Stainless steel commonly used for tableware on the market is mainly categorized into three grades: 201, 304, and 316. These grades differ significantly in their compositional structure, corrosion resistance, safety of use, and suitable application scenarios.
Stainless steel commonly used for tableware on the market is mainly categorized into three grades: 201, 304, and 316. These grades differ significantly in terms of composition, corrosion resistance, safety, and suitable applications.
201 stainless steel has a relatively high manganese content, resulting in weaker corrosion resistance and insufficient tolerance to acids, alkalis, and salts. When used over long periods to hold soups, vinegar, pickled foods, or exposed to humid environments, it is prone to oxidation, yellowing, and the formation of rust spots. Its material stability is moderate, making it unsuitable for prolonged use as tableware; it is best reserved for ordinary hardware items that do not come into direct contact with food.
304 is a widely used material for food contact, with a well-balanced composition and stable resistance to acids, alkalis, and oxidation. It effectively prevents rusting and spoilage when used to hold hot or cold meals, soups, and fruits and vegetables. Its robust structure ensures that it does not readily leach harmful substances under normal conditions, making it suitable for everyday household tableware, serving dishes, kitchen utensils, and other common applications. Overall, it offers moderate practicality.
316 stainless steel builds on the 304 base by optimizing its alloy composition, further enhancing its corrosion resistance and resistance to salt and acids. It delivers superior oxidation and corrosion resistance when exposed to high-salinity environments, acidic foods, and prolonged humidity or variable outdoor conditions. Its microstructure is more stable, broadening its range of applications and making it particularly well-suited for infant and toddler tableware, portable lunch boxes, and scenarios involving long-term outdoor use or frequent handling of strongly flavored foods.
Overall, the three material grades improve progressively: 201 is not suitable for food‑grade tableware, 304 meets everyday household needs, and 316 offers superior all‑round corrosion resistance. Choose accordingly based on your application environment and requirements.
