ASTM 316L - EN 1.4432

Essential details
316L/4432 has high resistance to non-oxidizing acids and chloride-containing media due to its higher molybdenum content. 316L/4432 has good formability and weldability.

316L/4432 is an austenitic stainless steel that belongs to the standard CrNiMo stainless steel family. It has low carbon content for improved resistance against intergranular corrosion after welding 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.

Typical Applications:

- Drinking water systems

- Cooling systems

- Wastewater systems

- Flanges and valves
