UNS NO6625 a variety of corrosive media has excellent corrosion resistance of low-carbon nickel-chromium-molybdenum-niobium alloy. As the carbon content is low and stable after heat treatment, even at 650-900 ℃ high temperature insulation 50 hours later still not sensitized tendency. Availability status is annealed to soften its corrosive applications including wet environments, and used to obtain a temperature of -196 ~ 450 ℃ TÜV certified pressure vessel. Another minor adjustment of performance suitable for high temperature applications. By age hardening can improve mechanical properties.

UNS NO6625 Characteristics:
