SS400 Steel Mechanical Properties
SS400 Steel plate Product Introduction
Mechanical properties, such as tensile strength and yield strength, play a significant role in determining the suitability of both SS400 and mild steel for various applications. These properties are quantified through various techniques including hardness measurements, ductility analysis, and fatigue life evaluation.
Tensile Strength: SS400 exhibits a lower tensile strength compared to mild steel, making it less suitable for applications requiring high stress resistance.
Hardness Measurements: SS400 shows a lower hardness compared to mild steel, an essential factor when considering abrasion resistance.
Impact Resistance: SS400 has a higher impact resistance than mild steel, meaning it can withstand higher shock loads without deformation or damage.
With a comprehensive ductility analysis, it's found that SS400 shows higher ductility compared to mild steel. This property is beneficial in applications where malleability is necessary.
Lastly, fatigue life evaluation reveals that while both materials perform well under cyclic loading, mild steel may show a slightly longer fatigue life.
