Product Description

 

CPM 15V is intended for applications requiring exceptional wear resistance. It has more vanadium carbides in its microstructure than CPM 10V and provides more wear resistance and longer tool life in those applications where 10V has proven to be successful. CPM 15V also offers an alternative to solid carbide where carbide fails by fracture or where intricate tool design makes carbide difficult or risky to fabricate.

Typical Applications:
Powder Compaction Tooling: Dies, Core Rods
Plastic Processing Equipment: Barrel Liners, Screw Tips
Industrial Knives: Granulator Blades, Slitter Knives
Dies/Punches for Cold Work: Forming, Extrusion, Drawing, and Piercing Woodworking Tools Ceramic Dies Wear Parts

Thermal Treatments:
Critical Temperature: 1540°F (838°C)
Forging: 2000-2100°F (1095-1150°C) 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 tem perature.
Annealed Hardness: About BHN 255-277

Stress Relieving 
Annealed Parts: Heat to 1100-1300°F (595-705°C), hold 2 hours, then furnace cool or cool in still air.
Hardened Parts: Heat to 25-50°F (15-30°C) below original tempering temperature, hold 2 hours, then furnace coolor cool in still air. Hardening Preheat: Heat to 1500-1550°F (815-845°C) Equalize. Asecond pre-heat stage at 1850-1900°F (1010-1040°C) is suggested for vacuum or atmosphere hardening.

Austenitize: 
1950-2150°F (1065-1175°C), hold time at temperature 20-30 minutes.

Quench: 
Air or positive pressure quench (2 bar minimum) to below 125°F (50°C), or salt or interrupted oil quench to about 1000°F (540°C), then air cool to below 125°F (50°C). Salt bath treatment, if practical, will ensure the maximum attainable toughness for a given hardening treatment.

Temper: 
Two times at 1000°F (540°C), 2 hrs. minimum each time. Temper three times for hardening tempera tures over 2100°F (1150°C). See Table for data.

Size Change: +0.04/0.05%

Recommended Heat Treatment:
For maximum wear resistance, austenitize at 2150°F (1175°C), hold 10 minutes, and quench. Temper 3 times at 1025°F (550°C).

Aim hardness: HRC 61-63
