Grade 1.4404

1.4404 – Stainless Steel for Maximum Corrosion Resistance and Purity

1.4404, also known as AISI 316L, is an austenitic stainless steel designed for applications that require high corrosion resistance and low carbon content. Thanks to its outstanding chemical properties and excellent processability, 1.4404 is widely used in the chemical, food, and pharmaceutical industries as well as in marine environments.

Key Properties of 1.4404

Excellent Corrosion Resistance

With a molybdenum content of approx. 2–2.5%, 1.4404 offers exceptional resistance to pitting, crevice corrosion, and general corrosion, especially in chloride-containing or acidic environments.

Low Carbon Content

The reduced carbon content minimizes the risk of intergranular corrosion, especially after welding. This makes the alloy ideal for applications where high purity and long-term durability are required.

Excellent Weldability

1.4404 is perfectly suited for welding and does not require post-weld heat treatment, simplifying fabrication processes.
