Essential details
Supra 316L/4435 is a Supra 316L/4432 alternative with higher chromium and nickel content for enhanced corrosion resistance and formability. Supra 316L/4435 is an austenitic stainless steel that belongs to the standard CrNiMo stainless steel family. Supra 316L/4435 has low carbon content for improved resistance against intergranular corrosion after welding, increased nickel content for improved formability, and increased molybdenum content for slightly improved corrosion resistance.

Due to their molybdenum content, the austenitic CrNiMo standard grades can be used in applications with increased demand for corrosion resistance. Their well-balanced material properties make them suitable for the fabrication of many products.

Supra 316L/4435 is available in many product forms and dimensions. It can be supplied with a wide range of functional and aesthetic surface finishes.

Typical Applications:

- Urea plants

- Pulp and synthetic fiber plants

- Flanges and valves
