UGI® 4542 +P1070/H1025
UGI® 4542 +P1070/H1025 introduction
UGI® 4542 is a PH (Precipitation Hardening) martensitic stainless steel used for parts requiring a combination of high strength, high toughness and good corrosion resistance.
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 re-tained austenite and copper precipitates can be part of the microstructure.
UGI® 4542 is a ferro-magnetic grade with properties that differ depending on its metallurgical condition and therefore, the heat treatment applied.
