304 stainless steel has strong corrosion resistance - the main difference in the stainless steel material series is that it contains different elements. The corrosion resistance and stamping performance of 304 stainless steel are far better than other models, and 304 stainless steel is generally used in areas with complex environments that require strong corrosion resistance. 201 is used in areas with low environmental requirements or low requirements for stainless steel materials.
304 stainless steel has better toughness -201 stainless steel has a harder material with a bit of steel and is more prone to cracking. The 304 stainless steel insulation cup contains nickel element, so it does not rust. Moreover, 304 stainless steel is more resilient and has much better fatigue resistance than 201.
304 stainless steel is not easy to rust - while the insulation cup made of 304 stainless steel contains more chromium, and the surface appears matte and does not rust. When choosing a stainless steel insulated cup, it is obvious to compare the two types of cups together.
The reason why 304 stainless steel insulation cups are less prone to rusting is because the formation of chromium rich oxides on the surface of the steel body can protect the steel body, thereby achieving the effect of healthy drinking water. In the early days of the founding of the People's Republic of China, there was no concept of insulation cups in China. At that time, there were only concepts such as water bottles and cups, and at that time, water bottles were all made of aluminum alloy casting. When it comes to the casting industry, we need to understand that there is still a significant difference between aluminum alloy casting and forging. With the progress of the times, this primitive process of casting water bottles and cups was gradually phased out, and later evolved into plastic water bottles, iron water bottles, insulation cups, and so on, until today's 304 stainless steel insulation cups are recognized by the majority of consumers.
