Whether the carbon content will affect the stainless steel material?

     The stainless steel profile contains a certain amount of carbon, which is an element that stabilizes the stainless steel profile and has a large degree of action. The carbon content and its distribution form to a large extent determine the performance and organization of stainless steel profiles. Today we will take a look at the impact of carbon content on the properties of stainless steel profiles.


    The difference in carbon content of stainless steel profiles will result in differences in the strength and corrosion resistance of the material. Various steels have better corrosion resistance, but the strength is lower than that of profiled steel. This material is mostly used to manufacture structural parts. The latter two steel grades can obtain high strength due to high carbon content. They are used to manufacture springs and tools. High strength and wear resistant parts. In order to overcome the intergranular corrosion of 18-8 chrome-nickel stainless steel, the carbon content of the steel can be reduced to less than 0.03%, or an element (titanium or tantalum) having a greater affinity than chromium and carbon can be added to prevent carbonization. chromium. For example, when high hardness and wear resistance become the main requirements, we can increase the carbon content of steel while increasing the chromium content, so as to meet the requirements of hardness and wear resistance, and also take into account the corrosion resistance. Features.

    At present, the carbon content of Dachangxu stainless steel profiles used in the industry is relatively low. Most of the stainless steel profiles contain between 0.1 and 0.4% carbon, and the acid-resistant steels are mostly composed of 0.1 to 0.2% carbon. Stainless steel with a carbon content greater than 0.4% accounts for only a small fraction of the total number of steel grades because stainless steel profiles are always primarily resistant to corrosion under most conditions of use. In addition, the lower carbon content is also due to certain process requirements such as ease of soldering and cold deformation.

    Therefore, from the viewpoint of the strength and corrosion resistance of the material, the role of carbon in the stainless steel profile is mutually restrained. Stainless steel profiles with high carbon content have a relatively high strength, and profiles with low carbon content have high corrosion resistance. Therefore, when you purchase, you can choose different carbon content profiles according to different usage requirements.
