Material and Safety of Stainless Steel Insulated Cups
Stainless steel insulated cups are widely welcomed for their excellent insulation performance and durability. Its main material is 304 or 316 stainless steel, both of which meet food safety standards and do not contain harmful heavy metals to the human body. 304 stainless steel is a food grade stainless steel with good corrosion resistance and heat resistance; 316 stainless steel goes further by adding molybdenum element, which has stronger corrosion resistance and is suitable for more harsh environments. When choosing a stainless steel insulated cup, one should identify the material label to ensure the safety of the product.
