VM 80 13ET is a martensitic stainless steel grade suitable for sweet corrosion environments (CO2) under which VM 80 ET or VM 50 ET would suffer localized corrosion.

Manufactured in accordance with latest edition of API 5CT and ISO 11960 – PSL-2 specifications (group 2 – L80) this material is suitable for Expandable application with Expansion Ratios (ER) up to 18%.

APPLICATIONS

​I​​ts primary applications are casing and liner extensions or zonal isolation with temporary exposure to production fluids. It will be used in CO2 corrosive well service environment (with temperatures down to -60°C) and where expansion ratios are not greater than 18 %.

​​It has limited SSC resistance and post expansion application will depend of CO2, temperature, pH and chlorides content.
