Heat treatment is a process for improving the material properties of various metals used in medical products.
These treatments are designed to enhance qualities such as fatigue resistance, strength, hardness, and, in certain cases, to ensure that the material retains a desired shape. The goal is to optimize the mechanical and physical properties of the metal to meet the demanding requirements of the applications, where reliability and performance are paramount.
GTI Medical specializes in a wide range of heat treatments for medical-grade metals. As part of our comprehensive capabilities and services, GTI offers treatments such as annealing and H900 for materials such as stainless steel (3XX series) and the PH (Precipitation-Hardening) family. These treatments modify the metal’s microstructure, thereby improving its strength, durability, and resistance to stress and fatigue, making it ideal for high-performance medical devices.
Additionally, GTI can design and perform shape-setting heat treatments for Nitinol. Shape setting allows the material to be set in a predetermined shape that is retained at specific temperatures, making it essential for applications that require the device to revert to a particular form after deformation. Part of GTI’s expertise includes the design and manufacturing of custom fixtures and tools to facilitate the shape formation process. These fixtures are essential for ensuring that Nitinol is precisely treated to achieve the desired shape and functionality.
In some cases, GTI offers heat treatments in a vacuum environment, particularly when there is a specific requirement to preserve the material’s properties and prevent oxidation or contamination during heating. GTI has the capability to conduct heat treatments in such a controlled atmosphere to ensure that the materials retain their integrity and meet all necessary specifications.
Once the heat treatment process is complete, GTI provides comprehensive documentation to ensure that the treatment meets the necessary regulatory and validation standards. This can include a temperature-versus-time graph for the heat treatment process. Upon request, GTI can also provide a stress-strain diagram of the material after treatment. This diagram illustrates the mechanical behavior of the material under stress and is an important tool for assessing its suitability for medical applications.
Medical devices must behave reliably over time. Heat treatment ensures appropriate mechanical properties such as tensile stress, hardness, elongation, fatigue resistance, and desired structural characteristics.
