Abstract:
High strength steel structural members and a method of making same are disclosed by providing high-strength steel material having a specific chemical composition and preferably a tensile strength of at least about 120,000 psi and a yield strength of at least about 90,000 psi and hot rolling the steel material to provide the structural member of desired geometric configuration.
Abstract:
A method of making high-strength steel structural members is disclosed by providing a blank of high-strength steel having a ferrite-pearlite microstructure and high-strength mechanical properties and cold forming the blank by rolling, upsetting, forging, or extrusion to provide a structural member having a desired geometric cross-section while the mechanical strength of the structural member remains substantially the same or greater than the blank.
Abstract:
Sway bars made of high strength steel having grains with a preferred orientation, and methods of making such sway bars from blanks of high strength steel typically having a yield strength of at least about 90,000 psi and a tensile strength of at least about 120,000 psi.
Abstract:
High strength steel structural members and method of making are disclosed by providing a blank of high-strength steel material having a tensile strength of at least about 120,000 psi and a yield strength of at least about 90,000 psi and warm forming the blank to provide the member of desired geometric configuration while substantially maintaining or increasing the strength properties of the blank.
Abstract:
Hot-rolled high-strength steel elongated structural members and method of making same are disclosed by hot-rolling high-strength steel having a specific chemical composition to provide the members of desired geometrical configuration including a thin web with opposed thicker flanges extending therefrom to increase the load bearing capacity of the members.
Abstract:
Hot-rolled high-strength steel elongated structural members and method of making same are disclosed by hot-rolling high-strength steel having a specific chemical composition to provide structural units. The units are then welded together to provide structural members of desired geometrical configuration including a thin web with opposed thicker flanges extending therefrom to increase the load bearing capacity of the members.
