Nowadays, for many families, whether they choose an oven, a frying pan or even a multifunctional air oven, they pay more attention to materials. Although stainless steel is corrosion-resistant and heats up quickly, it is easy to deform and yellow at high temperature. The enamel material is resistant to high temperature and has good energy storage, so the temperature will be more uniform. Therefore, if it is an oven, it is recommended to choose enamel liner material. Moreover, the enamel liner can withstand a wide range of temperature changes and can withstand high temperature melting of -60 to 450 degrees. Physically, the enamel liner has the characteristics of compression resistance, tension resistance, elasticity, electrical insulation and no pollution. Chemically, it has the characteristics of acid resistance, alkali resistance, high temperature resistance and water vapor resistance. Its bearing capacity and heat preservation capacity are stronger than that of stainless steel liner, and it will not produce harmful substances, so it is a safe and reliable liner material. In addition, when barbecue oil stains, such as long-term use of stainless steel liner, it is easy to turn yellow, affecting appetite. Comparatively speaking, the enamel liner is cleaner, and the oil stain can be removed with a rag.
