The stainless steel used in the water cup is required to be food grade 304. Does the stainless steel of kitchen utensils also have to be food grade?

The reason for the editor's work is to popularize the knowledge of water cups with everyone every day, and the most talked about is safety and health. The material used for stainless steel water cups must be food-grade, and must be food-grade stainless steel marked above 304 stainless steel and 316 stainless steel. I believe that many of our friends have a very in-depth understanding of what we have popularized.

Some friends asked that drinking water from a cup is in contact with the human body and water, so it must be food-grade. What about stainless steel cutlery, stainless steel tableware, stainless steel pots and pans, stainless steel shovels and spoons for cooking? These are also in contact with food every day, should kitchen utensils all be stainless steel materials of 304 or 316 grades or above?

Answer: yes

However, after seeing this answer, some manufacturers who produce related products must sneer at the article, thinking that the editor doesn't understand anything and just rants.

The editor does not know much about industries other than water cups. Even the knowledge of the water cup industry editor is limited, but in a strict sense, it is still in contact with people and food, so according to international standards, these related stainless steel kitchen utensils should indeed be food grade.

The editor once visited Jieyang, a city that mainly produces stainless steel kitchen utensils, and asked the heads of some factories that produce stainless steel western cutlery and forks, and one of the explanations given by the person in charge I think should be somewhat reasonable. Unlike water cups, cutlery and fork products need to be in contact with water for a long time for drinking.

At the same time, due to the hardness of 304, the hardness of 316 is so high that the cost is too high. Considering the wear resistance of the cutlery and the production cost, 430 stainless steel will be used when the customer or the market has no special requirements. At the same time, this material has been exported to the world from the past to the present.

The other party also stated that as long as the request must be made of 304 stainless steel, the other party can also use 304 stainless steel material as required. The editor also asked the other party to quote for the same product that 304 stainless steel is indeed higher than 430 stainless steel.

The editor doesn't know much about 430 stainless steel, and I probably don't know as much knowledge as you have searched from the Internet. But 430 stainless steel is indeed more used in our kitchen supplies, including the use of fruit knives, kitchen knives, etc. in our lives.

Some friends will ask if 430 stainless steel will rust. The editor tells you with limited knowledge that when you find that the stainless steel products such as knives and forks you use begin to rust, most of them indicate that the stainless steel of this product is 201 or even worse. The corrosion resistance of 430 is still good.
