Is carbon important in 304 stainless steel pipe? 2018-11-29 When it comes to carbon, everyone will think of diamond, because diamond is a substance made of carbon, which also proves the role of carbon, so does carbon have the same role in 304 stainless steel tubes? In fact, carbon is one of the main elements in industrial steel. The performance and structure of steel are determined by the content and distribution of carbon in it. The effect of carbon on the structure of stainless steel pipes is mainly manifested in two aspects. One is The element that stabilizes austenite, and the effect is about 30 times that of nickel; the second is that carbon and chromium have a relatively large affinity, and will form a series of complex carbides with chromium, thereby affecting the role of chromium in stainless steel. Therefore, the carbon element in the 304 stainless steel tube can increase the hardness of the stainless steel tube, but as the carbon content increases, the corrosion resistance of the stainless steel tube decreases, and the plasticity becomes worse. And these two contradictory influence laws also make people choose stainless steel pipes with different carbon content for different use requirements. In our daily life, stainless steel pipes mainly take corrosion resistance as the main function, and the carbon content is very low for the requirements of some processes (such as easy welding, bending, etc.). The production of 304 stainless steel pipes strives for perfection from the raw material steel strip, and strictly controls the carbon content of the 304 stainless steel pipes. This is the stainless steel brand you should choose for quality.
