What are the stainless steels that can be used to make tableware
Although the material of stainless steel has many advantages, in fact, not all stainless steel can be used to make tableware. Stainless steel is also divided into many different types. Each type of stainless steel has its own function, especially for making tableware. The stainless steel of tableware has strict requirements and regulations.
After being made into tableware, stainless steel will come into direct contact with food. If it does not meet the standards, it is very likely to endanger our health. Therefore, our country is also conducive to strict regulations on food and stainless steel that are in direct contact with food.
At present, only stainless steel that meets the national mandatory standard GB4806.9-2016 "National Food Safety Standard for Food Contact Metal Materials and Products" can be called food-grade stainless steel. In this standard, arsenic, cadmium, lead in stainless steel products The upper limit of migration of five heavy metals such as , chromium and nickel under specific measurement methods is limited.
The 304 stainless steel we are more familiar with is a food-grade stainless steel, which can be used to make ordinary bulk tools. In addition to this, there is also 316 stainless steel. The nickel content of 316 stainless steel is higher than that of 304, so the corrosion resistance is better and stronger. , and other elements are added in the production process, so this 316 stainless steel is mainly used in the food industry or surgical equipment.
When we buy stainless steel tableware or other kitchen utensils, we must see whether it is marked with 304 or 316. We must not buy other types of stainless steel, especially low-quality stainless steel, which may contain some heavy metal elements. health is also at great risk.
