Parts treated with SURSULF® salt bath nitriding effectively resist seizure.
The micro-layer inhibits the formation of frictional welding points and helps the retention of lubricants and assists the running-in of components.
The hard, yet ductile surface layers make SURSULF® treated parts compatible with mating surfaces without surface cracking or exfoliation.
Iron nitrides (primarily Ɛ-Epsilon type) and precipitated alloying elements form a compound layer on the surface of SURSULF® treated components significantly improving their wear resistance.
SURSULF® also produces substantial improvements in fatigue resistance delaying the formation of subsurface fatigue failiures such as pitting and flaking.
Compliant with all known nitrocarburizing standards – SAE Aerospace Material Specification 2753C.
Treating ferrous materials (steel, cast iron, stainless steel and Inconel alloys) at temperatures typically between 540°C and 580°C and treatment times between 30 and 210 minutes. Precautions: Schedule 3-hour thermal stress relieving at 590°C (1094° F) minimum before final machining.
TSUK is home to the largest nitrocarburising baths in the UK, we can treat parts up to 1 metre in diameter and 3.2 metres in length.
