METHODS FOR PREPARING HIGH PERFORMANCE PRESS-HARDENED STEEL COMPONENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240052445 titled 'METHODS FOR PREPARING HIGH PERFORMANCE PRESS-HARDENED STEEL COMPONENTS
Simplified Explanation
- Method for preparing a press-hardened steel component - Involves heating a steel alloy blank to two different temperatures in different zones of a furnace - First zone has a lower flow rate of protective gas, while the second zone has a higher flow rate - Involves stamping and quenching the heated blank at a constant rate to form the press-hardened steel component
Potential Applications
- Automotive industry for manufacturing lightweight and strong components - Aerospace industry for producing high-strength parts
Problems Solved
- Provides a method for efficiently producing press-hardened steel components - Allows for precise control over the heating and cooling process
Benefits
- Improved strength and durability of steel components - Cost-effective manufacturing process - Consistent quality and performance of the final products
Original Abstract Submitted
a method for preparing a press-hardened steel component is provided. the method includes forming a heated blank by heating a steel alloy blank to a first temperature in a first zone of a furnace having two or more zones, and after the heating of the steel alloy blank to the first temperature, heating the steel alloy blank to a second temperature in a second zone of the furnace. the second temperature is greater than the first temperature. the first zone has a first flow rate for a protective gas, and the second zone has a second flow rate for the protective gas that is greater than the first flow rate. the method further includes stamping and quenching the heated blank at a constant rate to a temperature between a martensite finish temperature of the steel alloy defining the steel alloy blank and room temperature to form the press-hardened steel component.
