It is often asked that “the harder the stainless steel pipe is, the better?” Many users will think that the harder the stainless steel pipe, the better the quality of such stainless steel pipe, especially the stainless steel security window and railing handrail. The stronger, but is the actual situation like this?
Before tangling this problem, let us first understand the type of elements contained in the stainless steel tube. The stainless steel tube contains metal elements such as nickel, chromium, copper, carbon, sulfur, phosphorus and manganese. It determines that the hardness of the stainless steel pipe is carbon, because the main characteristic of carbon is to make the object hard, and the hardness of the stainless steel pipe increases as the carbon content increases.
However, the carbon element has two sides. As the carbon content increases, the plasticity and toughness also decrease, and the welding, cold bending and corrosion resistance also show a significant decrease. The higher the carbon content, the lower the content of other metals, so to understand the characteristics of the stainless steel tube, you can not blindly buy the wrong stainless steel tube.
