Technological properties

|---|---|---|
| Application areas | Watchmaking, Pharmaceuticals | |
| Cold Forming | Wire drawing – Shaping : The 4435 IRH grade has good cold forming capability. Its high cold work hardening compared with non-austenitic grades induces the use of appropriate tools. Cold working can make the grade very slightly magnetisable through the formation of strain-induced martensite. | |
| Corrosion properties | Uniform corrosion: Its higher molybdenum content provides it, in reducing mineral acids, with better uniform corrosion resistance than the conventional austenitics 1.4307 (304L) and 1.4404 (316L). | |
| General machinability | Thanks to control of its inclusion population and microstructure, UGI 4435 IRH can retain a satisfactory machinability level while ensuring optimal polishability for the grade. | |
| Hot forming | Forging: The grade can be hot-worked at between 900°C and 1250°C and then cooled rapidly, in water or air. Hot forming is generally followed by a solution annealing or quenching (see recommendations in the corresponding section). | |
| Other | Available products: Other possible options. Please consult the supplier. | |
| Surface Treatment | ||
| Welding | UGI 4435 IRH can be resistance welded (spot or seam welding) by any type of arc process (MIG, TIG, submerged arc, covered electrode), by laser, electron beam, etc. UGI 4435 IRH is balanced to be on the boundary of primary ferritic solidification in order to ensure a minimum of residual ferrite in the welding region while limiting its risk of crack formation at high temperature during arc welding. In laser welding, the risk of crack formation at high temperature is greater than with arc welding, and the welding parameters should be adjusted as well as possible on a case by case basis to limit this risk. Where a filler wire is used to weld UGI 4435 IRH to itself, preferably choose an ER316L(Si) – 1.4430 wire. | |
