Many customers have asked why are products of some manufacturers are more expensive than others for the same style of vacuum sports bottle?
The reason why it is expensive is that we use 304 stainless steel as the raw material of the sports flask to ensure the quality of each product. For stainless steel, there are 304, 201, and 202 models, and the two common ones are 304 and 201 stainless steel.
Although the materials are different, the vacuum sports bottles produced by the two materials look the same, and people can hardly recognize them. Why is the price of 304 stainless steel vacuum sports bottles so high? Here are some points:
The essential difference between 201 and 304 stainless steel is mainly reflected in the different elements contained in the two.
The corrosion resistance and stamping performance of 304 stainless steel are far better than those of 201, and 304 stainless steel is generally used in places where the environment is complex and requires strong corrosion resistance. 201 is used in places where environmental requirements are not very high, or requirements on stainless steel material are not high.
The material of 201 stainless steel is relatively hard, with a little rigidity, and is easier to crack. The 304 stainless steel vacuum flask contains nickel, which is tougher and has much better fatigue resistance than 201.
201 stainless steel contains high manganese, the surface is very bright with darkness. And because of the high manganese content, it is easy to rust. The vacuum flask made of 304 stainless steel contains more chromium, and the surface is matte and does not rust. When choosing a vacuum sports flask, the difference between the two flasks is obvious.
304 stainless steel vacuum sports flask is not easy to rust, because the formation of chromium-rich oxide on the surface of the steel body can protect the steel body, to achieve the effect of drinking healthy water. 201 stainless steel has a high manganese content, which is higher in hardness, higher in carbon, and lower in nickel than 304.
As a professional sports flask supplier, our steel sports bottles are made of food contact materials, allowing you to drink healthier water. If you have any need, welcome to consult us.
