• Refractory Metals: Niobium, Molybdenum and Rhenium

    More molybdenum is consumed annually than any other refractory metal. Molybdenum ingots, produced by melting of P/M electrodes, are extruded, rolled into sheet and rod, and subsequently drawn to other mill product shapes, such as wire and tubing. These materials can then be stamped into simple shapes. Molybdenum is also machined with ordinary tools and can be gas tungsten arc and electron .

  • Molybdenum Disulfide (MoS2) Coating Services | Metal Coatings

    Moly coating is a combination of molybdenum disulfide lubricant and high performance resins. Molybdenum Disulfide coatings are thermally cured and thoroughly bonded to the base metal of the coated part. Uses for molybdenum disulfide coatings include appliions that require a lubricant that is more unreactive when in use, and remains sturdy. We offer Molykote coatings, Everlube coatings, .

    Corrosion Resistant Metals Home ... (6Mo) alloys are superaustenitic stainless steels which contain at least 6% molybdenum and have a PREN of at least 40. Alloy 6HN (UNS N08367) contains 6 weight percent more nickel (Ni) than alloy 254 (UNS S31254). This increase in nickel content gives 6HN added stability with respect to formation of undesirable intermetallic phases. Alloy 6HN has been found ...

  • Welding of Reactive and Refractory Metals

    Reactive metals have a strong affinity for oxygen and nitrogen at elevated temperatures and when combined form very stable compounds. At lower temperatures they are highly resistant to corrosion. Refractory metals have extremely high melting points. They may also exhibit some of the same characteristics of reactive metals. The refractory metals are: Tungsten Molybdenum Tantalum .

  • Metals Metal Forms | AMERICAN ELEMENTS

    Five elements frequently defined as refractory metals include niobium, molybdenum, tantalum, tungsten, and rhenium. Common features that are shared among these metals are a melting point over 2000°C and high hardness at room temperature. Due to their high melting points, these metals are creep resistant at high temperatures. Refractory metals are prone to oxidation, however, oxide layers of ...

  • 5 Common Alloying Elements

     · Molybdenum, like chromium, has an effect on the corrosion resistance of steel. Molybdenum can also increase the hardenability, toughness, and tensile strength of steel. It increases the hardenability by lowering the required quench rate during the heat treating process to make a strong and hard steel. Molybdenum can also reduce the risk of pitting in steel as it improves resistance to .
