| description | The invention discloses steel for thick 900 MPa-grade high-surface engineering machinery and a preparation method of the steel, and belongs to the technical field of metallurgical technologies. The thickness of the steel for the engineering machinery is 20-25mm, the tensile strength is 900MPa, and the thickness of oxide scale on the surface of the steel for the engineering machinery is 15-19 microns. The steel for the engineering machinery is obtained by sequentially carrying out smelting, rough descaling, rough rolling, intermediate billet cooling, finish rolling, finish descaling, first-section cooling, second-section cooling, coiling, steel coil transverse cutting and steel plate quenching and tempering heat treatment according to the component proportion. The steel for the engineering machinery has the advantages that the thickness is 20-25mm, the tensile strength is 900MPa, and the thickness of oxide scale on the surface of the steel for the engineering machinery is 15-19 microns.
