Maraging Steel Plate
What is Maraging Steel Plate?
Maraging steel sheet is a high-strength material sheet known for its toughness, weldability, and crack-resistant properties. It is made up of iron, nickel, cobalt, molybdenum, and low carbon. Parag Metal supplies high-quality maraging steel sheets to a wide range of industries. As a leading supplier of maraging steel sheets, we provide sheets that are strong, durable, and suitable for high-stress applications. These sheets are also corrosion resistant and can be heat treated to increase strength.
Our maraging steel sheets are available in the size 20mm x 1200 x 500. We also offer specialized sheets like shim sheets, perforated sheets, and B.Q. profiles. Finishes include cold rolled (CR), 2B, 2D, BA No(8), satin, and hot rolled (HR). Hardness levels available such as quarter hard, half hard, soft, hard, and spring hard—depending on your need.
