Difference Between Duplex and Super Duplex Stainless Steel
What is the Difference Between Duplex and Super Duplex Stainless Steel? Significant difference between Super Duplex Stainless Steel and Duplex Stainless Steel . Super Duplex variants are characterized by a higher alloying addition of 25% chromium, in contrast to Duplex Stainless Steels with 22% chromium. Elevating the chromium content enhances the resistance to pitting corrosion. It’s important to note that these factors are not the sole determinants; other variables also play a role. Price Difference Between Duplex and Super Duplex Stainless Steel Super duplex materials , owing to their higher chromium, nickel, and molybdenum content, are more expensive compared to the standard duplex grades. Within both standard duplex and super duplex categories, various grades exist, each with its distinct material composition. As a result, the prices differ based on these compositions. Generally, a super duplex is pricier than the standard duplex grades due to its enhanced alloy content and s
