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.

Working with CRAs in the subsea, offshore, and onshore industries

FMC Technologies and Technip came together in January 2017 to form TechnipFMC, a company dedicated to improving the performance of the world’s energy industry. A global leader in oil and gas projects, technologies, systems, and services, TechnipFMC is divided into three business segments: subsea, onshore/ offshore, and surface. The company employs more than 40,000 people across 48 countries.

NovaCast specifies cast steel alloy

Cast Steel has become an increasingly important part of NovaCast’s business over recent years. The company can cast a very wide variety of both carbon and stainless steels, the bulk of its castings are in the most popular grades.

Perfecting the purity of nickel products

It has long been known that the parts per million range quantity of trace elements has a tremendous influence on the properties of otherwise pure metals (AE van Arkel, Reine Metalle, Berlin 1939) which is also true for nickel. The norm for the purest nickel grade – Ni 270 – was established decades ago for vacuum tube parts.

Heat treatment is crucial for stainless steels due to several reasons. Firstly, it allows for the customization of the material’s mechanical properties. By subjecting the stainless steel to controlled heating and cooling processes, it is possible to achieve specific hardness, strength, toughness, and ductility levels tailored to the intended application. This enables the material to meet the required performance criteria, ensuring it can withstand various mechanical stresses and loads.

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.
