Hassan Sheets and Plate, based in Riyadh, Saudi Arabia, has built a solid reputation as a reliable manufacturer and supplier of high-performance metal products, providing cutting-edge material solutions for essential industrial applications. One of their standout offerings is the **Maraging Steel 250/300/350 Sheets and Plates**, which are ultra-high-strength steels celebrated for their remarkable toughness, impressive yield strength, and minimal distortion during heat treatment. These grades are perfect for sectors like aerospace, defense, tooling, and precision engineering. At Hassan Sheets and Plate, they prioritize precision manufacturing, rigorous quality control, and timely delivery to satisfy the demanding requirements of both local and international clients.
The **Maraging Steel 250/300/350 Sheets and Plates** mainly consist of iron and nickel (18–19%), along with cobalt (8–12%), molybdenum (4–5%), and small amounts of titanium and aluminum. These grades can be heat-treated and show increasing mechanical strength across the series: Maraging 250 (~1,700 MPa), Maraging 300 (~2,000 MPa), and Maraging 350 (~2,400 MPa) in tensile strength. All grades boast excellent ductility, toughness, and minimal distortion during aging, while also offering great machinability and weldability for complex, high-stress applications.
