VM 90 S is a H2S corrosion resistant grade low alloy steel. Its sour service resistance has been tested and verified. No further check is needed that allows shorter lead time. Its main characteristics are in accordance with API 5CT Grade R95 PSL2 and guarantee a very good threshold level of resistance to sour environment.
VM 90 S can be used as tubing or casing with effluent containing H2S from room to high temperatures. Recommended use is with pCO2 below 2psi / 0.14bar.
VM 90 S is a 90ksi grade guaranteed H2S resistant at 85% SMYS in NACE A test conditions.
