Bottled joy：Is there any harm to the stainless steel sports bottle?

The stainless steel 2.5l water bottle is made of iron-chromium alloy mixed with nickel and other metals. Many of the elements in it are trace elements required by the human body, such as iron and manganese. The water quality we quoted, whether it is mineral water, tap water, or well water, also contains trace elements.

Under normal circumstances, we use stainless steel products for a time limit. For example, it takes only a few minutes to a few hours or even dozens of hours to fill water in a vacuum flask. According to the test results, the dissolution of metal components is very limited during this time. It is lower than the requirements of domestic and foreign standards. Therefore, as long as it is used correctly, the harm of stainless steel tableware to the human body is minimal.

In addition, pay attention to buying food-grade stainless steel sports bottles. Cheap stainless steel sports bottles on the market are usually poisonous. Let's take a look at the characteristics of the materials of different specifications of stainless steel sports bottles.

430 stainless steel (13-0): Can not resist the oxidation caused by chemicals in the air. After a period of infrequent use, it will still be oxidized (rusted) due to unnatural factors.

304 stainless steel (18-8): can resist chemical oxidation. 304 is a material that must be used in the national pressure cooker standard. The standard material of stainless steel pressure cookers is above 304. Because there are not many pressure cooker production factories approved by the state, these factories are very honest.

316 stainless steel (18-10): high-end products are made of 10% nickel to make them more durable and corrosion-resistant. This kind of stainless steel is called 18-10 stainless steel, which is also "medical stainless steel". There is no metal ion precipitation at all. It is non-toxic, in other words, food-grade stainless steel that meets the standard is also a common material for all stainless steel 2.5l water bottles.
