VM 50 125 is an austenitic Corrosion Resistant Alloy nickel based. The main alloying elements are 54%Ni, 20%Cr and 9%Mo. VM50 125 is delivered in cold work condition. It can be hardened by drawing or pilgering.
VM 50 125 is recommended in very severe environments with CO2, H2S, chlorine and possibly presence of native sulfur. The VM 50 125 is designed for resistance to very high temperature. VM 50 125 can be used as
VM 50 125 has been tested at high temperatures for SCC with different levels of H2S and some native sulfur.
