This high-carbon martensitic stainless steel is known for its exceptional hardness, corrosion resistance, and wear resistance after heat treatment. For example, a knife blade made from this material can maintain a sharp edge for extended periods, even with frequent use. Its chemical composition includes significant amounts of chromium for corrosion resistance and carbon for hardenability.
The balanced combination of hardness and corrosion resistance makes this steel suitable for a wide range of applications requiring a durable, sharp edge or wear-resistant surface. Historically, it has been a popular choice for cutlery, bearings, and surgical instruments, reflecting its ability to withstand demanding environments. This balance of properties contributes to its continued relevance in various industrial and consumer applications.
