| Application areas | UGI® 4313 is intended for the following applications (non-exhaustive list): | |
| Cold Forming | Wire drawing – Shaping: UGI® 4313 is suitable for cold working by conventional methods. | |
| Corrosion properties | Localized pitting corrosion: The resistance to localized pitting corrosion largely depends on the composition of the grade; calculation of the PREN pitting index (=%Cr + 3.3x%Mo +16x%N) gives us an indication of the pitting corrosion resistance. With a calculated average PREN of 15, UGI® 4313 has a better corrosion resistance than that of the AISI 420 series (1.4034; average calculated PREN of 13.5); but it remains less satisfactory than that of the AISI 431 series (1.4057; average calculated PREN of 17). | |
| General machinability | UGI® 4313 can be machined both in annealed condition (A) and in quenched and tempered conditions (QT). The annealed condition, due to its low mechanical properties, is more subject to chip sticking to the tools, which could accelerate tool wear and adversely affect post-machining surface conditions. The quenched and tempered conditions (QT) cause tool wear that is all the faster when they have high mechanical properties. Accordingly, the QT700 condition has the best machinability of the 4 available conditions. | |
| Heat Treatment | Annealing: Annealing between 600°C and 650°C with cooling in air or in furnace, to be performed after martensitic transformation. Quenching: Quenching should be performed maintaining a temperature in a range between 900°C and 1150°C followed by cooling in air or in oil. Tempering : The choice of the post-quenching tempering temperature depends on the required mechanical properties. The temperatures recommended by EN 10088-3 are: | |
| Hot forming | Heating to between 1150°C and 1200°C is recommended. Hot working (forging) of UGI® 4313 should preferably be performed in the temperature range between 1200°C and 900°C and be followed by air cooling. The behaviour of the UGI® 4313 grade during forging is similar to that of a 1.4301 type austenitic grade. After hot working, a complete heat treatment, consisting of austenitizing and quenching and then tempering, is recommended. | |

| Welding | UGI® 4313 can be welded by arc welding processes (GMAW, GTAW, SMAW, etc.) and by most other processes (spot, seam, laser, etc.). Thanks to its low carbon content and the nickel that it contains, UGI® 4313 is easier to weld than most martensitic stainless steels. | |
