304 stainless steel food safe material
What’s the 304 stainless steel food safe materials ? It is the stainless steel materials produced in strict accordance with the requirements of the national food safety standard (GB9864). It is also known as food-contact stainless steel material. It is currently used in kitchen appliances. , Food, beverages, wine utensils, biological engineering and other production equipment and assembly lines, it is closely related to our lives.
What is the difference between 304 stainless steel food safe materials and normal 304 stainless steel materials : 304 is a one of the basic stainless steel materials, and its offen used for equipment and mechanical parts because of its good comprehensive performance (corrosion resistance and plasticity). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 17% Cr and more than 8% Ni, and 304 stainless steel products are not food safe grade. Only 304 stainless steel materials that have been specially processed and passed the GB 9684 national testing standards can be used for food grade stainless steel products. and the content of Ni and Cr is usually lower than normal steel material, From the cost of raw materials and its performance, 304 stainless steel food grade material is currently the most suitable material for food safe.
However, how can we check the quality of 304 stainless steel food safe material is really safety ? Take the stainless steel tableware container as an example. according to GB 9684-2011, the content of "Pb" in stainless steel is much lower than that of ordinary stainless steel, and the anti-corrosion performance of the product has also increased. the requirement is: Pb ( mg/L 4% acetic acid soaking solution) ≤ 1.0 1.0. Cr (mg/L 4% acetic acid soaking solution) ≤ 0.5. Ni ( mg/L in 4% acetic acid soaking solution ) ≤ 3.01.0. Sn ( mg/L 4% acetic acid solution), ≤ 0.02 . As (mg/L 4% acetic acid solution), ≤ 0.04 . (Note: The soaking conditions are all boiling for 30 minutes and then at room temperature for 24 hours). Therefore, when choosing f 304 stainless steel food safe materials, you should first check the element content in these materials.
