316/316L/316Ti Stainless Steel Pipe EN 1.4401 1.4404 1.4432 1.4435 1.4571 ASTM A312

316 stainless steel is a normal-carbon alternative to 316L/1.4404 that is widely used for various applications. It is an austenitic stainless steel that belongs to the standard CrNiMo stainless steel family and has normal carbon, nickel, and molybdenum content.

316L/1.4404 has low carbon content for improved resistance against intergranular corrosion after welding.

316L/1.4432 has high resistance to non-oxidizing acids and chloride-containing media due to its higher molybdenum content, and has low carbon content for improved resistance against intergranular corrosion after welding.

316L/1.4435 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.

316Ti is a titanium-stabilized alternative to 316L/1.4404. With its titanium content, it has enhanced resistance to welding intergranular corrosion, and can be used at elevated temperatures.
