Other than type 304 steel, can other stainless steel not be used for food?
All kinds of tableware: should choose martensitic stainless steel (0Cr13, 1Cr13, 2Cr13, 3Cr13)The lead content of food grade stainless steel is much lower than that of ordinary stainless steel. General 304 stainless steel is not food grade, specially processed is food grade.
All kinds of food storage containers and food processing machinery should use austenitic stainless steel (1Cr18Ni9Ti, 0Cr19Ni9, 1Cr18Ni9). All kinds of tableware: should choose martensitic stainless steel (0Cr13, 1Cr13, 2Cr13, 3Cr13).
When the heavy metals transferred in the stainless steel products exceed the limit, it may endanger human health. Therefore, stainless steel cookware production needs to find a balance between corrosion protection and safety. If the content of nickel and chromium is high, the anti-corrosion function will be enhanced, but the amount of nickel and chromium will also increase, which means that the risk of safety will increase. 304 stainless steel is a very common stainless steel, the industry is also called 18/8 stainless steel. It is better than the corrosion resistance of 430 stainless steel, high temperature corrosion resistance, good processing performance, so it is widely used in industrial and medical furniture industry and the food industry, for example, some high-grade stainless steel tableware, bathroom and kitchen utensils. 304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 17% chromium, more than 8% of the nickel content.
