Custom 465 is a martensitic stainless steel alloy that meets the AMS 5936 and BMS 7-364 specifications. Some key features that make this alloy a good choice in certain applications include:

1. High Strength: Custom 465 has a high tensile strength, typically in the range of 200-250 ksi (1380-1725 MPa), making it well-suited for high-stress components.
2. Corrosion Resistance: The alloy exhibits good corrosion resistance, better than many other martensitic stainless steels, due to its composition which includes chromium, nickel, and molybdenum.
3. Heat Treatability: Custom 465 can be heat treated to achieve a wide range of mechanical properties, from high strength to good ductility, depending on the specific application requirements.
4. Wear Resistance: The martensitic microstructure of Custom 465 gives it good wear resistance, making it suitable for components that experience sliding or abrasive wear.
5. Magnetic Properties: Unlike many austenitic stainless steels, Custom 465 is ferromagnetic, which can be advantageous in certain applications.
6. Compatibility with AMS 5936 and BMS 7-364: Meeting these aerospace and defense industry specifications ensures the alloy’s quality, consistency, and suitability for use in critical applications within these sectors.

In summary, the combination of high strength, corrosion resistance, heat treatability, wear resistance, and magnetic properties, along with its compliance with relevant industry standards, makes Custom 465 stainless steel a good choice for various engineering and aerospace applications where these characteristics are required.
