EN 1.4401, ASTM TYPE 316H / UNS S31609 Stainless Steel

General Characteristics

316/4401 is a normal-carbon alternative to 316/4404 that is widely used for various applications. 316/4401 is an austenitic stainless steel that belongs to the standard CrNiMo stainless steel family and has normal carbon, nickel, and molybdenum content.


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

Mechanical Properties

The mechanical properties of the available products in the soft annealed condition at room temperature are given in the table below. Moderate strengths can be reached at elevated temperatures (~550 °C/1022 °F). Temperatures for excessive scaling are close to 850 °C/1562 °F. 


This grade, along with other austenitic corrosion-resistant steels, exhibits very high ductility and high elongation to fracture. It is not susceptible to brittle fracture in the solution annealed condition.
