super duplex 2507 coiled tubing/capillary tubing

Super Duplex SAF 2507 is a really strong material with great corrosion resistance.

The fact that this is a stainless-steel material, the two attributes that make it different is its high thermal capacity and its low coefficient for thermal expansion.

Other than that, this material’s corrosion resistance and toughness cannot reduce what so ever is done.

From chloride stress, corrosion fatigue, erosion-corrosion, corrosion cracking, to general corrosion in acid, this material has high resistance. Apart from this, this material is known for its good mechanical strength and high weldability.
