Salt bath nitriding using sulphur-activated, non-contaminating salts, especially suitable for ferrous metals.
SURSULF efficiently solves all wear, fatigue and seizure problems thanks to the exceptional nitriding power of the bath.
Treatment parameters :
The SURSULF bath temperature is between 540 and 570°C (1000 and 1060° F) and treatment time varies between 30 and 210 minutes.
Installed equipment is suitable for treatment of parts to diameter 1,300 mm (51 in), height 2,300 mm (90 in).
Schedule 3-hour thermal stress relieving at 590°C (1094° F) minimum before final machining.
Application examples :
GEARS, CAMSHAFTS, SLIDERS, JOURNALS, ENGINE LININGS, ROCKERS, RACKS, CUTTING TOOLS, CRANKSHAFTS, HYDRAULIC CYLINDERS, STUB SHAFTS, WHEEL HUBS, LINKAGES, UNIVERSAL JOINTS, HINGE PINS, ALUMINIUM ALLOY CASTING MOULDS, PISTONS, DISTRIBUTORS, etc.
