Abstract
High strength steel parts 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 or at least about 90,000 psi and warm forming the blank to provide the part of desired geometric configuration while substantially maintaining or increasing the strength properties of the blank.
