METHODS OF FORMING STEEL SHEETS WITH ENHANCED FLATNESS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17873926 titled 'METHODS OF FORMING STEEL SHEETS WITH ENHANCED FLATNESS
Simplified Explanation
- The patent application describes a method for preparing a steel alloy sheet to improve its flatness. - The method involves heating a steel alloy material to a specific temperature, holding it at that temperature for a certain period of time, and then air quenching and cooling it. - The steel alloy material used in the method contains chromium in a specific range of 0.5 wt. % to 6 wt. %. - The purpose of the method is to enhance the flatness of the steel alloy sheet, which can be beneficial in various applications. - The method provides a specific temperature range and holding time to achieve the desired flatness enhancement. - The use of air quenching and cooling helps in the preparation of the steel alloy sheet. - The presence of chromium in the steel alloy material is important for the effectiveness of the method.
Original Abstract Submitted
The present disclosure provides a method for preparing a steel alloy sheet to enhance flatness. The method includes, inter alia, heating a steel alloy material to a first temperature that is greater than a full-austenitization point for the steel alloy material; holding steel alloy material at the first temperature for a period greater than or equal to about 1 second to less than or equal to about 10,000 seconds to from a precursor steel sheet; air quenching the precursor steel sheet to a second temperature that is less than the first temperature and greater than martensitic transformation starting temperature for the steel alloy material; and cooling the precursor steel sheet to room temperature to prepare the steel alloy sheet. The steel alloy material includes greater than or equal to about 0.5 wt. % to less than or equal to about 6 wt. % of chromium.
