Temperature resistant

The stable zinc-iron alloys formed by the sherardising are inseparably bound to the base material and can be used at high temperatures without the zinc diffusing into the steel. This prevents any liquid metal embrittlement.

The coating is temperature resistant to temperatures in excess of 600°C. The zinc-iron alloy does not melt but will burn at temperatures of approximately 1000°C. Other coatings that contain zinc cannot be used at these temperatures.

Sherardising is ideal for ensuring that connecting components in engine rooms and exhaust systems are protected from corrosion at high temperatures. Sherardised valves and flange connections, for example, in the offshore, oil and gas industries are used at operating temperatures of more than 400°C.
