Stainless Steel - Grade 434/1.4113
Description
Stainless Steel Grade 434/1.4113 is a ferritic stainless steel known for its good corrosion resistance and fabricability. It is primarily used in applications that require moderate corrosion resistance and good mechanical properties. The addition of molybdenum enhances its resistance to corrosion, particularly against deicing chemicals.
