Martensitic steel is a type of stainless steel known for its high strength and hardness. It is created through a specific heat treatment process that transforms the steel's microstructure, making it suitable for applications requiring durability and wear resistance. This steel is often used in tools, knives, and various industrial components. The unique properties of martensitic steel come from its carbon content, which typically ranges from 0.1% to 1.2%. This allows it to achieve a balance between toughness and hardness. However, it can be less resistant to corrosion compared to other stainless steel types, such as austenitic steel.
