Manufacturing method of hot rolled steel and hot rolled steel

The present invention discloses a method for manufacturing a hot-rolled steel and hot-rolled steel, for producing a high strength and toughness hot rolled steel save resources, reduce production costs. The method comprising: melting a raw material liquid steel, wherein the molten steel contains by weight 0.20 to 0.30 molybdenum accounts; after refining the molten steel, the molten steel is cast into a cast slab; the slab to a hot rolling rigid rolling; heat treating the hot-rolled steel.
