Esha Steel, a trustworthy manufacturer and supplier located in Kolkata, is proud to present top-notch Maxil 690 sheets and plates which are widely recognized for their outstanding strength and long-lasting feature. As part of its commitment to provide steel solutions that really perform, Esha Steel makes sure that each Maxil 690 unit conforms to international quality standards in terms of hardness, weldability, and resistance. These ultra-high-strength structural plates are designed to be used in heavy-duty areas of construction, machinery, and industrial applications.
Besides, Esha Steel is able to assure excellent surface finish and dimensional accuracy through the employment of advanced processing methods combined with rigorous quality control. Their resolve to customer convenience is the main reason why they are the most reliable brand when it comes to the high-strength steel sector in different industries.
Maxil 690 sheets and plates are made from a purified alloy composition that generally includes carbon, manganese, silicon, and micro-alloying elements such as niobium, vanadium, and titanium. The mixture raises the strength level while the good formability and weldability are kept intact. The material provides a minimum yield strength of about 690 MPa and a very high tensile strength which is excellent for heavy metal constructions. Maxil 690 also has extraordinarily good impact resistance at even low temperatures, thus it is very tough and durable. The material’s mechanical properties position it as the most suitable ones for the heavy load structural application and long-term usage.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Maxil 690 sheets and plates are at the core of applications that need extreme strength, lastingness, and structural stability. They are perfect for the creation of heavy-duty machines, cranes, earthmoving machinery, and lifting devices that require a high level of load-bearing capacity. Thus, heavy industries rely on the material to produce robust machines that take on heavy tasks safely and efficiently.
With the growing need for safer and more durable methods to support and mobilize our modern societies, these materials have become standard components in giants of construction and infrastructure such as bridges, skyscrapers, industrial platforms, and cranes. Moreover, the material’s spectral range of application extends to the production of mining equipment, transport vehicles, truck bodies, and pressure-bearing components that require high levels of strength and resistance.
By the inherent properties of the material such as a good-to-excellent resistance to impact and a perfect weldability, Maxil 690 has become a go-to metal for the production of parts that must deliver their performances reliably and constantly in the hard-conditioned areas, hence, being a versatile one for the demanding engineering applications sector.
