UGIMA® 4542 +P930/H1150

UGIMA® 4542 +P930/H1150 introduction

UGIMA® 4542 is the first UGIMA® steel product from the family of improved machinability, precipitation hardened stainless steels. It is manufactured only by UGITECH.
Its properties are identical to those of UGI 4542 except for its machinability which is significantly better than that of UGI 4542:

UGIMA® 4542 has new technological advances bring significant advantages over grade 1.4542.

Productivity increases of 20 to 30% are obtained compared with grade UGI 4542.

This stainless steel is unique in that it not only offers excellent corrosion resistance, comparable to that of type 1.4301/1.4307 (304/304L) austenitic stainless steels, but it also offers a wide range of mechanical properties once treated.

Its performance - based on its metallurgical condition - means that it can meet demands for high levels of tensile strength as well as being suitable for applications that require high impact strength.

The microstructure is martensitic with some ferrite stringer. Depending on the metallurgical condition some retained austenite and copper precipitates can be part of the microstructure.
