Copper is so important in stainless steel pipes! 2018-11-27 Stainless steel pipe is an alloy material composed of many elements, including nickel, chromium, copper, carbon, iron, manganese and so on. Each element has its own value, just like chromium and nickel elements react with oxygen in the air to form an oxide film attached to the surface of the pipe, which can protect the pipe from corrosion. So what role does copper play? Here is a detailed answer for everyone: 1. Improve the corrosion resistance of stainless steel pipes, but the effect is limited, and there is no obvious effect of nickel and chromium; 2. The deep drawing performance of steel, such as 0Cr18Ni9Cu3, can be made into various corrosion resistance Of rivets. 3. In carbon steel, it increases hardenability and reduces ductility. 4. Adding to antibacterial stainless steel, after exclusive treatment, the precipitated phase has better sterilization effect. 5. In the stainless steel pipe, part of the copper acts as a strengthening element, which makes the precipitation hardening reaction of each element occur, thereby enhancing the tensile strength of the pipe. In addition, copper in those steels that do not undergo precipitation hardening can slightly increase the yield strength-the low stress value when the material begins to undergo significant plastic deformation, that is, the compressive capacity of the pipe is appropriately increased. The above is the role of copper in stainless steel pipes. At the same time, it should be noted that copper and nickel should be added together. In addition, the copper content should not exceed 1.5%, otherwise the steel will become brittle. It is a professional manufacturer of 304 stainless steel pipe. It has a deep understanding of the composition of each element of the pipe and knows how to make the performance of the pipe good. The quality of the product is deeply loved by customers.
