VM 100 SS is a high H2S corrosion resistant grade low alloy steel. Its sour service resistance has been designed and material is quality control tested per lot. It is in accordance with API 5CT Grade T95 Type 1 PSL 2 with restricted YS at the top of the grade. It has an 85% SMYS threshold level of resistance to sour environment.
VM 100 SS can be used as tubing or casing with effluent containing H2S from room to high temperatures. VM 100 SS is available up to 16" and with heavy wall up to 1 inch and more. Recommended use is with pCO2 below 2psi / 0.14bar.
VM 100 SS is an optimized 95ksi grade with restricted yield strength range and H2S resistance at 85% SMYS in NACE A test conditions.
