martensitic steel
Quick Summary
Martensitic steel is a type of steel characterized by its martensite microstructure. This microstructure is formed when steel is rapidly cooled, or quenched, from a high temperature. During this rapid cooling process, carbon atoms are trapped within the iron's crystal structure, creating a very hard and brittle material.12
Martensitic steels can be further processed through tempering, which involves reheating them to a moderate temperature. This tempering process reduces their brittleness and increases their toughness, resulting in a strong and durable steel.2
There are different types of martensitic steels, including stainless steels, which contain chromium for corrosion resistance, and maraging steels, which are low-carbon martensitic steels with high nickel content that are hardened by aging.34
