Super Duplex Stainless Steels are magnetic and offer significantly enhanced corrosion resistance.
Super Duplex Stainless Steel Overview
Super Duplex stainless steels are magnetic and provide significantly enhanced corrosion resistance compared to more commonly used grades like 302 and 316. Super Duplex, which merges the properties of both austenitic and ferritic stainless steels, is particularly noted for its superior corrosion resistance and exceptional strength.
