Product Description

Alloy N (UNS N10003) is a nickel-base alloy that was invented at Oak Ridge National Laboratories as a container material for molten fluoride salts. It has good oxidation resistance to hot fluoride salts in the temperature range of 1300 to 1600°F (704 to 871°C).HASTELLOY N alloy has good oxidation resistance in air. It shows promise for continuous operations at temperatures up to 1800°F (982°C). Intermittent use at temperatures up to 1900°F (1038°C) may also be possible. No discernible oxidation could be measured for the alloy at temperatures up to 1200°F (649°C).HASTELLOY N alloy can be supplied, to order, in the forms of sheet, plate, and bar.

Blind flange is also called blind plate, and its correct name is flange cover. It is a flange without a hole in the middle, used to seal the pipe plug. There are many types of sealing surfaces, including flat surface, convex surface, concave-convex surface, tongue-and-groove surface, and ring connection surface.
