People are often asked, "Is the harder the stainless steel pipe, the better?" Many users think that the harder the stainless steel pipe, the better the quality of the stainless steel pipe, especially for stainless steel anti-theft windows and railings, the higher the hardness of the pipe. The more sturdy, but is the actual situation like this?

Before we entangle this problem, let's first understand the element types contained in stainless steel pipes. Stainless steel pipes contain nickel, chromium, copper, carbon, sulfur, phosphorus, manganese and other metal elements. Among them, the hardness of stainless steel pipe is determined by carbon element, because the main characteristic of carbon element is to make the object hard, and the hardness of stainless steel pipe will increase with the increase of carbon content.

However, carbon has two sides. When the carbon content increases, the plasticity and toughness will also decrease, and the welding, cold bending and corrosion resistance properties will also decrease significantly. The higher the carbon content, the lower the content of other metals. Therefore, to understand the characteristics of stainless steel pipes, you cannot blindly buy the wrong stainless steel pipes.
