X100CrMoV5 / 1.2363 is a widely used high-carbon, high-chromium cold work tool steel according to the German standard DIN EN ISO 4957. It is known for its high hardness, excellent wear resistance, good hardenability, and certain corrosion resistance. After proper heat treatment, this steel grade can maintain excellent dimensional stability, making it suitable for high-load precision molds and cutting tools. Due to its outstanding performance, many countries have established equivalent steel grades, such as the American A2 (ASTM A681), the Japanese SKD12 (JIS G4404), and the Chinese Cr5Mo1V (GB/T 1299).
Steel grade 1.2363 contains high levels of carbon and chromium, with additions of molybdenum and vanadium. These elements are key to forming hard carbides, improving wear resistance, and enhancing secondary hardening capability. The chromium content significantly increases the steel's hardenability and corrosion resistance, while the addition of molybdenum and vanadium refines the grain structure, improves toughness, and enhances high-temperature performance. This makes it highly suitable for applications that require high durability, high precision, and good resistance to tempering softening.
