Specifications:
Food-grade stainless steel refers to the part of food machinery that contacts food, and must meet certain food safety requirements. Because a lot of acid and alkali are used in the food production process, and stainless steel contains chromium, unqualified stainless steel will dissolve chromium in various price levels, which is toxic; and it is required to limit the content of various alloy impurity elements such as lead and cadmium.
