304 stainless steel that is used to make vacuum flasks can be said to have experienced a long period of evolution, and finally is considered one of the most suitable raw materials for the manufacture of stainless steel vacuum flasks by international authorities.
Stainless steels are divided into many series. Austenitic stainless steel is the only standard material of stainless steel thermos after the period of the experiment and conclusion. 304 stainless steel belongs to one of the austenitic stainless steel series.
Let's take a look at 304 stainless steel and see how it stands out from the other stainless steel.
The difference among various stainless steel is mainly reflected in that elements in those steels are not the same, 304 stainless steel thermos's corrosion resistance and stamping performance are far better than other models of the thermos.
And 304 stainless steel vacuum flask jug is generally used in a complex environment that needs strong corrosion-resistance, 201 material thermos flask is used for the environment without very high requirements or high stainless steel material requirements.
201 stainless steel is hard with a little toughness and is easy to crack. While 304 stainless steel vacuum flask will not be rusty because it contains nickel. What's more, the 304 stainless steel vacuum flask is more resilient and has better endurance than the 201.
304 stainless steel vacuum flask is hard to get rusty, and stainless steel vacuum flask made of 304 stainless steel contains more chromium. The surface of the bottle is matte and not rusty. In the purchase of stainless steel vacuum flask, the difference between the 201 and 304 stainless steel vacuum flask is obvious.
304 stainless steel thermos is not easy to rust because the chromium-rich oxide is shaped on the surface of the steel, which can protect the steel body, so as to achieve healthy drinking.
In the early days of the establishment of the People's Republic of China, there is no stainless steel thermos flask. What are existed are only the bottle, cup, and so on. And the bottle at that time is made of aluminum alloy through casting. There is still a very huge gap between aluminum alloy casting and forging when it comes to the casting industry.
With the development of the times, this kind of bottle and cup through the most original casting have been knocked out slowly, which are laterly evolved into plastic bottle, iron bottle, stainless steel customized vacuum flask and so on. Until today, 304 stainless steel thermos flask is recognized by the majority of consumers.
