High-Strength Austenitic Steels

X2CrNiMo18-14-3 – 1.4435 / 316L / TP316L / 00Cr17Ni14Mo2 / Z3CND17-12-03 / SUS316L

X2CrNiMo18-14-3 – 1.4435 stainless steel belongs to the group of austenitic stainless steels and is specifically developed for applications requiring high purity, superior corrosion resistance, and strict hygiene standards. It is generally considered a refined and higher-performance version of the 316L family. While it shares many similarities with 1.4404 (standard 316L), its higher nickel content provides improved stability and corrosion resistance in certain aggressive environments.

This steel typically contains approximately 17–18% chromium, 12–15% nickel, and 2.5–3% molybdenum. The addition of molybdenum significantly enhances resistance to pitting and crevice corrosion, especially in chloride-containing environments. Its low carbon content (L grade) minimizes the risk of intergranular corrosion after welding, ensuring long-term reliability in welded structures.

One of the key advantages of 1.4435 stainless steel is its suitability for high-hygiene applications. Its low carbon level and high purity reduce contamination and facilitate easy cleaning. It is particularly preferred in pharmaceutical, biotechnology, and food processing industries. Additionally, its compatibility with surface treatments such as electropolishing provides further benefits in hygienic environments.

From a mechanical standpoint, this grade offers moderate strength combined with high ductility, making it suitable for both hot and cold forming processes. It also provides excellent weldability and can be easily adapted to various manufacturing techniques.

X2CrNiMo18-14-3 – 1.4435 steel delivers reliable performance in aggressive chemical environments and applications requiring high cleanliness standards. It is a preferred material in industries where quality, durability, and hygiene are critical.
