The difference between stainless steel 201 and 304 pipes

What is the difference between stainless steel pipe 201/304?

The most fundamental problem with stainless steel pipe 201/304 is that the metal elements that make up the pipe are different, and the main elements Ni and Cr are different in content. Different combinations of metal element contents form different materials (201/304/316, etc.).

The price of stainless steel has always been a very important issue in the industry, and the fluctuations in price increases are also very obvious. However, the price of 304 and 201 are always much more expensive. Why is this?

As mentioned above, the fundamental difference between 201/304 is that the content of metal elements is different, and Cr and Ni are precious metals. The stainless steel made of 304 has much more Cr and Ni than 201, so the price of 304 will be much more expensive!

How to choose 201/304?

1.Choose according to usage

The biggest advantage of 304 compared to 201 is the anti-oxidation and anti-corrosion capabilities of the pipe.

Therefore, it is very important to purchase 201/304 materials according to the actual use method when purchasing.

If the usage environment is harsh, such as contact with liquids (water, corrosive liquids, etc.), humid climate all year round (coastal areas), outdoor construction, etc., it is recommended to purchase pipes made of 304 material. If it is just for some indoor use or ordinary building construction, just choose 201 material.

2. Choose according to budget

If you have a larger budget and pay attention to quality, then pipes made of 304 material are the best choice.
