304 vs 301 stainless steel tube
The material of stainless steel tube is different, which is mainly embodied in the performance. For example, 301 and 304 of the two kinds of stainless steel tubes, although all of the 300 series, but there is a great difference between them. Do not pay attention at the time of purchase, can be misleading.
The difference between the 304 and 301 stainless steel tubes
304 vs 301 stainless steel
1. chemical composition:
301 stainless steel tube
C：≤0.15 ，Si：≤1.0 ，Mn：≤2.0 ，Cr：16.0～18.0，Ni：6.0-8.0，S：≤0.03.
304 stainless steel tube
C：≤0.08，Si：≤1.0，Mn：≤2.0，Cr：18.0～20.0，Ni：8.0～10.5，S：≤0.03.
The difference in chemical composition is that the carbon content of the 304 - 301 stainless steel tube is low, and the content of nickel and chromium is higher.
2. mechanical properties：
the corrosion resistance and ductility of 304 stainless steel pipes are better than those of 301 stainless steel pipes. The hardness of 301 stainless steel pipes is higher, so its wear resistance and fatigue strength are better than those of 304 stainless steel pipes.

3. use:
301 stainless steel tubes are generally used for elastic use, such as the production of springs. The 304 stainless steel tube has good corrosion resistance, which is usually used in food, kitchen and sanitation, water treatment and so on.

4. price:
304 stainless steel tube is more expensive than 301 stainless steel tube. Some unscrupulous merchants on the market sell 301 to 304 to deceive consumers. When purchasing, we should pay attention to the supply side.

Summary: when you buy stainless steel tubes, we must first clear their own uses, and then find the suitable stainless steel tubes. In order to prevent the use of the stainless steel pipe to find not suitable, waste human resources and financial resources.
