General Characteristics
316/4436 is a 316L/4432 alternative with higher carbon content and similar corrosion resistance. 316/4436 is an austenitic stainless steel that belongs to the standard CrNiMo stainless steel family. 316/4436 has the variant with increased molybdenum content for slightly improved corrosion resistance.
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.
316/4436 is available in many product forms and dimensions. It can be supplied with a wide range of functional and aesthetic surface finishes.
Typical Applications
Pulp and paper industry equipment
Pharmaceutical industry equipment
Flanges and valves
