Supreme Steels

H13

Product Description:

H13 is a high-performance chromium-based hot work tool steel that is widely used for manufacturing tools and dies that operate under high temperatures and stress. Known for its excellent resistance to thermal fatigue, wear, and high-temperature strength, H13 is one of the most popular tool steels used in hot work applications, such as die-casting, extrusion dies, and forging tools. It offers a unique combination of toughness, heat resistance, and durability, making it suitable for tools that are subjected to thermal cycling and heavy mechanical stress.
