Technological properties

Application areas | Watchmaking,Pharmaceuticals | |
Cold Forming | Wire drawing – Shaping : UGIMA® 4435 ICH 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. Bending – Forming: Good bending and forming capability | |
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). Pitting corrosion and crevice corrosion: It has very good corrosion resistance behaviour for a great majority of natural exposures (rural, urban and industrial). This grade, with high molybdenum content, offers among the best pitting and crevice corrosion resistance of the austenitic family. Its very good corrosion resistance behaviour means it easily complies with the EN1811 standard relating to nickel release. Intergranular corrosion: Due to its low carbon content, this grade resists intergranular corrosion after welding and after sensitizing heat treatment as specified in the standards (ASTM A262-75 Practice E; DIN EN ISO 3651-2). | |
General machinability | UGIMA® 4435 ICH undergoes the UGIMA® process for control of its oxide inclusion population, which provides it with an optimal machinability level for a 1.4435 steel without detracting from its other properties (corrosion resistance, weldability, etc.). Accordingly, the machining productivity of UGIMA® 4435 ICH can be increased by 10% to 15% by comparison with a standard 1.4435 steel. This effect is optimal when this grade is machined on machines and with tools enabling high cutting conditions to be achieved (modern machines and coated carbide tools). | |
Heat Treatment | Solution treatment (solution annealing): The solution annealing treatment can ensure optimal corrosion resistance properties. It should be performed at a temperature ranging between 1050°C and 1120°C and followed by rapid cooling in water or air (for products of small cross section). | |
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 us. | |
Welding | UGIMA® 4435 ICH 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. UGIMA® 4435 ICH 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 UGIMA® 4435 ICH to itself, preferably choose an ER316L(Si) – 1.4430 wire. The protection gases in arc welding should preferably be: No preheating or post-welding heat treatment is required. Interpass temperatures not exceeding 150°C should be complied with. |
