Stainless steel vacuum cup 304 material stainless steel can be said to have experienced a long period of evolution, and finally was considered by international authorities as one of the raw materials for the manufacture of vacuum cup products. Stainless steel material is divided into many series, but also after a period of experiment, the conclusion of the final establishment of austenitic stainless steel is the material standard of the thermos, 304 stainless steel belongs to one of the austenitic stainless steel series. Xiaobian will lead you to see how 304 stainless steel stands out in the stainless steel series:
304 stainless steel corrosion resistance – stainless steel material series difference is mainly reflected in the various elements are not the same. 304 stainless steel corrosion resistance and stamping performance is far better than other models, and 304 stainless steel is generally used in a complex environment, the need for strong corrosion resistance, 201 is used for environmental requirements are not very high, or stainless steel material requirements are not high.
304 stainless steel toughness is better — 201 stainless steel material is hard, with some steel, easy to crack. The 304 stainless steel thermos cup contains nickel, so it does not rust, and 304 stainless steel is more ductile, fatigue resistance is much better than 201.
304 stainless steel is not easy to rust — and 304 stainless steel thermos made of more chromium, matte surface, do not rust. In the purchase of stainless steel thermos, put the two cups side by side and the difference is obvious.
304 stainless steel thermos is not easy to rust because the formation of chromium rich oxide on the surface of the steel body can protect the steel body, so as to achieve the effect of healthy drinking water. In the early days of the founding of new China, there is no domestic vacuum cup this concept, only the concept of kettle, cup, and so on, and the kettle is made of aluminum alloy casting, when it comes to the casting industry, we have to understand the difference between aluminum alloy casting and forging is still very big. With the progress of The Times, this original process casting kettle, cup was slowly eliminated, later evolved into plastic kettle, iron kettle, thermos cup and so on, until today’s 304 stainless steel thermos cup is recognized by the majority of consumers.
