ASTM B551 Zirconium And Zircnoium Alloy Plate

1. Product introduction:Zirconium is superior to stainless steels, nickel alloys, and titanium in organic acids. This alloy is considered for these applications at high temperatures where its marked superiority results in a distinct economic advantage. Zirconium has poor resistance to concentrated sulfuric acid, hydrofluoric acid, concentrated phosphoric acid, ferric chloride, cupric chloride, wet chlorine, and other oxidizing chloride environments. Zirconium sheet also has a very high melting point, only melting at 1,855°C. As a result of this, a pure zirconium sheet remains solid when many other metals are fully liquid, and is ideal for use in very high-temperature environments.

Description

Production Introduction

No metal or alloy is resistant to corrosive attack in all chemical environments. Zirconium is no exception, but it does have excellent resistance to a wide variety of chemicals. Zirconium has outstanding resistance to hydrochloric acid, sulfuric acid, organic acids, and alkaline media such as sodium hydroxide. Its resistance to nitric acid is equaled only by noble metals such as tantalum.

The most common application areas for cast zirconium equipment are in hydrochloric acid, sulfuric acid, and hot organic acids. Zirconium shows excellent corrosion resistance to all concentrations of hydrochloric acid even at temperatures exceeding the normal boiling point. However, zirconium is not resistant to hydrochloric acid-containing oxidizing species such as cupric chloride, ferric chloride, or wet chlorine. Zr 702C is resistant to sulfuric acid concentrations up to 70 percent and Zr 705C is resistant to concentrations up to 55 percent to the normal boiling point of sulfuric acid. Poor resistance is obtained with higher concentrations, even at room temperature.
