| Corrosion properties | UGIMA® 4305 HM has excellent ability to withstand corrosion in many environments. Its corrosion resistance is typical of an austenitic steel and is similar to that of the 4305 / 303 in every respect. UGIMA® 4305 HM is pickled in the same way as 304 grade steel. Decontamination of steels with a high sulphur content is not recommended owing to the complexity and cost of this operation; however, if it is necessary, the recommended decontamination / passivation process is as follows: 1 volume 52% nitric acid (36° Baumé) 1 volume water ambient temperature short duration wash carefully when the process is completed The corrosion resistance of a stainless steel depends on many factors related to the composition of the corrosive atmosphere (chloride concentration, presence or absence of oxidising agents, temperature, pH, agitation or no agitation, and so on), as well as to the preparation of the material (surfaces free from metal particles, surface finish, such as hardening, polishing, and so on). Precautionary measures should be taken for certain tests such as the saline mist test (French standard NFX 41002): for example marking labels (that might cause corrosion run-outs and reduce the test resistance time) should not be used on the sample. | |
| General machinability | The performance of UGIMA® 4305 HM in machining is exceptionally good as a result of the optimisation of the inclusion population. This is true for very high speeds and severe cutting conditions, as a result of the UGIMA® process, but also for low speeds and less severe cutting conditions, because of the new improvements achieved through this latest development. UGIMA® 4305 HM is therefore particularly appropriate for screw machining, as its improved machinability is effective through an extensive range of cutting conditions and machining operations. Its performance is based on extremely good chip breakability, extended tool life and excellent surface finish. If you would like to use the grade to best advantage for your components and working environment, contact our Technical Service. | |
| Heat Treatment | The annealing treatment that gives UGIMA® 4305 HM its lowest properties includes heating to 1000 - 1100°C, followed by rapid air or water cooling. | |
| Hot forming | The forging of UGIMA® 4305 HM is not recommended. However, if this operation is indispensable, the material should be heated to 1175 - 1205° C, and the work should be finished at a temperature higher than 955°C | |

| Welding | Like all stainless steels with a high sulphur content, UGIMA® 4305 HM is very difficult to weld, due to the almost inevitable phenomenon of thermal weld cracking. This is particularly true in the case of welding without the use of filler material. If a weld is required, it is recommended that ER312 welding wire be used as the filler metal to minimise thermal cracking problems. Heat treatment must not be performed after welding with ER312 wire. | |
