EN 1.4662 / UNS S44660 Stainless Steel Sheet
Top EN 1.4662 / UNS S44660 Stainless Steel Sheet Manufacturer in China
EN 1.4662 / UNS S44660 is a premier super-ferritic stainless steel specifically engineered to thrive in aggressive, corrosive environments where conventional steels falter. Its formulation, significantly enriched with chromium and molybdenum, provides exceptional resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking (SCC). The ferritic structure of this alloy imparts a unique combination of beneficial properties. These characteristics make EN 1.4662 / UNS S44660 a cost-effective and high-performance solution for a wide range of applications, including condenser and feedwater heater tubing, desalination systems, and heat exchangers in the chemical, petrochemical, and power generation industries.

Characteristics of EN 1.4662 / UNS S44660 Stainless Steel
- Exceptional Chloride Corrosion Resistance: Outperforms standard grades with high Cr/Mo for superior seawater/chloride resistance.
- Excellent Thermal Properties: The alloy exhibits higher thermal conductivity and a lower coefficient of thermal expansion compared to austenitic stainless steels.
- High Mechanical Strength and Stiffness: The ferritic structure provides high inherent strength and a high modulus of elasticity.
- Good Weldability: Stabilized with Ti/Nb to prevent weld zone corrosion, maintaining post-fabrication integrity.
- Cost-Effective and Nickel-Free: Nickel-free EN 1.4662 provides cost stability compared to high-Ni alloys for compatible applications.
- Good Formability and Ductility: High strength with good formability for complex industrial components
- Superior Erosion Resistance: This grade has a higher resistance to erosion from water droplets and steam compared to other materials.
- Resistance to Hydrogen Embrittlement: Self-recovering from hydrogen embrittlement, ensuring reliable performance in critical process environments.
