Molybdenum Threaded Bar

The molybdenum threaded bar, also known as a molybdenum threaded rod or stud, is designed for high-temperature and vacuum environments where conventional steel fasteners cannot maintain strength or dimensional stability.

With its high melting point (2620°C), low thermal expansion, and excellent creep resistance, molybdenum threaded bars are widely used as structural fasteners and load-bearing connectors in thermal processing equipment.

Key Advantages

• Outstanding mechanical strength at elevated temperatures

• Low creep and minimal deformation under long-term thermal load

• Low vapor pressure, suitable for vacuum environments

• Excellent dimensional stability during thermal cycling

• Reliable performance where stainless steel fasteners fail

Typical Applications

• Vacuum furnace heating chambers

• Molybdenum heat shields and insulation assemblies

• High-temperature fixtures and racks

• Crystal growth furnace structures

• Sintering, brazing, and heat treatment equipment
