| Corrosion properties | The corrosion resistance properties of Ugima® 4460 in phosphoric and chloride environments are excellent. They are considerably higher than those of 316 steel in environments liable to cause pitting and crevice or stress corrosion. The table below shows an example of a scale of performance in different manufacturing environments: | |
| General machinability | The two-phase structure of these steels, each phase of which performs differently during machining, makes them more difficult to machine than austenitic stainless steels. They put a great strain on the tools (risk of vibrations, coating chipping) if they are not machined under optimum cutting conditions and if the tools used are not of the correct quality. Unlike austenitic stainless steels, they require the use of coated carbine inserts and low cutting speeds. The performance of UGIMA® 4460 in machining is exceptionally good as a result of the optimisation of the inclusion population. | |
| Heat Treatment | 1.4460 steel is used in annealed condition at 1030/1100°C and is OIL or WATER cooled. The heat treatment allows users to: | |
| Hot forming | The forgeability of Ugima® 4460 is not as good as that of the current 1.4307/1.4404 austenitic steels. A few practical rules: | |
| Other | Available products: Contact the supplier for any not listed. | |
| Welding | The percentage of ferrite in the molten areas of Ugima® 4460 is higher when the composition of the filler metal is identical to that of the base metal. This should be taken into account when the optimum composition of the filler metal is determined. In addition, the areas affected by the heat are also liable to contain more ferrite than the base metal. To minimize this difference, linear energy welding is recommended to reduce cooling times. However, only energy that does not cause phase formation should be used. There is also a linear energy welding area where the two above-mentioned risks are lower. The thicker the components to be welded, the higher the energy in this area (i.e. rapid weld cooling). It is not advisable to preheat components prior to welding. Components should not be heat treated after welding, but the annealing treatment described in the "Heat treatment" section may be carried out, if necessary. In the case of an MIG weld, Ni-based fillers such as those made of Ni 6660 could be used to ensure ductility and corrosion resistance in the molten area. | |
