Research on High-Temperature Oxidation Resistance of Stainless Steel Plates in New Energy Equipment

Introduction

Stainless steel plates are critical materials in the manufacturing of new energy equipment, where extreme operational conditions demand superior performance. This study focuses on the high-temperature oxidation resistance of stainless steel plates, a key factor ensuring the longevity, safety, and efficiency of components in sectors such as solar thermal power, hydrogen energy, and advanced nuclear systems. The stainless steel research outlined here provides vital insights for material selection and engineering design.

Detailed Analysis

1. Application in New Energy Equipment: Stainless steel plates for new energy equipment are extensively used in heat exchangers, reactor vessels, and high-temperature piping. Their inherent strength and corrosion resistance make them ideal for environments exposed to aggressive media and thermal cycles.

2. Challenges of High-Temperature Oxidation: At elevated temperatures, stainless steel can undergo oxidation, leading to scale formation, thinning, and eventual failure. This stainless steel plate high-temperature oxidation behavior directly impacts equipment service life and maintenance costs.

3. Key Research Findings: Current stainless steel plate research investigates how alloying elements (like chromium, nickel, and aluminum), surface treatments, and microstructural control enhance oxidation resistance. Studies show that increasing chromium content significantly improves the formation of a stable, protective oxide layer (Cr₂O₃), which acts as a barrier against further oxygen diffusion.

4. Performance Optimization: Research also focuses on developing specialized grades and coatings tailored for specific new energy applications. Techniques such as pre-oxidation treatment and the application of thermal spray coatings are proven to substantially boost the high-temperature antioxidant performance of stainless steel plates.

Conclusion

In conclusion, advancing the high-temperature oxidation resistance of stainless steel plates is fundamental to the progress of reliable and efficient new energy technologies. Continuous stainless steel plate research enables the development of optimized materials that withstand severe operational demands. By integrating these findings, manufacturers can enhance the durability and performance of new energy equipment stainless steel plates, supporting the global transition towards sustainable energy solutions.
