Nascent Pipe & Tubes is one of the well-established dealer and stockiest of quality Nickel Alloy 201 (Bolts / Nuts), where annealing should be performed in a reducing atmosphere to retain bright finishes. These Nickel 201 Hex Head Bolts has been found that 0.25 % moisture in hydrogen chloride did not affect corrosion rate in both wet and dry gas at 400 Degree F (205 Degree C). Annealing of our Nickel 201 Hex Head Nuts for periods of 1 hour or more at temperatures above 1700 Degree F (925 Degree C) will result in hardness.

Heat treatment for these Nickel 201 Square Bolts, commonly called a dead – soft anneal, is used only in specialized applications such as burst diaphragms because of the low mechanical properties and coarse grain structure produced. Dry hydrogen and dissociated ammonia are preferred for our Nickel 201 Square Nuts, but less expensive atmospheres like partially burned natural gas will also provide adequate brightness.
