Because of my work, I share knowledge about water bottles with everyone every day. The most talked about topics are safety and health. The material used in the stainless steel water cup must be food grade, and it must be food grade stainless steel marked 304 stainless steel or 316 stainless steel or above. I believe many friends have a fairly in-depth understanding of it after it has been popularized by us. Some friends asked you that drinking water from drinking glasses comes into contact with the human body and water, so it must be food grade. What about the stainless steel cutlery, stainless steel tableware, stainless steel pots and basins, and stainless steel shovels and spoons used for cooking? ? These are also in contact with food every day. Should kitchen supplies also be made of stainless steel materials above grade 304 or 316?
Answer: yes
However, when seeing this answer, some manufacturers who produce related products will definitely sneer at it, thinking that they don’t understand anything and just talk about it.
We really don’t know much about industries other than water cups. Even the knowledge of the water cup industry is limited. However, in a strict sense, it is still in contact with people and food. So in accordance with international standards, these related stainless steel tableware Kitchen utensils should indeed be food grade.
We once visited Jieyang, a city that mainly produces stainless steel kitchenware, and asked the person in charge of some factories that produce stainless steel Western-style food knives and forks. I think one of the explanations given by the other party is somewhat reasonable. Knife and fork products are not as Water cups are in contact with water for a long time, and people still have to drink them. At the same time, due to the hardness of 304, and the hardness of 316 is so high that the cost is too high. Taking into account the wear resistance of cutlery and production costs, customers need Or 430 stainless steel will be used if there are no special requirements in the market. At the same time, this material has been exported to the world from the past to the present.
The other party also said that as long as it requires the use of 304 stainless steel, the other party can also use 304 stainless steel as required. The editor also asked the other party to quote for the same product. It is true that 304 stainless steel is higher than 430 stainless steel. As for how much higher, in order to avoid being cast aside by my peers, please let me avoid this question.
We don’t know much about 430 stainless steel. We probably don’t know as much as you can search online, but 430 stainless steel is indeed used more in our kitchen supplies, including the fruit knives we use in our lives. Kitchen knives, etc.
Some friends will ask whether 430 stainless steel will rust. The editor will tell you with limited knowledge that when you find that the stainless steel products such as knives and forks you use start to rust, most of them mean that the stainless steel of this product is 201 or even worse. The corrosion resistance of 430 is quite good.
