Common grades and ingredients

R60702: It is a high-purity Zirconium material, the main chemical components are Zirconium and a small amount of hafnium. Its impurity content is strictly controlled, and it has excellent corrosion resistance and processing performance. It is suitable for various corrosive environments, such as chemical industry, nuclear industry and other fields.

R60705: A certain amount of alloy elements such as niobium, iron, and chromium are added to zirconium. The addition of these elements improves the strength, hardness and high temperature resistance of the material, allowing it to be used at higher temperatures and pressures. It is often used in aerospace, navigation, high-temperature chemical industry and other fields that require high material performance.

Implementation standard ASTM B523/B523M-18 (2023): specifies the standard specifications for Zirconium and Zirconium alloy seamless and welded pipes, including requirements for pipe size, shape, tolerance, mechanical properties, chemical composition, etc., to ensure the quality and reliability of zirconium pipes in various applications.

ASTM B550/B550M-23: is the standard specification for zirconium and zirconium alloy bars and wires, covering the diameter, length, straightness, surface quality, mechanical properties and other technical indicators of bars and wires to meet the use requirements of zirconium bars and wires in different fields.

ASTM B551/B551M-12 (2021): defines the standard specifications for zirconium and zirconium alloy plates, sheets, and strips, and specifies thickness, width, length, flatness, surface roughness, chemical composition, mechanical properties, etc., providing a unified standard for the production and application of zirconium plates.

Performance characteristics Excellent corrosion resistance: American standard zirconium has strong corrosion resistance and shows good corrosion resistance stability in many corrosive media. For example, in strong acids such as concentrated sulfuric acid, hydrochloric acid, nitric acid and various salt solutions, the corrosion rate of zirconium is extremely low, and the integrity and performance of the material can be maintained for a long time. Therefore, it is widely used in corrosive environments in the chemical, petroleum, pharmaceutical and other industries.
