D2/1.2379 steel
D2/1.2379 steel
D2/1.2379 steel is a high-carbon, high-chromium tool steel that belongs to the group of cold-work steels. It was developed in the early 20th century by the German company Thyssen Krupp for use in cutting and forming tools. D2/1.2379 steel is known for its high wear resistance and toughness, which makes it a popular choice for making knives, dies, punches, and other cutting tools.

D2/1.2379 steel Composition
D2/1.2379 steel has a high hardness and excellent wear resistance, which makes it ideal for making cutting tools that are subject to heavy wear and tear. It also has high toughness, which means it can withstand shock and impact without cracking or breaking. However, D2/1.2379 steel has only fair corrosion resistance and can rust if not properly maintained.
D2/1.2379 steel is typically heat treated using a process called quenching and tempering. This involves heating the steel to a high temperature and then rapidly cooling it in oil or water to harden it. The steel is then tempered at a lower temperature to increase its toughness and reduce its brittleness.
D2/1.2379 steel is a popular tool steel used for making knives, dies, punches, and other cutting tools. It is known for its high wear resistance, toughness, and edge retention. The chemical composition of D2/1.2379 steel includes high levels of carbon, chromium, vanadium, and molybdenum, which give it its unique properties. While D2/1.2379 steel has its pros and cons, it is a versatile tool steel that can be used in a wide range of applications.
D2/1.2379 steel is often compared to other tool steels such as A2 steel, O1 steel, and S7 steel. While each steel has its own strengths and weaknesses, D2/1.2379 steel is generally known for its high wear resistance and toughness. A2 steel is known for its toughness and stability, while O1 steel is known for its ease of sharpening and edge retention. S7 steel is known for its shock resistance and toughness.
