Vacuum Furnace Molybdenum Screw
Vacuum Furnace Molybdenum Screw
Molybdenum screws are high-performance refractory metal fasteners engineered for extreme operating conditions where conventional steel or nickel-based alloys fail. Manufactured from pure molybdenum or specialized molybdenum alloys, these screws maintain structural integrity, mechanical strength, and dimensional stability in high-temperature, high-vacuum, and corrosive environments.
