UGIMA® 4057 Annealed
UGIMA® 4057 Annealed introduction
UGIMA® 4057 is a member of the UGIMA® family of improved machinability martensitic stainless steels. It is developed exclusively by Ugitech.
Its properties are identical to those of 1.4057, except for its machinability which is even better than that of 1.4057:
UGIMA® 4057’s new technological advances are extremely advantageous and a great improvement on 1.4057.
productivity increases of between 10% and 20% over grade 1.4057 have been obtained. Such increases are more noticeable in the case of monobloc carbide drilling or when a carbide-tipped toolbit is used.
In addition to excellent corrosion resistance, this stainless steel has the particular advantage of offering a wide range of mechanical properties in the processed condition. This grade also meets the requirements of EN10272 with respect to pressure vessels.
Its performance - depending on its metallurgical condition - ensures compliance with high mechanical strength require-ments and meets the demands of applications where substantial resilience is needed.
