RotoTec CoroResist 19300 metal powder

for corrosion-resistant coatings

RotoTec CoroResist 19300

Metal powder based on an austenitic CrNiMo steel. Good resistance to metallic sliding friction, lubricated. Corrosion resistant. For operating temperatures up to 450 °C. Machinable. Spray coatings are heterogeneous and microporous.

Technical data
Hardness [HV 30]: 250*
Grain size distribution [μm]: 38 - 125
Density [g/cm3]: 7.8

Applications
For flame spraying without melting of unalloyed, low-alloy and high-alloy steels and the corresponding cast steel grades.

Typical applications are
Pistons and valve stems, components from chemical plants and chemical machinery.

Processing instructions
Remove damaged material. Round off or chamfer edges. Clean spray areas, preheat to 50 - 150 °C and roughen. Spray on a layer of primer powder in the preheated state. Maintain spray coat temperature between 50 °C and 200 °C and apply up to the desired coat thickness. Do not exceed a layer thickness of 2 mm. Allow to cool in still air.

Spray gun: CastoDyn DS 8000
Primer powder: ProXon 21021

*The achievable hardness values depend on the selected spraying parameters, preheating temperatures, etc. No guarantee can therefore be given that the hardness values will be achieved.
