What Are The Advantages And Disadvantages Of Stainless Steel Cups
Stainless steel cup material is generally 201, 202 and 304 stainless steel, the most common two are 304 and 201 stainless steel.
It can be judged from the following points.
1.304 stainless steel corrosion resistance, high price: 201 stainless steel and 304 stainless steel material in essence, the main difference is that the two contain different elements. The corrosion resistance and stamping performance of 304 stainless steel is much better than that of 201. Moreover, 304 stainless steel is generally used in places where the environment is complex and the corrosion resistance is strong. 201 stainless steel is used in places where the environmental requirements are not high or the stainless steel quality is not high.
2.304 stainless steel prices are higher: in terms of price, 304 is also far higher than the 201 price. Because 304 quality is better than 201 stainless steel, and 304 for imported stainless steel plate, 201 for domestic stainless steel plate, so the price of 304 is naturally higher.
3.304 the toughness of stainless steel is better: 201 stainless steel is hard, with steel and easy to crack. The 304 stainless steel insulation cup contains nickel, so it does not rust, and 304 stainless steel is more tough, fatigue resistance is much better than 201.
4.201 stainless steel easy to rust: 201 stainless steel with high manganese content, the surface is very bright with dark bright, high manganese content easy to rust. The 304 stainless steel thermos cup contains more chromium, and the surface is matte and does not rust. When choosing stainless steel thermos cups, the difference between the two cups is obvious. (potable water can be used as an experiment).
5.304 stainless steel cup is not easy to rust because the formation of chromium-rich oxides on the surface of the steel can protect the steel, thus achieving the effect of healthy drinking water. The 201 stainless steel belongs to high manganese stainless steel, which is larger than 304 hardness, high carbon and low nickel.
