Products Description
ASTM B493 Zirconium 702 Round Bars is a high-performance alloy material consisting of zirconium as the main element. Zirconium alloy has excellent mechanical properties, corrosion resistance and thermal stability, so it is widely used in aerospace, shipbuilding, chemical industry, nuclear industry and other fields.
Zr702C zirconium alloy has excellent mechanical properties. The alloy has high strength and good toughness, and can withstand the stress under high pressure, high temperature and heavy load conditions. This makes it an ideal material for the aerospace sector, where it can be used to manufacture engine parts, aircraft structures and spacecraft housings, among others.
Zr702C zirconium alloy has excellent corrosion resistance. Zirconium alloy has good corrosion resistance and can resist the erosion of various corrosive media such as acid and alkali media, seawater and oxide. Therefore, it is widely used in the chemical industry, for the manufacture of reactors, heat exchangers, storage tanks and other equipment, to ensure the long-term stable operation of equipment.
Main Features
1. Mechanical properties: Zr702C zirconium alloy has high strength and hardness, with good tensile strength and yield strength. It also has good ductility and toughness, and can maintain good mechanical properties at high temperatures.
2. Corrosion resistance: Zr702C zirconium alloy has excellent corrosion resistance, especially for acid, alkali, salt and other chemical media with high corrosion resistance. It can work stably in acidic, alkaline and high temperature environments for a long time and is not susceptible to corrosion and oxidation.
