Q:Commonly used tool steel types and their carbon content ranges?

In industrial manufacturing, commonly used tool steel types include high-speed steel, cold work die steel, hot work die steel, alloy steel, etc. Their carbon content ranges are different. Here are some commonly used tool steel types and their carbon content ranges for reference:
1. High speed steel
High-speed steel is an alloy steel containing elements such as tungsten, molybdenum, and cobalt. Its carbon content is usually between 0.75% and 1.4%.
2. Cold work die steel
Cold work die steel is a type of tool steel used to make molds, cutting tools, etc., and its carbon content ranges from 0.40% to 1.20%.
3. Hot work die steel
Hot work mold steel is a tool steel used to make plastic molds, die-casting molds, etc., and its carbon content ranges from 0.25% to 0.50%.
4. Alloy steel
Alloy steel is an alloy steel containing elements such as chromium, molybdenum, and cobalt. Its carbon content is usually between 0.50% and 1.00%.
