High-carbon stainless steel is a type of steel that contains a higher percentage of carbon compared to standard stainless steel. This increased carbon content enhances its hardness and strength, making it suitable for applications that require durability, such as knives and cutting tools. In addition to carbon, high-carbon stainless steel also contains chromium, which provides corrosion resistance. This combination of properties allows it to maintain a sharp edge while resisting rust and staining, making it a popular choice in both industrial and culinary settings.
