One of the top producers and suppliers of superior Maraging Steel Sheets and Plates is Kunj Sheets and Plates, situated in Chennai, India. Our speciality is maraging steels, which are renowned for their exceptional toughness, dimensional stability, and ultra-high strength. We are renowned for providing high-performance materials. Modern technology is used in the production of our sheets and plates, which come in a range of grades and sizes to accommodate demanding applications. Kunj Sheets and Plates provides dependable solutions for demanding engineering environments in sectors like nuclear power, tooling, aerospace, and defence under strict quality control and adherence to international standards.
Low-carbon, high-nickel alloys, such as maraging steel sheets and plates, are usually made up of about 18% nickel with cobalt, molybdenum, titanium, and aluminium added. They can be hardened by ageing instead of carbon content because of their special composition. They provide outstanding fracture toughness, fatigue resistance, high yield strength, and tensile strength of up to 2,000 MPa. These steels are very machinable when annealed and show very little distortion when heat treated. They are perfect for tooling and structural applications in harsh environments because of their strength and ductility.

Marraging steel sheets and plates provides many advantages such as exceptional strength, high toughness and excellent hardness. They are resistant to fatigue, shock, and stress making them more susceptible to cracking, making them ideal for aerospace, security, and equipment applications. Marezing steel also has good weldability, formability and dimensional stability at good temperatures. Its ability to retain mechanical properties for extended periods of time, coupled with its relatively low elongation and minimal distortion, makes it a desirable material for high-performance, precision-designed materials requiring machining high quality.
Because of their remarkable strength and durability, maraging steel sheets and plates are utilised in many demanding and high-stress applications. They are used for structural elements, engine parts, and aircraft landing gear in the aerospace sector. They are used by the defence industry in military-grade hardware, rocket motor cases, and missile casings. They are used in the tool and die industries for high-performance dies, moulds, and machine parts. They are also utilised in high-performance motorsport applications and as structural components in nuclear facilities. They are indispensable in extreme environments and precision engineering due to their superior fatigue life and resistance to deformation.
