Introduction to the hardness of zirconium rods
The hardness of zirconium rods is usually around 7.5HB, but the specific hardness value may vary depending on the specific composition and processing technology of the zirconium rod.
The hardness of Zr702 zirconium rod is 7.5HB, and although Zr705 zirconium rod is similar to Zr702 in corrosion resistance, Zr705 is better than Zr702 in mechanical properties. Although the specific hardness value is not directly given, it can be inferred that the hardness of Zr705 may also be slightly different.
In addition, the hardness of zirconium rods is also affected by the processing technology, such as heat treatment and cold processing, which will affect the hardness of zirconium rods. 12.
