EN Series Plates

EN Series Low Alloy Steel Plates are high-performance materials characterized by a low carbon content (typically below 0.20%), ensuring exceptional weldability and superior hardening capabilities. Jitu Milan Steels provides premium-grade EN8 (C45) Plates, manufactured using high-purity raw materials selected in strict accordance with international standards. Our production process leverages modernized machinery and refined technology to ensure every plate meets precise industrial requirements.

These plates are widely recognized for their high yield and tensile strength, making them versatile enough for various heavy-duty applications. A key feature of our EN series is its outstanding hardenability, which is achieved through careful control of the grain size during manufacturing. Additionally, these plates offer excellent durability and corrosion resistance, even in welded conditions, ensuring that mechanical properties remain stable throughout the lifespan of the project.

We deal in all sizes is from 1.6MM to 300MM as per client's requirements.
