The chemical composition of 1. steel includes carbon, chromium, molybdenum, vanadium, and silicon. The presence of these elements imparts high-temperature strength, toughness, and wear resistance to the steel, making it suitable for use in applications that involve high heat, pressure, and mechanical loads. And its chemical composition is as follows:
1. steel is commonly used for the production of hot-work tools such as forging dies, extrusion dies, punches, and mold inserts. These tools are subjected to high temperatures, pressure, and mechanical stress, and therefore require a material that is reliable and can withstand these conditions. The high degree of toughness and heat resistance of 1. steel makes it ideal for such applications.
In addition to its mechanical properties, 1. steel also exhibits good machinability and grindability, which allows for easy fabrication and finishing of tools made from this material. The steel has good resistance to thermal fatigue and cracking, which contributes to its longevity and durability.
Overall, 1. steel is considered to be one of the most versatile tool steels on the market today. Its high-temperature strength, toughness, and wear resistance make it suitable for a variety of hot-work tool applications. Its excellent machinability and grindability also contribute to its widespread use. For these reasons, tool steel grade 1. continues to be a popular choice in many industrial settings.
While both are hot work steels, 1. is slightly tougher, while 1. (H13) offers higher hot hardness.
When selecting an equivalent of 1. for a project, consider:
Working Temperature: H13 (1.) is better for very high temps.
Toughness Needs: 1. offers superior crack resistance.
Regional Availability: AISI H11 is more accessible in North America.
Finish Requirements: For polished molds, ensure high purity versions.
