What Is CPM 10V Steel?
CPM 10V® is a powder metallurgy tool steel known for excellent wear resistance and high toughness. Its fine grain size and small carbides enhance toughness. With high vanadium carbide content, it outperforms steels like D2 and D7 in wear resistance. Used in cold-working tools, it offers better edge retention and toughness compared to CPM-154 and S30V.
While CPM 10V provides high toughness, it is more challenging to machine than lower alloy steels due to its hardness. It can be nitrided, steam tempered, or coated with titanium nitride (TiN). When using CVD TiN, careful vacuum hardening is required.

CPM 10V Steel Heat Treatment
We focus on providing tailored heat treatment solutions to enhance the performance of CPM 10V steel. We work closely with clients to meet specific heat treatment needs, ensuring that every batch of steel is treated to achieve the best results for its intended application.
Annealing
To soften CPM 10V and improve machinability, heat the steel to 1600°F (870°C) and hold for 2 hours. After soaking, cool the steel slowly at a rate of 30°F (15°C) per hour until it reaches 1000°F (540°C), then allow it to cool in air or a furnace. This process results in a hardness of 255-277 BHN.
Hardening
Preheating
Heat the steel to 1500-1550°F (816-845°C) and allow it to equalize. For vacuum or atmosphere hardening, a second preheat stage at 1850-1900°F (1010-1040°C) is recommended.
Austenitizing
Heat rapidly from the preheat stage to the high heat for austenitizing.
- For optimum wear resistance, soak the steel for 5 to 15 minutes at 2150°F (1177°C).
- For a balance of wear resistance and toughness, soak for 15 to 30 minutes at 2050°F (1121°C).
- For maximum toughness and minimal distortion, soak for 30 to 60 minutes at 1975°F (1080°C) in a furnace or 1950°F (1066°C) in a salt bath.
Quenching
After austenitizing, CPM 10V should be quenched using air, pressurized gas, warm oil, or salt. For sections less than 3 inches thick, air cooling is sufficient. For thicker sections, faster quenching is required to achieve maximum hardness.
Tempering
After hardening, CPM 10V should be tempered to reduce brittleness and improve toughness. The standard tempering temperature is between 400-500°F (200-260°C). Tempering at these temperatures provides a good balance of hardness and toughness.
Straightening
If needed, straightening of CPM 10V should be done at a warm temperature range of 400-800°F (200-430°C) to avoid distortion during the process.
CPM 10V Steel Applications
Here are some specific applications of CPM 10V steel:
- Circular Saw Blades – Used in woodworking and metal cutting due to its excellent wear resistance.
- Cold Heading Dies – Employed in the production of fasteners and bolts where high toughness and resistance to wear are needed.
- Punches and Dies – Used for high-volume stamping and punching operations in automotive and metalworking industries.
- Milling Cutters – Utilized in precision machining of hard materials, where edge retention is crucial.
- Slitting Blades – Commonly used in the paper, film, and plastic industries to cut thin materials with high wear resistance.
- Taps and Drills – Used for making holes and threads in hard materials, where the combination of hardness and toughness is critical.
