[Professional Reveal] How much do you know about food-grade stainless steel thermos?

Hello everyone, today I have a title party. The content is not so scary, nor so dark. But for you, maybe you really don’t know much about thermos cups, www.zhanyict.comand maybe you really don’t know much about food-grade stainless steel, so today I will share with you food-grade stainless steel and thermos cups made of food-grade stainless steel.

What is Food Grade Stainless Steel?

Food-grade stainless steel, as the name implies, is a stainless steel material that can come into contact with food without causing harm to food. At present, food-grade stainless steel is mainly 304 stainless steel and 316 stainless steel. Our daily life, especially the maintenance of life, is inseparable from eating and drinking, so food-grade stainless steel materials are used in products related to our eating and drinking, such as: pots and pans, water cups, kettles, water dispensers, ice machines, chef machines, dishwashers, etc., including chopsticks and props. www.zhanyict.comAmong them, knives are quite special, and the knife-making process has been passed down for thousands of years. In addition to 304 stainless steel, knives on the market are also made of iron-clad steel, other alloy materials and ceramics.

What types of stainless steel should be used for thermos bottles?

As mentioned earlier, food-grade stainless steel is currently mainly 304 stainless steel and 316 stainless steel. Since thermos cups are in contact with water and other beverages for a long time, 304 stainless steel and 316 stainless steel are also used. Many brands and sales merchants will say that 316 stainless steel is medical steel when introducing the material. In fact, this is inaccurate. www.zhanyict.comThe same 316 stainless steel will also have some differences depending on the purpose and environment of use. So although the stainless steel used in medical treatment is 316 stainless steel, it cannot be said that 316 stainless steel is all medical steel. When some merchants produce stainless steel thermos cups, considering the difficulty and cost of processing, they play some edge balls, saying that the part of the stainless steel water cup that contacts water is made of 304 stainless steel and 316 stainless steel, and the outer layer is made of 201 stainless steel. Even if 201 stainless steel is not food-grade stainless steel, there is currently no hard and fast rule that such a production method is illegal.

Compared with 304 stainless steel and 316 stainless steel, 316 stainless steel has higher hardness and better corrosion resistance. However, according to the analysis of the world's well-known testing institutions, 304 stainless steel as the production material of stainless steel water cups has fully met people's daily needs, and it is impossible to distinguish 304 stainless steel from 316 stainless steel through potion testing. www.zhanyict.comAt the same time, the stainless steel water cups produced by 316 stainless steel are almost the same as 304 stainless steel in terms of user experience. The main reason why merchants have produced 316 stainless steel thermos cups is that marketing maintains market differentiation, thereby satisfying consumers' curiosity and market needs.

What are the consequences of long-term use of thermos cups made of unqualified stainless steel or non-food grade stainless steel?

Long-term use of thermos cups made of unqualified stainless steel or non-food grade stainless steel may cause the dissolution of harmful substances such as lead and cadmium, www.zhanyict.comwhich may cause chronic poisoning to health. In addition, non-food grade stainless steel may produce chemical reactions, release harmful substances, and pose potential risks to the body.
