MACHINING & TREATMENTS
We can offer componentry engineering for valves treated with surface hardenings such as salt bath nitridings, plasma-ion-nitridings and innovative hardenings (i.e. Kolsterising®). All these treatments increase the surface hardness with full retention of corrosion resistance. These surface hardenings can be very different from each others as far as costs and performances are concerned; for this reason it is really important that the Client previously defines its main aim inside the plant engineering use.
