The type of stainless steel represents the different alloy content of stainless steel. In today's online sales, how do we choose materials according to the type of stainless steel? Zibo Baishun Stainless Steel Co., Ltd. provides you with methods.


304, 316 stainless steel is the first choice for tableware


316L stainless steel

To choose tableware such as bento boxes, 304 and 316 stainless steel are the most suitable. 304 stainless steel is commonly known as "white iron" in Taiwan. It has good corrosion resistance and is the most widely used, including industry, furniture decoration industry and food and medical industry. 316 medical grade stainless steel contains a more molybdenum (Mo) element than 304 stainless steel, so it is more corrosion resistant, stronger, and more expensive, making it the second most widely used stainless steel. Suitable for fertilizer production equipment, photography, food industry, coastal facilities.


430 stainless steel meets food grade standards and the price is lower

430 stainless steel


430 stainless steel does not contain nickel, and its price is lower than that of 304 and 316 stainless steel. It is often used in the inner layer of kitchen utensils, dishwashers and washing machines. However, its corrosion resistance is not as good as 304 and 316 stainless steel, and it is easy to rust in long-term use. 430 stainless steel has good corrosion resistance to nitric acid, and it is the most widely used in automotive trims and related components. When resolving, you can use a magnet to suck the bottom of the appliance. If it can be sucked, it is 430 stainless steel. If it cannot be sucked, it may be 304 or 316 stainless steel.


The 200 series is more likely to rust, but the FDA says there are no safety concerns


202 stainless steel

It needs to be clarified that the 200 series of tableware will not dissolve too much "manganese" metal because of the food. According to the dissolution test results of manganese stainless steel in 101 for different materials in 101 years, if 4% acetic acid is used as the solvent (placed at 60 ° C for 30 minutes), the dissolution of manganese in 200 series steel is up to 4.39 ppm (mg / kg) For example, drinking a bowl of about 200 g of soup (contained in a 200 series stainless steel container) and ingesting only 0.88 mg of manganese is much lower than the manganese (3.77 mg) ingested by daily consumption of a bowl of brown rice (based on 80 g of brown rice). Although there are many negative rumors about 200 series stainless steel on the Internet, there is no scientific proof that it is harmful to the human body, and the public need not worry too much.
