Description

SEACOL-760 provides superior pitting resistance as a result of an addition of tungsten to its chemistry, which also contributes to the alloy’s strength. This super duplex grade contains 25% chromium and 7% nickel in addition to a small percentage of copper to enhance its general corrosion resistance. SEACOL-760 has a Critical Pitting Temperature exceeding 50°C and is listed in NACE MR0175 for sour service applications.
