UGIMA® 4021/UGI® 4021
UGIMA® 4021/UGI® 4021 introduction
In the treated state, a martensitic grade combining excellent mechanical properties with good corrosion resistance on suitably polished surfaces in moderately aggressive non-chlorinated environments. Good resistance in oxidizing atmosphere up to 600°C. UGIMA® grade produced according to an Ugitech process to significantly improve its machinability, up to diameter 115 mm.
