1.2379,also known as D2,which is a high carbon and high chromium alloy tool steel with high hardness and wear resistance.It contains molybdenum and vanadium,which makes it extremely good in terms of wear resistance.After heat treatment,1.2379 get the features of strong hardenability and good stability of dimension,which is suitable for manufacture large and complex cold working mold require high wear resistance.

1.2080,corresponding to the AISI D3 steel of America,which is a high carbon and high chromium cold working mold steel with high hardness and high wear resistance.Compare with 1.2379,the wear resistance and compressive strength is slightly lower,but more cost-effective.

What is the carbon steel? Carbon steel is one of the most commonly used materials in engineering and manufacturing industries due to its versatility, strength, and cost-effectiveness. But what is carbon steel? In its simplest form, carbon steel is a type of steel where the primary alloying element is carbon. The amount of carbon in carbon steel plays a significant role in determining its properties such as strength, hardness, and ductility. The more carbon that is present, the harder and stronger the steel becomes, but it can also become less ductile and more brittle.

In this comprehensive guide, we will delve into the characteristics, types, and uses of carbon steel, and address the various factors that engineers need to consider when selecting this material for their projects.
