Molybdenum Pipes & Tubes

We can supply seamless or welding molybdenum tube and pipe at very competitive prices of good quality. In its pure form, molybdenum is a silvery-grey metal with a hardness of 5.5. it has a melting point of 2623 °c (4753 °f); of the naturally occurring elements, only tantalum, tungsten and carbon have higher melting points. weak oxidation of molybdenum starts at 300 °c (572 °f). it has one of the lowest coefficients of thermal expansion among commercially used metals. the tensile strength of molybdenum wires increases about 3 times, from about 10 to 30 gpa. when their diameter decreases from ~50–100 nm to 10 nm.[7] molybdenum is a transition metal with an electrone gativity of 2.16 on the pauling scale and a standard atomic weight of 95.95 g/mol. it does not visibly react with oxygen or water at room temperature, and the bulk oxidation occurs at temperatures above 600 °c, resulting in molybdednium trioxide. Molybdenum is also used in steel alloys for its high corrosive resistance and weldability. molybdenum contributes further corrosion resistance to type-300 stainless steelspecifically type-316) and especially so in the so-called super austentic stainless steels (such as alloy al-6xn, 254smo or 1925hmo). molybdenum acts by increasing lattice strain, thus increasing the energy required to dissolve out iron atoms from the surface. molybdenum can also be used to enhance the corrosion resistance of ferritic (for example grade 444) and martensitic (for example 1.4122 and 1.4418) stainless steels molybdenum dusts and fumes, which can be generated by mining or metalworking, can be toxic, especially if ingested (including dust trapped in the sinuses and later swallowed).low levels of prolonged exposure can cause irritation to the eyes and skin. direct inhalation or ingestion of molybdenum and its oxides should be avoided regulations specify the maximum permissible molybdenum exposure in an 8-hour day as 5 mg/m3. chronic exposure to 60 to 600 mg/m3 can cause symptoms including fatigue, headaches and joint pains Products :-Wire ,block, rod ,round bar,bright bar, rolled bar, square , hex ,strips, flat,foil, sheet , coil,sleeting coil, plate, tubes, pipe,seamless pipes , fastner, nut bolt , crucibal, scrap, ingot ,ring, bushes, disc.SpecificationsPurity:Mo>=99.95%Density:>=9.7g/cm3Characteristic:high purityhigh strength,high melting point,outstanding thermal conductivity,excellent resistance to electrochemical corrosion,excellent resistance to oxidation at high temperatures
