Heat treatment of stainless steels

Heat treatment is important for stainless steels as it enables the adjustment of their mechanical properties, such as hardness, strength, and ductility. It also enhances their corrosion resistance and relieves internal stresses, resulting in improved performance and suitability for various applications.

How heat treatment for stainless steels works

Heat treatment of stainless steels typically involves three main steps: heating, holding at a specific temperature, and cooling. The material is heated to a precise temperature to induce desired transformations in its microstructure. It is then held at that temperature for a specific duration to allow for the desired changes to occur. Finally, the material is cooled at a controlled rate, which determines the final properties of the stainless steel.

New opportunities for CENTRAVIS

Stainless Steel World Publisher - December 14, 2015

For years, the majority of car producers used welded or carbon tubes. But standards have risen. Now, the most innovative companies want more efficient and eco-friendly solutions, such as seamless stainless tubes, which is the core competence for Centravis. The welded tubes are good as long as the working pressure doesn’t exceed 300 bars.

Secondly, heat treatment of stainless steels plays a vital role in enhancing the corrosion resistance of stainless steels. Certain heat treatment methods, such as solution treatment and aging, can refine the microstructure and promote the formation of corrosion-resistant phases, reducing the susceptibility to rust and other forms of degradation.

Heat treatment for stainless steels is essential for relieving internal stresses that may have been induced during manufacturing processes like welding or cold working. This stress relief minimizes the risk of cracking, distortion, or premature failure of the stainless steel components.

Heat treatment is a key process to optimize the mechanical properties, corrosion resistance, and structural integrity of stainless steels, ensuring their suitability for a wide range of applications in industries such as aerospace, automotive, construction, and manufacturing.
