| description | The invention belongs to the field of new materials and relates to novel ultrahigh-strength steel and a preparation method thereof. The preparation method is characterized by comprising the following steps of material formation and material preparation (smelting, forging and heat treatment). According to the novel structural material S280 prepared through the preparation method, the tensile strength is equal to or larger than 1900 MPa, and the fracture toughness is larger than 90 MPa. |
