Custom 465 is a martensitic, premium-melted stainless steel alloy with a high concentration of nickel and chromium. It is known to have improved tensile strength and fracture toughness, which makes it an excellent choice for aerospace components that require these properties.
Alloy 465 is age-hardenable and has improved fabricability when compared to other alloys in this category. On top of that, it has excellent resistance to stress corrosion cracking. If needed, it can achieve exceptional strength, toughness and stress corrosion cracking by aging it at a higher temperature for longer, or to the H1000 condition (more on that in the Heat Treatment section).
Thanks to that, apart from its widespread use in the aerospace industry, it also finds use in the medical industry, marine equipment, firearms, hand tools, and oil and gas drilling machines. Custom 465 is mostly used for drivers, distractors, drill bits, and shafts.
