TZM alloy rods and ZHM alloy rods are two different alloy materials, and they have some differences in composition, properties and applications. Here are the main differences between them:
Composition: TZM alloy rods are mainly composed of molybdenum (Mo), titanium (Ti) and zirconium (Zr), among which molybdenum has the highest content. The ZHM alloy rod is composed of three elements: zirconium (Zr), hafnium (Hf) and molybdenum (Mo), and the content of zirconium and hafnium is relatively high.
Strength and hardness: Due to the difference in composition, TZM alloy rods are relatively high in strength and hardness, and have excellent mechanical properties. The ZHM alloy rod has lower strength and hardness, and is relatively soft.
High temperature resistance: Both TZM alloy rods and ZHM alloy rods have good high temperature resistance and can maintain good stability in high temperature environments. However, due to differences in composition, their high temperature performance may vary.
Corrosion resistance: Both TZM alloy rods and ZHM alloy rods have good corrosion resistance and can show high stability in many corrosive media. Specific corrosion resistance may be affected by composition and environment.
Application fields: TZM alloy rods are often used in high-temperature structural parts and components in aerospace, nuclear energy, chemical and other fields. ZHM alloy rods are commonly used in corrosion-resistant structural parts and parts in nuclear industry, chemical industry and other fields.
