R60704 zirconium rods belong to the zirconium-tin alloy family and are an important member of the industrial zirconium material family. Compared with industrial pure zirconium R60702, R60704, by adding tin (Sn) and appropriate amounts of iron + chromium (Fe + Cr), further enhances the material's strength while maintaining excellent corrosion resistance. This material is widely used in chemical equipment and high-temperature corrosive environments, and is a reliable choice recognized by many design institutes and end users.
Chemical composition and technical parameters
Our R60704 zirconium rods conform to ASTM B550 standards, with the following main chemical composition controls:
- Zirconium + Hafnium (Zr + Hf) content: ≥97.5%
- Tin (Sn): 1.0%～2.0%
- Iron + Chromium (Fe + Cr): 0.2%～0.4%
- Oxygen (O): ≤0.16%
- Carbon (C): ≤0.05%
- Nitrogen (N): ≤0.015%
- Hydrogen (H): ≤0.005%
In terms of mechanical properties, R60704 has a tensile strength of not less than 415MPa, a yield strength of not less than 240MPa, and an elongation of not less than 16%. Compared to R60702, its strength indicators are significantly improved, enabling it to adapt to applications with higher stress levels, while maintaining good ductility, thus balancing the requirements of processing and forming as well as reliability in use.
Application areas and performance advantages
The core advantage of R60704 zirconium rods lies in their excellent balance between corrosion resistance and strength. In strong acid media such as sulfuric acid, hydrochloric acid, and nitric acid, its corrosion resistance is comparable to that of pure zirconium; while under load-bearing conditions, R60704's superior mechanical properties provide additional safety. This material is widely used in chemical reactors, heat exchangers, pump and valve components, and other fields.
