Molybdenum products are important in the missile industry, where it is used for high-temperature structural parts, such as nozzles, leading edges of control surfaces, support vanes, struts, reentry cones, heal-radiation shields, heat sinks, turbine wheels, and pumps.
Molybdenum products have also been useful in the nuclear, chemical, glass, and metallizing industries. Service temperatures, for molybdenum alloys in structural applications arc, are limited to a maximum of about 1650'C (3000'F). Pure molybdenum has good resistance to hydrochloric acid and is used for acid service in chemical process industries.
