Stainless steel tableware is more corrosion-resistant than other metals. The utensils made of stainless steel are beautiful and durable, and are more and more loved by consumers. When selecting stainless steel tableware, carefully check whether the material and steel grade used are marked on the outer package. So, should we choose stainless steel tableware correctly?
1. When purchasing stainless steel products, carefully check whether the material and steel grade used are marked on the outer package, and whether the manufacturer's factory name, address, telephone and container hygiene standards are marked.
2. Generally, for stainless steel tableware of the same thickness and shape, the weight of high-grade tableware will be heavier than that of low-grade tableware. However, the density difference is very small. The density of 304 stainless steel is 7.93430 and 420, and the density is 7.85
3. Don't be greedy for cheap. Go to the stall to buy the so-called stainless steel products. Don't buy those fake and shoddy products, otherwise it may harm human health.
4. There are three codes "13-0", "18-0" and "18-8" printed on the tableware. The tableware is made of stainless steel. The number in front of the code represents the content of chromium and the number behind represents the content of nickel.
