Our Deep Well Series shows high strength with good ductility and fracture toughness.

PROPRIETARY GRADES FOR THE DEEPEST WELLS
Tenaris offers its Deep Well (DW) proprietary steel grades for oil and gas operations demanding very high strength materials with good ductility and fracture toughness. As depth increases a combination of higher pressures and temperatures defines the use of high strength materials.

As yield strength increases, the general trend of carbon steel is to become more brittle. Brittle materials may fail under loads, even those below minimum yield strength.

We have developed DW grades that achieve this trade-off in addition to high yield strength, good ductility and fracture toughness.
