Tenaris provides 13% Chromium grades and Corrosion Resistant Alloys (CRA) for oil and gas operations in highly corrosive environments where carbon pipe cannot be used.

PROPRIETARY STEEL GRADES FOR SEVERE CORROSIVE ENVIRONMENTS
In most conditions when the partial pressure of CO2 is above 30psi, carbon steels present high corrosion rates. Steel grades alloyed with high contents of Chromium (Cr), Molybdenum (Mo) and Nickel (Ni) are able to effectively resist corrosion.

We manufacture 13% Chromium tubular products in our mills. We supply Corrosion Resistant Alloys through our alliances with Sandvik and PCC Energy Group.

The development of ultra deep gas wells and enhanced recovery of oil and gas implies more aggresive environment, with higher downhole temperatures and corrosive gases.

13% CHROMIUM AND SUPER 13% CHROMIUM GRADES
Our group of 13%Cr alloys are martensitic stainless steels suitable for applications involving CO2 rich environments. 13CrS can be used in mild sour conditions. 13CrM and 13CrS have better performance with regards to corrosion resistance and excellent toughness.
