Pilot light burners and housings
An affordable yet high-quality alternative
The high temperatures and temperature changes in pilot-light systems quickly degrade the base material when using low-alloy or unalloyed steels. This often results in the system failing. The use of heat-resistant materials is not an option, as this makes the costs extremely high. Plus, the parts are difficult to produce and machine.
Free-cutting steel is a good alternative – a material that creates a low-cost design that is easy to produce in large series. But without surface treatment, this solution doesn’t meet the technical requirements.
With soft inchromizing (CM 1001), we add about 35% chromium to the iron on the surface. The free-cutting steel then achieves a temperature and oxidation resistance of 850°C, making for an unlimited service life.
