UGIMA® 4570 Cold Drawn Bar
UGIMA® 4570 Cold Drawn Bar introduction
UGIMA® 4570 is an improved machinability stainless steel manufactured only by UGITECH. Its properties are identical to those of 303, except for its machinability, which is even better.
The SULPHUR + COPPER + UGIMA® Process synergy achieves previously unimaginable, but now unrivalled machining performances: cutting speed up to 750 m/min during turning with a coated carbide insert.
Similarly, this synergy provides improved chip breakability and tool life and increases productivity by up to 70% over 1.4305 (303) and 20% over UGIMA® 4305.
The addition of copper reduces sensitivity to cold work-hardening compared with 1.4305 and improves machining operations such as knurling, deep drilling, threading and tapping by rolling, as well as bending and crimping (door and cupboard handles).
Austenitic, therefore non-magnetic grade after annealing at 1000/1100°C (magnetic permeability µ
