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.
