Product Description

Product Description

Introduction

Custom 465 is a premium double vacuum melted martensitic Stainless Steel manufactured by Carpenter Technology Corporation. This material is an excellent combination of strength, toughness, and corrosion resistance. It possesses high strength and toughness, has relative ease of fabrication, and provides reliable, long-term service in corrosive environments. The typical strength of this alloy can be as high as 1758 MPa (255 ksi), combined with fracture toughness of about 88-99 MPa-square-root-meter (80-90 ksi-square-root inch) and corrosion resistance approaching that of Type 304 stainless.

Custom 465 stainless can be considered as a corrosion resistant replacement for 300M, AISI 4340, and similar types of steels that must be plated or otherwise surface coated to provide corrosion resistance. This grade features improved tensile strength, fracture toughness and improved fabricability and excellent resistance to stress corrosion cracking.

Processing method

Machinability:
Best machinability is in the overaged H1150M condition, but can also be done in the Solution Annealed condition.

Heat Treatment:
This Material is normally supplied in Condition A (Solution Annealed)
Heat to 1800° F ± 15° F (982° C ± 8° C), then hold at that temperature for 1 hour. Cool rapidly by quenching for parts under 12", or air cool swiftly for parts over 12"

Refrigerate to -100° F (-73° C) and hold for eight hours, followed by warming to room temperature
This should within a 24-hour period

Please note that this process should be done in a 24-hour timeframe after solution annealing

Achieving high strength levels of Custom 465 requires an additional age hardening step by heating to 900 to 1150°, hold 4 to 8 hours, air cool for sizes under 3", quenching for sizes over 3".

Applications

Custom 465 steel is used in the medical field mainly to manufacture high-strength and high-ductility medical devices.
Custom 465 steel is a high-quality, age-hardenable, high-strength martensitic stainless steel with extremely high strength, excellent toughness and corrosion resistance. These characteristics give it significant advantages in the manufacture of medical devices. Specifically, Custom 465 steel is widely used in the manufacture of endoscopes/arthroscopy, plastic surgery, dental and catheter equipment, especially in instruments and equipment that require high strength and high ductility, such as torque screwdrivers, minimally invasive surgical instruments and hand tools, etc. 12. In addition, because the alloy combines strength, toughness and fatigue resistance, it is also increasingly used in medical knives, especially endoscopes/arthroscopy and plastic surgery.
