Welding and heat treatment of nickel alloys

Nickel is a silver-white metal that was first isolated in 1751 by the Swedish mineralogist Kronstadt. Ni was not made until 1775. From 1825 to 1826, Sweden began the industrial production of Ni, until the Ni refining into alloy steel, Ni industry has a rapid development. Because it has good mechanical strength and ductility, refractory high temperature resistance, and has high chemical stability, no oxidation in the air and other characteristics, it is a very important non-ferrous metal raw...
