With the rapid development of offshore oil and gas extraction, desalination plants, chemical processing, and marine engineering, the demand for EN 1.4410 super duplex stainless steel bars has increased significantly. These industries require materials with exceptional strength, corrosion resistance, and long service life, which has directly driven up the market price per kilogram of super duplex stainless steel.
Understanding the price per kilogram of EN 1.4410 stainless steel bars, the factors influencing the price, and how to procure them efficiently can help buyers control project costs while ensuring the long-term performance of their equipment.
🔹What Is EN 1.4410 Super Duplex Stainless Steel bar?
1.4410 (UNS S32750/F53) super duplex stainless steel bar is a high-performance corrosion-resistant alloy with a 50/50 ferrite-austenite microstructure. It contains approximately 25% chromium, 4% molybdenum, and 7% nickel. It possesses excellent yield strength (≥ 530 N/mm²) and superior resistance to chloride pitting, crevice corrosion, and stress corrosion cracking, making it ideal for harsh environments with high chloride content, such as marine, oil and gas, and chemical industries.

Why is EN 1.4410 more expensive than duplex 2205?
EN 1.4410 (super duplex stainless steel, such as 25Cr) is more expensive than 1.4462 (standard duplex stainless steel, such as 22Cr) primarily due to its higher alloy element content (approximately 25% Cr, 4% Mo, 7% Ni) and superior corrosion resistance and strength properties. The significantly increased molybdenum (Mo) and nickel (Ni) content provides better resistance to pitting and stress corrosion, which directly drives up the raw material cost.
