Bidirectional steel is a kind of steel with two different microstructures, which usually needs heat treatment, including baking, in the manufacturing process to enhance its strength and stability. In the baking process, temperature and time are key factors. Usually, the oven temperature is between 800℃ and 950℃, and the baking time depends on the thickness of the steel plate, which is usually several minutes to dozens of minutes.

However, improper baking treatment may have a negative impact on the microstructure and properties of bidirectional steel. Therefore, before baking, it is necessary to understand the properties of bidirectional steel and the corresponding heat treatment process to ensure that the steel structure and properties will not be damaged during baking.
