107WCr5KU Steel Grade: A Closer Look at Its Composition and Impressive Mechanical Properties

The 107WCr5KU steel grade is a high-carbon, high-chromium cold-work tool steel. It is commonly used in the manufacturing of cutting tools and dies, as it offers excellent wear resistance and hardness retention even under high-temperature conditions. Let’s take a closer look at its chemical composition and impressive mechanical properties.

Chemical Composition:
– Carbon (C): 1.00-1.10%
– Chromium (Cr): 0.40-0.60%
– Manganese (Mn): 0.20-0.40%
– Silicon (Si): 0.15-0.30%
– Tungsten (W): 2.00-2.70%
– Vanadium (V): 0.30-0.50%

Impressive Mechanical Properties:
1. Hardness: The 107WCr5KU steel grade exhibits excellent hardness, typically ranging from 60 to 64 HRC after heat treatment. This high hardness level allows it to maintain sharp cutting edges and resist deformation during use.

2. Wear Resistance: Due to its high carbon and chromium content, this steel grade offers exceptional wear resistance. It can withstand abrasive wear and maintain its cutting performance for extended periods, leading to longer tool life.

3. Toughness: Along with its high hardness, the 107WCr5KU steel grade also possesses good toughness. This means that it can absorb shocks and impacts without fracturing, maintaining its reliability in demanding applications.

4. Strength: This steel grade’s chemical composition, particularly the addition of tungsten, provides it with high strength. It can withstand high stress and resist deformation even under demanding working conditions.

5. Heat Resistance: The 107WCr5KU steel grade exhibits good heat resistance, allowing it to retain its hardness and strength even at high temperatures. This makes it suitable for use in high-speed machining and hot-working applications.

Overall, the 107WCr5KU steel grade is an excellent choice for applications requiring high wear resistance, hardness, toughness, and strength. Its composition and impressive mechanical properties make it a reliable option for cutting tools and dies that need to withstand demanding working conditions.
