Product Description:
Custom 465 is a high-strength, precipitation-hardenable martensitic stainless steel alloy that is designed for applications requiring excellent strength, hardness, and corrosion resistance. It combines high strength with good toughness and can be hardened to an extremely high level using heat treatment, making it ideal for demanding industrial, aerospace, and automotive applications.
Features:
- High Strength: Custom 465 can achieve extremely high tensile and yield strengths, making it ideal for heavy-duty applications in which mechanical properties like strength and toughness are critical.
- High Toughness: Despite its strength, Custom 465 maintains good toughness, which is essential for parts that are subjected to dynamic stresses.
- Wear Resistance: The material provides good wear resistance, making it suitable for parts subjected to wear and friction.
- Magnetic Properties: As a martensitic stainless steel, Custom 465 is magnetic, which may be advantageous in certain applications that require magnetic properties.
- Heat Treatable: It is designed to be heat-treated to achieve a variety of mechanical properties, allowing for precise control over strength, hardness, and other characteristics.
