Product Description

 

CPM 10V was a high vanadium tool steel.this steel optimized the vanadium content to provide superior wear resistance while maintaining toughness and fabrication characteristics comparable to D2 and M2. CPM 10V has become recognized world-wide and sets the standard for highly wear resistant industrial tooling. Its exceptional wear resistance and good toughness make it an excellent candidate to replace carbide and other highly wear resistant materials in cold work tooling applications, particularly where tool toughness is a problem or where cost effectiveness can be demonstrated. The CPM process produces very homogeneous, high quality steel characterized by superior dimensional stability, grindability, and toughness compared to steels produced by conventional processes.

Typical Applications:
Stamping or Forming Tools
Powder Compaction Tooling
Industrial Knives and Slitters
Plastic Mold Inserts
Wear Parts
Punches and Dies
Blanking and Piercing Dies
Woodworking Tools
Plastic Injection Barrels

Thermal Treatments:
Critical Temperature: 1540°F (840°C)
Forging: 2000-2100°F(1095-1150°) Do not forge below 1700°F (930°C). Slow Cool.
Annealing: Heat to 1600°F (870°C), hold 2 hours, slow cool no faster than 30°F (15°C) per hour to 1000°F (540°C), then furnace cool or cool in still air to room temperature.
Annealed Hardness: About BHN 255-277

Stress Relieving
Annealed Parts: Heat to 1100-1300°F (595-700°C), hold 2 hours, then furnace cool or cool in still air.
Hardened Parts: Heat to 30°F (15°C) below original tempering temperature, hold 2 hours, then furnace cool or cool in still air.
Straightening: Best done warm 400-800°F (200-430°C)

Hardening
Preheat: Heat to 1500-1550°F (815-845°C) Equalize. Second pre-heat stage at 1850-1900°F (1010-1040°C) suggested for vacuum or atmosphere hardening.
Austenitize: 1850-2150°F (1010-1175°C), hold time at temperature 30-45 minutes.
Quench: Air or positive pressure quench (2 bar minimum) to below 125°F (50°C), or salt or interrupted oil quench to about1000°F (540°C), then air cool to below 125°F (50°C). Salt bath treatment, if practical, will ensure maximum attainable toughness for a given hardening treatment. Vacuum or atmosphere quench rate through 1850-1300°F(1010-705°C) range is critical to achieve optimum heat treat response.
Temper: Double temper at 1000°F (540°C) minimum. 2 hours minimum each time. (See Table)
Size Change: +0.03/0.05%

Recommended Heat Treatment: For the best combination of toughness and wear resistance, austenitize CPM 10V at 2050°F (1120°C), hold 30-45 minutes, and quench. Temper 3 times at 1025°F (550°C).

Aim hardness: HRC 60.
Higher austenitizing temperatures can be used to obtain higher hardness, at a slight decrease in impact resistance. The lower austenitizingtemperatures provide the best impact toughness
