CORROSION RESISTANT ALLOYS (ABOVE 13% CR)
Tenaris has established alliances with Sandvik and PCC Energy Group to assist the oil and gas industry in this particular segment. We commercialize both companies' seamless, stainless steel downhole production tubing and other high performance products.

Sandvik and PCC Energy Group manufacture CRA products according to the API 5CRA and ISO 13680 international standards. These CRA materials are needed when there is a combination of the following factors:

• Presence of C02

• Presence of H2S

• Low pH

• Chlorides

• High temperature
