GENERAL INFORMATION
Super austenitic stainless steel with a high content of molybdenum Mo and nitrogen N is used to work in oil and gas wells, with an aggressive environment and high concentrations of CO2, H2S and Chlorides.
MAIN DELIVERY CONDITIONS
The wire is supplied seamless, without welded joints, on metal coils in protective packaging for safe transportation.
The wire is supplied in length, the maximum winding on the drum is 30’000 feet or 9’145 meters.
