Latest Patents

Saini’s listed patent is “Method for Producing Spheroidized or Non-Lamellar Microstructure Steels.” It describes a process for making high-strength hot-rolled steel from a slab containing specified proportions of carbon, manganese, silicon, niobium, sulphur, phosphorus, and nitrogen, with iron as the balance and optional incidental elements.

The method involves heating and hot rolling the steel, followed by cooling and coiling. The steel is then retained at ambient temperature to produce a microstructure containing 75–95% spheroid and 5–25% pearlite. The disclosed approach aims to achieve high strength through control of the steel’s composition and processing conditions.
