Molybdenum screws are high-temperature fasteners made from pure molybdenum or molybdenum alloys through cold heading, hot heading, or precision turning. The core advantages of molybdenum screws lie in maintaining high strength under high-temperature environments, low thermal expansion, and excellent creep resistance, while also resistant to acid and alkali corrosion with high machining precision. Main applications include vacuum heat treatment furnaces, hot shield connections in tungsten-molybdenum sintering furnaces, and bolts for hot isostatic pressing machines.
