VM 28 110

VM 28 110.png

VM 28 110 is an aus​tenitic Corrosion Resistant Alloy. The main alloying elements are Ni, Cr and Mo. VM 28 110 is delivered in cold work condition. It can be hardened by drawing or pilgering.

​APPLICATIONS

VM 28 110 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 28 110 can be used as tubing or casing.

​PERFORMANCES

VM 28 110 has been tested from room to high temperature for SCC with different levels of H2S.​
