| Corrosion properties | The UGI® PHYNOX® is not attacked by the organic acids. It resists the salt spray perfectly and its behavior with the mineral acids is definitely higher than that of the best stainless steels In addition, its perfect passivity in con-tact with human tissues, explains why UGI PHYNOX has been used for more than twenty five years in surgical implants. Examples of corrosion resistance: | |
| General machinability | The high mechanical properties in the as drawn condition and the ability of cold hardening during machining, need to take particular precautions for machining: Cutting fluid with high performances of cooling and lubrication | |
| Heat Treatment | 520°C / 3 hours – Air cooled: The heat treatment is performed after cold forming or machining without any deformation of the treated part. This treatment must be realized preferably in a vacuum furnace(10-5 Torr) or under protective atmos-phere (Argon) Processing in open air doesn’t affect the mechanical properties of the material, but alters its aspect. The influence of the treatment on annealed material is negligible but become very important on cold drawn products. Cleaning of parts 3 methods for removing the lubricating film and pickling after heat treatment Immersion 15 to 20 minutes Rinsing hot or cold water & drying Immersion 2 to 3 minutes Rinsing hot or cold water & drying Nitric passivation (40%) at room temp Rinsing hot or cold water | |
| Other | Available in wire (coil form) and in straightened ground bars (minimum diameter: 1 mm) Annealed condition: ø 0,60 mm up to 18 mm Hard condition : ø 0,012 mm up to 15 mm Other options: contact the supplier | |
| Surface Treatment | Pickling and polishing: Apart from mechanical descaling, the oxyde film formed during heating in air can be removed by immersing the parts in a boiling aqueous solution containing 5% hydrofluoric acid and 12% nitric acid. UGI® PHYNOX® can be electro chemically polished with products used for dental alloys cobalt basis | |
| Welding | UGI® PHYNOX® can be readily welded: resistance spot welding, electron beam welding, laser, argon arc welding. It can also be brazed. However, since age hardening can only obtained in cold worked area, this must be taken into account by placing the weld or braze joint in positions where it is not heavily loaded or by using a discontinu-ous joint | |
