D2 tool steel is a high carbon, high chromium cold work die steel. Although it is not stainless steel, it is widely used in the manufacture of high-end cutting tools and industrial blades due to its excellent hardness and wear resistance. Here are some detailed information about D2 tool steel:
Composition: The typical components of D2 tool steel include high carbon (C), chromium (Cr), molybdenum (Mo), silicon (Si), etc. The reasonable combination of these elements endows D2 tool steel with excellent hardness and wear resistance.
Hardness: D2 tool steel is known for its high hardness, typically reaching a hardness of 60-62 HRC after heat treatment. This keeps the blade sharp, even in frequent use, and can last for a long time.
Wear resistance: D2 tool steel has excellent wear resistance, making it very suitable for manufacturing tools that require long-term maintenance of blade sharpness. This makes it an ideal choice for many professional knives, such as hunting knives and tactical knives.
Cutting performance: The cutting performance of D2 tool steel is also quite good, capable of handling various cutting tasks. It is widely used in industrial fields such as mold manufacturing and cutting tool production.
Rust resistance: Although D2 tool steel is not stainless steel, it has a certain degree of corrosion resistance against some corrosive environments at higher chromium content than some traditional carbon steels. However, compared to stainless steel, special maintenance is still required to avoid rusting.
