In fact, this is a relatively specialized problem. The basics are now stainless steel tubes of 304 and 201. There are two factors that affect the hardness of stainless steel tubes: annealing of steel strips and carbon content of stainless steel tubes.
One factor is the problem of annealing the steel strip of stainless steel tube. The quality of the annealing of the strip is directly related to the hardness of the stainless steel tube. Both the 201 and 304 stainless steel tubes have corresponding standards for their hardness.
Another factor is the carbon content in the stainless steel tube. The main role of carbon in the stainless steel tube is to increase the hardness of the tube. However, carbon is also an impurity in stainless steel. The more the content is harder, the chance of rusting the tube is also It will be bigger. Xiyouwo stainless steel has a high copper content. Pipes of the same specification thickness are more soft and easy to process and make shapes. It is a good choice.
