D2 steel is a high-carbon, high-chromium, air-hardening tool steel that is commonly used for the following applications:

• Cutting tools: PM T15 is widely used in the production of cutting tools such as drills, taps, reamers, end mills, and saw blades. Its high hardness and wear resistance make it well-suited for machining hard materials.
• Bearings and gears: PM T15 is also used in the production of high-performance bearings and gears. Its high hardness and toughness help to prevent wear and fatigue, even under heavy loads and high speeds.
• Toolholders and fixtures: PM T15 is often used to make toolholders and fixtures for machine tools. Its high hardness and wear resistance make it well-suited for these applications, where it can withstand the repeated stresses and wear associated with metalworking operations.
• Aerospace components: PM T15 is used in a variety of aerospace applications, including turbine blades, jet engine components, and other high-stress parts. Its ability to maintain its mechanical properties at high temperatures makes it well-suited for these applications.
