Geegraf SST
Tanged Stainless Steel Reinforced Graphite Sheet

A graphite laminate material mechanically bonded and available in one metre square sheets or cut gaskets. The material comprises two outer layers of graphite foil with a central tanged stainless steel core 0.1mm thick. The layers are mechanically pressed together in-house with a laminating technique that does not delaminate during punching, storage and use.

• Minimum 99% purity graphite foil
• Thickness range 1.0mm to 4.0mm
• Mechanically bonded laminate. No adhesive used
• Optimum material for thermal cycling applications and where vibration is a problem
• Withstands high compressive stresses
• Greater recovery characteristics than flat metal reinforcement
• Improved blow-out resistance
• Difficult to cut by traditional methods, best results obtained by abrasive water-jet cuttingfor a smooth safe edge finish
• Maximum service temperature 500 Deg C in oxidising conditions
• Maximum service temperature 750 Deg C in inert and reducing conditions
• Maximum service pressure 200 Bar
• Can be used at cryogenic temperatures
• Compressibility 30 to 35%
• Recovery 15 to 20%

AVAILABILITY

Large diameter gaskets can be Water Jet cut in segments with dovetail joints.
