1 and 304 stainless steel have good corrosion resistance and high temperature resistance, and are suitable for storing and heating food and water. The inner layer is made of 304 stainless steel, which can ensure the safety and hygiene of food and water.

2. Compared with 304 stainless steel, 430 stainless steel has better wear resistance and heat resistance. 430 stainless steel outer layer can increase the durability and beauty of the kettle.

3. The combined design of the inner and outer layers with different materials can effectively isolate the high-temperature heat inside, reduce the temperature of the outer pot, provide better insulation effect and avoid scalding.
