1. What Is High-Carbon Steel?

High-carbon steel is a type of steel that contains more than 0.5% carbon, typically ranging from 0.6% to 1.0%. With a higher carbon content than standard steel, it offers exceptional hardness, abrasion resistance, and tensile strength making it ideal for applications requiring precision and endurance, such as knives, scissors, saw blades, molds, and springs.

Its main components include iron and carbon, along with small amounts of manganese, silicon, sulfur, or phosphorus. The elevated carbon level allows the steel to maintain a sharp edge for a long time and resist wear, though it can also make it more brittle and difficult to weld compared to low-carbon steel. To balance hardness and toughness, high-carbon steel is often heat-treated and tempered.

Common types of high-carbon steel include:

• Tool steel: Contains elements like tungsten, molybdenum, and chromium to enhance hardness and heat resistance often used in making knives and cutting tools.

• Spring steel: Heat-treated for high elasticity, commonly used in automobiles and mechanical equipment.

• Damascus steel: A traditional patterned steel, famous for its use in Japanese swords and premium knives.

In knife-making, high-carbon steel is prized for achieving a sharper and more precise edge than stainless steel. However, it’s prone to oxidation, requiring regular drying and maintenance to prevent rust. Despite this, its unmatched sharpness and durability make it the top choice for premium Japanese kitchen knives, trusted by professional chefs worldwide.
