High-Strength Austenitic Steels
X6CrNiMoTi17-12-2 – 1.4571 / X10CrNiMoTi18-10 / SUS316Ti / Z6CNDT17-12 / H17N13M2T
X6CrNiMoTi17-12-2 – 1.4571 stainless steel belongs to the group of austenitic stainless steels and is specifically developed for applications requiring high temperature resistance and enhanced corrosion resistance. Commonly known as 316Ti, this grade is a titanium-stabilized version of the 316 series, offering improved performance in both thermal and chemically aggressive environments.
This steel typically contains approximately 16–18% chromium, 10–13% nickel, and 2–2.5% molybdenum. The addition of molybdenum significantly improves resistance to pitting and crevice corrosion, especially in chloride-containing environments. The presence of titanium stabilizes the material by binding with carbon, preventing the formation of chromium carbides and thereby reducing the risk of intergranular corrosion at elevated temperatures. This makes it particularly suitable for welded structures exposed to heat.
One of the most important features of 1.4571 stainless steel is its ability to maintain structural stability at elevated temperatures. It can perform reliably within a temperature range of approximately 400°C to 800°C, making it ideal for long-term use in energy, chemical, and process industries.
From a mechanical perspective, this grade offers moderate strength combined with high ductility, allowing it to be used in both hot and cold forming operations. It also provides excellent weldability, and in most cases, post-weld heat treatment is not required, which simplifies manufacturing processes.
In addition to its technical advantages, 1.4571 stainless steel features a smooth and bright surface finish, making it suitable for both hygienic and decorative applications. As a result, it is used not only in industrial environments but also in architectural and design projects.
Overall, X6CrNiMoTi17-12-2 – 1.4571 (316Ti) stainless steel stands out as a high-performance engineering material, offering superior corrosion resistance, high-temperature stability, and long service life in demanding conditions.
