Heat treating is a valuable technique that can be used in various parts of the manufacturing process to improve the native characteristics of a metal component. By heating a metal or alloy to a specific temperature and allowing it to cool, manufacturers can impart additional properties, such as resistance to wear and tear. There are many different types of heat treating, including hardening, annealing, case hardening, normalizing, and tempering. Each of these processes results in various desirable properties that make heat treatments critical for a wide range of industries, including the medical industry.

Importance of Heat Treatment for the Medical Industry

Medical device heat treating is a critical process for equipment used in applications requiring biocompatibility, high mechanical strength, and long-term corrosion resistance. Heat treating helps establish the required fit, form, and function for a medical device while ensuring conformance to the medical industry’s strict standards for reliability. Metals including titanium, cobalt-chromium, stainless steel, and other alloys are commonly used for medical manufacturing. Cobalt chromium, which is commonly used for medical implants, requires heat treatment to strengthen the device and ensure it lasts a lifetime.

Stainless steel is another popular metal in the medical field that offers many advantages over other choices. It provides enhanced corrosion resistance, ductility, and is strong enough to withstand near-constant cleaning and sterilization. It is critical to choose a manufacturer that understands how to impart and safeguard these key mechanical properties. A mistake can lead to a defective tool that can negatively impact the results of a procedure.

Heat treating is critical for various medical devices such as implants, surgical tools, and more, to ensure optimal mechanical properties.

Common Medical Applications That Undergo Heat Treatment

Heat treating is a vital and necessary process for devices used within the medical industry, such as medical implants, dental tools and appliances, and surgical tools. Medical device heat treating results in aesthetically pleasing tools and devices with minimal distortion and precise final mechanical properties. Applications include:

  • Battery contacts
  • Bone saws
  • Bone screws
  • Capacitor cans
  • Cases
  • Clamps
  • Clips
  • Hip implants
