Technical Information Tapping Guide coating properties and application precautions Titanium Nitride Proprietary TiN coating (hardness 2300 Vickers) offers Use with caution in non-ferrous materials such as (TiN) significantly improved wear life and thread finish, often at higher aluminium because of tendency to gall. tapping speeds, in a broad range of materials, especially steels, irons, and plastics. Golden colour. Titanium Carbonitride Proprietary TiCN coating (hardness 3000 Vickers) is harder, Use with caution in non-ferrous materials such as (TiCN) tougher, and more wear resistant than TiN under conditions of aluminium because of tendency to gall. TiAlN is a better moderate cutting temperatures. Like TiN, TiCN may be used at choice when used at extreme temperatures. higher cutting speeds in a broad range of materials, especially steels and irons. Blue-grey colour. Titanium Nitride + Proprietary coating (hardness 2300 Vickers) that combines the Effective in both ferrous and non-ferrous materials. Chromium Carbide wear resistance of smooth TiN coating with a lubricous top layer Carbon of chromium carbide carbon. Effective in stainless steel and non- (TiN + CrC/C) ferrous materials including aluminium and titanium. Ideal choice for 300 series stainless steels, wrought, and die cast aluminiums. Black/grey colour. Titanium Aluminium Nanolayer TiAlN coating (hardness 3300 Vickers) offers improved Use with caution in non-ferrous materials because of Nitride wear life and thread finish, especially in conditions where high tendency to gall. (TiAlN) temperatures can be generated. Use for PH stainless steels and nickel-based alloys like INCONEL®. Violet/grey colour. Chromium Nitride CrN is medium hard (hardness 1800 Vickers) and has a lower Ineffective in ferrous materials. (CrN) wear resistance than TiN, TiCN, and TiAlN. However, unlike these coatings, CrN does not gall when used in some non-ferrous work materials. Use for brass, bronze, zinc alloys, and magnesium alloys. Silver colour. Nitride Hardened case extends wear life in abrasive materials. Use for Avoid on taper pipe, fast spiral, and small diameter (MAXI #1) aluminium and other non-ferrous materials. (<#6) or fine pitch taps due to tendency for thread chipping. Oxide Helps prevent galling in ferrous (iron-based) materials. For free Has a tendency to cause galling in non-ferrous (SH-50) machining steel. Use for steels, stainless steels, and irons. materials such as aluminium. Nitride and Oxide Combines the benefits of nitride and oxide surface treatments.
