Technological properties
Property | ||
---|---|---|
Application areas | Usage limitations: cryogenic applications (insufficient toughness), applications requiring non-magnetic properties, high mechanical properties by thermal treatment | |
Cold Forming | Ugima® 4511 is easy to work using the conventional processes of cold forming: cold drawing, shaping, forming, cold heading, etc. Thanks to its moderate work-hardenability, Ugima® 4511 allows to limit the stresses on the tools (thus their wear) during cold working. | |
Corrosion properties | Pitting corrosion : We assessed this type of corrosion by testing the pitting potential: the higher its mV, the greater the pitting corrosion resistance; a neutral, slightly chlorinated pH environment (0.02 moles/litre of sodium chloride) of municipal drinking water was chosen (at 23°C). The following table gives the pitting potential values measured on samples from bars turned in the transverse direction: | |
General machinability | Compared to a standard 1.4511, UGIMA® 4511 provides significant productivity increases in bar turning, thanks to a slower tool wear and especially a better chip breakability for the same cutting conditions. Axial drilling and cross-cutting: The table below shows the cutting conditions that can be achieved to produce 1000 components without having to change any tool for each grade according to the operations and the tools used. | |
Heat Treatment | To restore ductility after cold deformation, Ugima® 4511 can be treated at a temperature between 750 and 850°C and air cooled. | |
Hot forming | Ugima® 4511 has excellent hot workability at all temperatures, due to its entirely ferritic structure. It can be hot formed by forging or rolling at between 800°C and 1150°C. The heating temperature must not exceed 1150°C to prevent excessive grain growth. | |
Other | Available products: Other options: contact the supplier | |
Welding | Thanks to its niobium stabilisation, UGIMA® 4511 can be welded in the same way as a standard 1.4511 by most arc welding processes (GMAW/GTAW, with or without filler metal, SMAW, plasma, etc.), by laser, resistance (spot or seam), friction or electron beam welding, etc. |
