The Role Of Carbon In Stainless Steel Wire

Mar 01, 2021

The carbon in the stainless steel wire will reduce the corrosion resistance, plasticity, toughness and weldability of the steel. This is because carbon and chromium have a strong affinity and can form a series of complex carbides with chromium. The higher the carbon content in steel, the more chromium carbide is formed. As a result, the chromium content in the solid solution decreases, and the corrosion resistance of steel also decreases. The higher the carbon content in steel, the lower its corrosion resistance. For stainless steel wire, corrosion resistance is the main requirement, so the carbon content in stainless steel wire is generally very low, mostly only 0.10%-0.20%, generally not more than 0.4%. Carbon can increase the hardness, wear resistance and strength of steel by increasing its content. This is because the strength of stainless steel wire increases as the carbon content in the steel increases. With the increase of carbon content in steel, the hardness, wear resistance and strength of quenched steel will correspondingly increase, but the plasticity and toughness will correspondingly decrease, and the corrosion resistance will correspondingly decrease.
