Exploring High Carbon, Chromium tool steel for cold work applications!

High Carbon and High Chromium tool steel HCHCR-D2 and HCHCR-D3! Excellent toughness and high hardness at elevated temperatures.

HCHCR-D2 and HCHCR-D3 are commonly used tool steel grades in the Indian steel industry. These grades are similar to the international standards AISI D2 and AISI D3, respectively.

HCHCR-D2 (or AISI D2) is a high-carbon, high-chromium tool steel. It contains approximately 1.5% carbon, 12% chromium, 0.8% molybdenum, 1% vanadium, and smaller amounts of other alloying elements. This composition contributes to its excellent wear resistance, high hardness, and good dimensional stability. HCHCR-D2 steel is known for its ability to retain its hardness and cutting performance even under high temperatures.
HCHCR-D3 (or AISI D3) is a high-carbon, high-chromium tool steel with added cobalt. It typically contains around 2.0% carbon, 12% chromium, 0.2% molybdenum, 0.5% vanadium, 1% cobalt, and smaller amounts of other elements. This composition gives HCHCR-D3 steel good hardness, wear resistance, and dimensional stability. It is particularly suitable for applications that require high wear resistance, such as blanking and forming dies.

Both HCHCR-D2 and HCHCR-D3 steels are primarily used in cold work applications.

They are commonly employed in the manufacturing of various cutting tools, such as punches, dies, slitters, and forming tools. These steels offer excellent strength, toughness, and wear resistance, allowing them to withstand the mechanical stresses encountered in cold work operations.

Heat treatment processes, such as quenching and tempering, are typically applied to HCHCR-D2 and HCHCR-D3 steels to achieve the desired hardness and toughness. These processes enhance the steel’s properties and ensure optimum performance in their respective applications.

In summary, HCHCR-D2 and HCHCR-D3 are popular tool steel grades in India, similar to the international standards AISI D2 and AISI D3. They are utilized in cold work applications, offering high hardness, wear resistance, and dimensional stability, making them suitable for various cutting tools and forming dies.
