Duplex Steel Sheet
Duplex Steel Sheet Supplier
Pearl Steel Industry stands out as a reliable Duplex Stainless Steel Sheet supplier and stockist, particularly catering to industries that require materials with excellent strength and resistance to corrosion. Our extensive range of Duplex Steel Sheets is highly sought after in sectors like chemical processing, petrochemical, and marine applications. These industries benefit from the unique combination of austenitic and ferritic structures in Duplex Stainless Steel, which enhances its performance compared to standard stainless steel. We specialize in premium grades such as Duplex UNS S31803 Sheets and Duplex UNS S32205 Sheets, both known for their outstanding resistance to harsh environments and long-term durability.
The Duplex Stainless Steel Sheet is composed of 22-25% chromium, 4-6% nickel, 2-3% molybdenum, and trace amounts of nitrogen, which provides superior resistance to pitting, crevice corrosion, and stress corrosion cracking. Our Duplex Steel Sheets meet international standards, including ASTM A240 and ASME SA240, ensuring that the product adheres to the highest quality requirements for even the most demanding applications. Additionally, the DIN 1.4462 specification is widely recognized for European projects, making it a popular choice for international customers.
Manufacturing Process of Duplex Stainless Steel Sheets
The process of manufacturing Duplex Stainless Steel Sheets involves several important steps to ensure a high-quality final product:
- Reheating Furnace: The steel stock is heated to the required rolling temperature in a reheating furnace.
- Scale Breaker: The slab then passes through a scale breaker, where high-pressure water jets remove furnace scale.
- Finish Rolling: Cold rolling is employed to reduce the thickness and achieve the desired surface finish.
- Cooling/Quenching: The steel is rapidly cooled to retain the mechanical and corrosion-resistant properties.
- Skin Pass Mill: This process enhances the surface finish and ensures the desired mechanical strip properties.
- Marking & Packing: Finally, proper marking and packaging ensure the sheets are safely handled and delivered.
