UGIMA® 4460 Cold Finished and Drawn
UGIMA® 4460 Cold Finished and Drawn introduction
UGIMA® 4460 is an improved machinability stainless steel manufactured only by UGITECH.
Its properties are identical to those of 1.4460, except for its machinability, which is quite exceptional.
UGIMA® 4460 brings a technological advance that provides significant advantages, whatever the machining conditions, the machine or the tooling used.
Productivity increases of 10% to 30% have been obtained over grade 1.4460, the current market standard
Mechanical properties measured for cold-finished product produced from a range of hot-rolled steels (not drawn)
We must first remember that the use of austeno-ferritic grades above 300°C is not recommended, owing to the formation of embrittling phases that reduce resilience and affect the corrosion resistance properties (alpha', chi, and sigma phases at higher temperatures).
The DUPLEX or AUSTENO-FERRITIC grades are, as their names imply, partly austenitic (non-magnetic) and partly ferritic (ferromagnetic) phases.
