Aisha Nickel Alloys, located in Muscat, Oman, stands out as a leading manufacturer and supplier of top-notch Duplex Steel Sheets and Plates. Known for their meticulous engineering and strict quality control, this company caters to a variety of industries that demand exceptional corrosion resistance and mechanical strength. Their Duplex Steel Sheets and Plates cleverly blend the advantages of both austenitic and ferritic stainless steels, delivering remarkable durability, resistance to stress corrosion cracking, and impressive toughness even in the toughest conditions. Aisha Nickel Alloys guarantees that every product adheres to international standards, making them a reliable partner for clients in sectors like oil & gas, chemical processing, marine, and infrastructure.
Typically, Duplex Steel Sheets and Plates are made from a well-balanced mix of around 22% chromium, 5% nickel, 3% molybdenum, and a touch of nitrogen, which boosts their corrosion resistance. This unique composition creates a dual-phase microstructure of ferrite and austenite, resulting in outstanding mechanical properties such as high tensile strength, excellent yield strength, and remarkable toughness. The material is highly resistant to pitting, crevice, and stress corrosion cracking, making it perfect for challenging environments. Additionally, duplex steel maintains its dimensional stability and formability, ensuring dependable performance in both structural and industrial applications.
