Similar Materials to SCM435 for Enhanced Mechanical Properties and Applications

Understanding SCM435 Steel Properties, Applications, and Advantages


SCM435 is a chromium-molybdenum alloy steel that is widely used in various industrial applications due to its unique combination of strength, toughness, and resistance to wear and impact. This steel grade is recognized for its excellent mechanical properties, making it ideal for components that must endure high stress and extreme conditions.


Chemical Composition


SCM435 is classified under the Chinese standard for alloy steels. The primary elements in SCM435 include - Carbon (C) Approximately 0.38% to 0.45% - Manganese (Mn) About 0.60% to 0.90% - Phosphorus (P) Maximum of 0.035% - Sulfur (S) Maximum of 0.035% - Chromium (Cr) Approximately 0.80% to 1.10% - Molybdenum (Mo) About 0.15% to 0.25%


The addition of chromium and molybdenum gives SCM435 superior hardenability and improves its overall mechanical strength, particularly at elevated temperatures.


Mechanical Properties


SCM435 steel exhibits impressive mechanical properties, such as - Tensile Strength Typically around 600-800 MPa. - Yield Strength Ranges from 350 to 450 MPa. - Elongation Approximately 15% to 25% in specific conditions, signifying good ductility. - Hardness Depending on heat treatment, SCM435 can reach a hardness level of 28 to 32 HRC.


These properties result in a material that is not only strong but also tough, making it suited for demanding environments.
