Definitions
- the present invention also provides a method of making high-strength steel structural members including hot forging, rolling or otherwise forming high-strength steel material whereby the mechanical properties of tensile strength and yield strength of the member are substantially the same as or greater than the material used to form the member and wherein the member, with the desired mechanical properties of tensile strength and yield strength, is produced without further strengthening processing steps.
- the flange is integrally formed either continuously or discontinuously with respect to the remainder of the structural member.
- discontinuous flanges are the upper and lower portions of an I-shaped beam with respect to the center portion or of either leg of an L-shaped truss with respect to the other leg of the truss.
- An example of a continuous flange is any chord or portion of the cross-sectional configuration of an O-shaped structural member.
- structural members having at least one flange are O, L, C, Z, I, T, U, V, and W shaped members.
- the method of the present invention for making a high-strength steel structural member includes providing high-strength steel material having a tensile strength of at least about 120,000 psi, and preferably at least about 150,000 psi, and a yield strength of at least about 90,000 psi, and preferably at least about 130,000 psi.
- the high- strength steel material utilized has been hot reduced and cold drawn to provide a billet or blank having the mechanical properties of tensile strength and yield strength stated above.
- the high strength material used for the formation of the structural member in one form may be processed in molten, softened or hardened form and in another form may be a billet or blank to be hot rolled according to this invention.
- the high-strength steel material may be exemplified by the following composition, by weight percent: carbon about 0.30 to about 0.65% manganese about 0.30 to about 2.5% at least 1 ferrous grain refiner from the group consisting of aluminum, niobium, titanium and vanadium, and mixtures thereof, in an effective amount for grain refining up to about 0.35% iron balance.
- the high-strength steel material has the following composition, by weight percent: carbon about 0.40 to about 0.55% manganese about 0.30 to about 2.5% at least 1 ferrous grain refiner from the group consisting of aluminum, niobium, titanium and vanadium, and mixtures thereof, in an effective amount for grain refining up to about 0.20% iron balance.
- compositions listed and claimed herein may include other elements which do not impact upon the practice of this invention.
