H-11 Tool Steel

H-11 tool steel is a type of chromium hot work steel that is commonly used for manufacturing hot-work dies and tools. It is known for its high resistance to thermal shock and excellent toughness. H-11 tool steel contains a combination of alloying elements, including chromium, molybdenum, and vanadium, which contribute to its high-temperature strength and wear resistance.

H-11 tool steel can be hardened by heat treatment and is often used in applications that require high strength, toughness, and resistance to thermal fatigue. It is commonly used in the manufacture of hot-work dies, extrusion dies, forging dies, and punches. H-11 tool steel can also be used for other applications, such as plastic injection molding, where high-temperature performance and wear resistance are important.
