METHODS FOR PREPARING HIGH PERFORMANCE PRESS-HARDENED STEEL COMPONENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17965312 titled 'METHODS FOR PREPARING HIGH PERFORMANCE PRESS-HARDENED STEEL COMPONENTS
Simplified Explanation
The method involves heating a steel alloy blank in a furnace with multiple zones, first to a lower temperature in the first zone and then to a higher temperature in the second zone.
- Heating a steel alloy blank to a first temperature in the first zone of a furnace.
- Heating the steel alloy blank to a second, higher temperature in the second zone of the furnace.
- 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 producing press-hardened steel components with controlled properties. - Enables the production of complex shapes with high strength-to-weight ratio.
- Benefits:**
- Improved strength and durability of steel components. - Cost-effective manufacturing process for high-performance parts.
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.
