VM 825 110 is an austenitic Corrosion Resistant Alloy. The main alloying elements are Ni, Cr and Mo. VM 825 110 is delivered in cold work condition. It can be hardened by drawing or pilgering.
VM 825 110 is recommended when pCO2 is above 2psi / 0.14bar, high temperature up to 450°F / 232°C and presence of chlorine. It resists to H2S partial pressure of more than 500psi – 34bar. Partial pressure H2S acceptable is governed by temperature.
VM 825 110 can be used as tubing or casing.
VM 825 110 has been tested from room to high temperature for SCC with different levels of H2S.
