The appearance of Zirconium is silver-greyish in color. While there are multiple reasons for using this metal, Zirconium 706 Fasteners are known for exhibiting high corrosion resistance behavior. And due to its effective corrosion resistance properties, it is not uncommon to see the use of various components such as piping, fittings, or even Zirconium 705 Fasteners across several applications, where the environments are known to have harsh conditions.

For the most part, the Zirconium 704 Fasteners exhibit fantastic resistance to media that contains acids such as hydrochloric acid, formic acid, sulfuric acid, as well as nitric acid. In particular, when the Astm B493 Zirconium 702 Fasteners has been exposed to conditions with hydrochloric acid, the rate of corrosion is less than 5mpy. This low rate of corrosion is applicable even when the Zirconium Socket Cap Screws have been exposed to hydrochloric acid or HCl at all concentrations & across various temperatures in excess of the boiling point.

The Zirconium Bolts are ideal in applications involving the nuclear power industry. Unlike other metals, suppliers recommend using the Zirconium Threaded Rod in the nuclear industry solely because of its inability to absorb neutrons.  And because the metal is superconductive at lower temperatures, the Zirconium 700 Fasteners is ideal for super magnets. Although the properties of this metal are abundant, there are some examples wherein the use of Uns R60702 Nuts is not recommended. For instance, in the presence of Ferric or cupric chlorides, the corrosion resistance properties of Zirconium Studs decrease due to the oxidization they cause.
