Unveiling FGE 38-17 Steel Grade: The Ultimate Solution for High-Stress Applications

Specification:

FGE 38-17 is a high-strength steel grade specifically designed for high-stress applications. It offers exceptional mechanical properties and chemical composition that make it the ultimate solution for demanding environments.

Mechanical Properties:

– Tensile Strength: FGE 38-17 exhibits a minimum tensile strength of 580 MPa, ensuring excellent resistance to external forces. This high strength allows it to withstand heavy loads and extreme pressures without deformation or failure.

– Yield Strength: The yield strength of FGE 38-17 is at least 460 MPa. This property indicates the maximum stress the material can withstand without permanent deformation or fracture. The high yield strength of FGE 38-17 ensures structural integrity even under severe conditions.

– Elongation: FGE 38-17 demonstrates an elongation of at least 17%. This property contributes to its ductility, allowing for the absorption of energy and preventing sudden brittle failure. The elongation also enables FGE 38-17 to adapt to dynamic loads and vibrations.

– Impact Toughness: The steel grade exhibits excellent impact toughness, with Charpy V-notch (CVN) values exceeding 40 Joules at -40°C. This exceptional toughness ensures resistance to sudden shocks and ability to withstand dynamic loading.

Chemical Composition:

– Carbon (C): FGE 38-17 contains a carbon content of 0.30-0.40%. Carbon enhances the strength and hardness of the steel, providing excellent resistance to wear and abrasion.

– Silicon (Si): The silicon content in FGE 38-17 is limited to 0.15-0.35%. Silicon improves the steel’s strength and toughness while preventing the formation of undesirable impurities.

– Manganese (Mn): FGE 38-17 includes manganese in the range of 0.60-0.90%. Manganese contributes to the steel’s strength and hardenability, promoting the formation of fine-grained structures and improving its mechanical properties.

– Phosphorus (P) and Sulfur (S): The maximum permissible content of phosphorus and sulfur in FGE 38-17 is 0.030% each. These elements are limited to maintain the steel’s cleanliness and prevent the formation of detrimental impurities.

– Other Elements: FGE 38-17 may contain small amounts of other alloying elements like chromium, nickel, and molybdenum, which further enhance its mechanical properties and resistance to corrosion and fatigue.

Overall, FGE 38-17 steel grade provides an ideal solution for high-stress applications, offering superior mechanical properties and a well-balanced chemical composition that ensures excellent performance and durability in demanding environments.
