Corrosion properties | UGIMA® 4570 has excellent ability to withstand corrosion in many environments. Its corrosion resistance is typical of an austenitic steel and is slightly better than that of 1.4305 (303). In addition, as with all high sulphur steels, special care must be taken when using UGIMA® 4570 in acid or chloride environments that are liable to pitting and crevice corrosion; it should not be used where components are shaped in such a way as to have areas where corrosive products might collect and corrode. UGIMA® 4570 is pickled in the same way as 303 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 | |
General machinability | The performance of UGIMA® 4570 in machining is exceptionally good, as a result of the sulphur + copper UGIMA® synergy. This is true for very high speed or severe cutting conditions, as a result of the UGIMA® process, but the addition of copper reduces sensitivity to cold hardening by machining and is beneficial for machining operations such as knurling, deep drilling (>4xD) and threading and tapping by rolling. The cutting conditions shown in the tables on the right side of the material page are those which we established in the trial phase of the development of UGIMA® 4570. If you would like to use the grade to best advantage for your components and working environment, contact our Technical Service. Tools See the tables on the right side of the material page. Drilling Lubricant Lubricants with high-pressure additives are recommended. Tools Warning: Although the cutting conditions indicated in this data sheet are derived from machining tests carried out in our laboratories and on our customers' premises, they must be adapted to suit the machine, tools and cutting lubricant used. Under no circumstances can UGITECH be held responsible for any damage that may occur through the use of the cutting parameter values listed above. | |
Hot forming | Forging UGIMA® 4570 should not be forged. 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® 4570 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. |
