Many people engaged in the stainless steel industry know something, that is, stainless steel is divided into 200 series, 300 series and 400 series, of which the most common is the scope of 200 series. However, sometimes we say stainless steel may be 400 series, but many people can't distinguish it clearly. Then you will say, what's the difference between 400 series and 200 series? Why not use 200 series, Or 201?

Let's talk about the model performance of stainless steel. Among the three models of 200 series, 300 series and 400 series, there are many subdivided models, preferably in the field of 300 series. However, the application of 200 series and 400 series depends on the subdivided models. 201 and 409 are similar, but the performance of 409s and 410430 is slightly better than that of stainless steel 200 series, so many regions can't afford to use 300 series, The 400 series will be used instead of the 200 series. For example, the water cups in many countries are made of 400 series materials instead of 200 series. This is not the case in a country, even in some developed regions, which shows that the performance of the 400 series is better than that of the 200 series in some fields.

When choosing different materials in different fields, we should focus on people's living standards, health factors and other considerations. Not to mention the safest, at least we should reduce the hidden dangers to a relatively low position.
