Deep Drawing Austenitic Steels
X2CrNi18-9 – 1.4307 / SUS304L / Z2CN18 / 304S11 / 2352 / 04KH18N10
X2CrNi18-9 – 1.4307 stainless steel belongs to the group of austenitic stainless steels and is widely used in applications requiring high corrosion resistance and excellent workability. It is generally considered a variant of the 304L series, offering similar characteristics to 1.4301 (AISI 304) but with a lower carbon content, making it more suitable for welded applications.
This steel typically contains approximately 17–19% chromium and 8–10% nickel. This composition provides strong resistance to corrosion while also delivering a bright and aesthetically appealing surface finish. Due to its low carbon content, the risk of intergranular corrosion after welding is significantly reduced, making it a reliable choice for welded constructions.
X2CrNi18-9 steel is suitable for both hot and cold forming processes. It performs consistently in operations such as bending, cutting, deep drawing, and welding. Its high ductility allows easy shaping and provides good resistance to impact, ensuring flexibility and efficiency in manufacturing processes.
In terms of corrosion resistance, this grade performs well in humid environments, mild chemical conditions, and general outdoor applications. However, in high chloride or highly aggressive environments, more highly alloyed grades such as 316L are recommended.
Thanks to its hygienic properties, this steel is widely used in the food, beverage, and medical industries. Its smooth and easy-to-clean surface helps prevent bacterial growth and supports high hygiene standards. Additionally, its modern and decorative appearance makes it suitable for architectural and aesthetic applications.
Overall, X2CrNi18-9 – 1.4307 stainless steel is a reliable and versatile engineering material, offering an excellent balance of durability, workability, and cost-effectiveness across a wide range of applications.
