suitability for various applications.

a. Tensile Strength

First, regarding tensile strength, SCM440H has a strength of 655 MPa (approximately 95,000 Psi). With such standard values, SCM440H exhibits excellent durability, ensuring ease of machining without concerns about breaking under external pressure or environmental conditions.

b. Yield Strength

In terms of yield strength, SCM440H reaches 930 N/mm², indicating that it can be easily melted at a certain threshold, making it ideal for casting, mold-making, and machining according to specific requirements.

c. Elongation Capacity

Elongation refers to the material's ability to change length after being stretched to the breaking point. SCM440H has an elongation at break (over 50mm) of 25.7%, demonstrating that it can withstand external forces without breaking while maintaining its shape once the force is removed.

d. Hardness

Hardness is a measure of a material's ability to resist localized deformation when subjected to external force. The pre-heat-treated hardness of SCM440H round bars ranges between 22HRC – 32HRC.

After heat treatment, the hardness can reach 50HRC – 55HRC, showcasing excellent wear resistance. Higher hardness values correlate with improved resistance to abrasion.

Understanding the mechanical properties of SCM440H helps optimize its application in real-world products. Sevit is committed to providing customers with high-quality steel products widely used in manufacturing and industrial production.

We firmly believe that SCM440H meets both quality and cost-effectiveness, ensuring customer satisfaction and cost savings for businesses.
