Description
Fields of application
Structural materials for the core of water-cooled nuclear reactors such as fuel jackets, pressure tubes, supports and tunnel tubes, etc., chemical and pharmaceutical plants as well as other industries with hydrochloric, nitric, sulphuric and acetic acids, alkalis and salts, electro-vacuum and light bulbs as non-dissipative degassing agents (degassing materials)
Products Description
Zirconium (Zr) alloys are composed of more than 95% zirconium and less than 2% tin, niobium, iron, chromium, nickel and other metals to improve mechanical properties and corrosion resistance. Zirconium alloy has good corrosion resistance, especially in high-temperature and high-pressure steam and water at 300 to 400 ℃, moderate mechanical properties, the atom's thermal neutron absorption cross-section is low, in addition, zirconium is also resistant to a variety of acids, alkalis and corrosion. Salt, with oxygen, nitrogen and other gases have a strong affinity, has been used in water-cooled nuclear reactors and corrosion-resistant parts and pharmaceutical machinery parts. In addition, it is also used in pharmaceutical, heating, water supply systems, paper and pulp industries.
