TiN (Titanium Nitride)
A physical vapor deposition (PVD) process of placing a thin coating of Titanium Nitride (TiN) 1 to 5 microns thick on working area of piercing punches to provide:

• Increased wearlife
• Rc 80-85 surface hardness
• Low coefficient of friction-50% of steel on steel
• Resistance to galling
• No chipping or peeling

Available as a special surface treatment on piercing point on Moly type tool steel punches and die buttons.

Ask for TiN coating piercing surfaces on M series high speed steels and CPM grades of tool steel.

Titanium Carbonitride(TiCN)
A physical vapor deposition (PVD) process of placing a thin coating 1 to 5 microns thick of Titanium Carbonitride (TiCN) on working area of Porter punches to provide:

• Rc 90 surface hardness
• More wear resistance and toughness than TiN coating
• 40% coefficient of friction of steel on steel
• No chipping of peeling

For high performance use TiCN special surface treatment on Porter punches and die buttons

Request TiCN coated punch points on M series high speed steel and CPM grades of tool steel.

CrN (Chromium Nitride)
A physical vapor deposition (PVD) process of placing a thin coating of Chromium Nitride (CrN) 1 to 5 microns thick on piercing punches for specialized applications to provide:

• Thermal stability up to 1300· F
• Rc 78 surface hardness
• 60% coefficient of friction of steel to steel
• Superior wearlife
• Reduced galling

For specialized applications use CrN surface treatment on Porter punches and die buttons.

Request CrN coated punch points on M series high speed steel and CPM grade tool steels.
