Deep Drawing Austenitic Steels

X2CrNiN23-4 – 1.4362 / S32304 / Z3CN23-04Az / 2327 / 03KH23N6

X2CrNiN23-4 – 1.4362 stainless steel belongs to the group of duplex (dual-phase) stainless steels, combining the beneficial properties of both ferritic and austenitic structures. Commonly known as S32304 (Duplex 2304), this grade is developed as an alternative to conventional 304 and 316 stainless steels, offering higher strength and improved corrosion resistance.

The chemical composition of this steel typically includes approximately 22–24% chromium, 3–5% nickel, and small amounts of nitrogen. The high chromium content provides strong corrosion resistance, while nitrogen enhances mechanical strength and structural stability. The relatively lower nickel content also contributes to a cost advantage, making it particularly attractive for large-scale engineering projects.

One of the most important advantages of 1.4362 stainless steel is its high mechanical strength. Compared to conventional austenitic stainless steels, it offers approximately twice the yield strength, allowing the use of thinner sections while maintaining the same load-bearing capacity. This results in significant benefits in terms of weight reduction and cost efficiency.

In terms of corrosion resistance, this grade provides excellent resistance to stress corrosion cracking, especially in humid and moderately aggressive environments. It performs reliably in many chemical conditions; however, for highly aggressive chloride environments, more highly alloyed duplex grades may be preferred.

X2CrNiN23-4 steel is suitable for both hot and cold forming processes. It offers good weldability, although proper welding procedures must be followed to maintain the duplex microstructure balance.

Overall, 1.4362 (Duplex 2304) stainless steel is a modern engineering material that combines high strength, good corrosion resistance, and economic efficiency, making it a strong alternative for a wide range of industrial applications.
