The grate of the steamer is a part for placing food, usually made of stainless steel or other high-temperature resistant and non-deformable materials. Although there are many kinds of stainless steel, 304 stainless steel is a commonly used material, which is very suitable for making kitchen utensils because of its good corrosion resistance, strength and processability.

However, it is not necessary to use 304 stainless steel for the grate of the steamer, because it depends on the choice and standard of the manufacturer. The grate of the steamer needs to bear the impact of high-temperature steam, and it needs to have certain strength and stability to ensure that the food will not slip and deform. Therefore, some manufacturers may choose other stainless steel materials or other materials to make the grate of the steamer to meet the requirements of the products.

When buying a steamer, consumers can check the product description or consult the sales staff to understand the materials and quality standards used in the steamer grate, so as to choose the products that suit them.
