Sytop Silver Tungsten Alloy with Wear Resistance and Corrosion


    Corrosion resistance of the outermost layer of Silver Tungsten Alloy should use higher extrusion ratio and higher extrusion temperature to improve the ability to obtain direct assistance by extrusion of products and intermediate products. In order to prolong the mold life and to ensure the product dimensions and surface quality, glass lubricant lubrication should be used for zirconium dioxide or aluminum oxide refractory mold coating, extrusion. Including caulking and ordinary forging. Crimp the blank used for 2.5 mm production and drawing small diameter pulling bar material, the billet is square sintered body of about 10 ~ 30 mm.

    Pure molybdenum caulks the open forging temperature, usually about 1400 ° C, the amount of deformation pass is generally 10 to 20%, up to about 30%. As the diameter decreases, the forging temperature decreases gradually and the diameter 3 mm can decrease to about 800 ° C. Hammer forging forging that is more suitable than forging and forging. For ordinary forging, large billets and large forged products can be obtained. A pure molybdenum forging temperature of about 1400 ° C can be lowered while opening by pushing the billet forging temperature. Free forging should pay attention to safeguard against workpieces or debris scattering from the wound for the manufacture of sheets, strips, foils and bars.

    According to the world's molybdenum consumption statistics, the application of molybdenum in the steel industry is still the most important position. Improve corrosion resistance of steel in acid solution and liquid metal; to improve molybdenum and hardenability like steel strength, especially high temperature strength and toughness, by alloying elements in steel, to improve the wear resistance of steel Improved, weldable heat resistance. Molybdenum is a good carbide forming element and steelmaking does not oxidize when it can be used alone or with other alloying elements. Consumption of molybdenum special steels during periodic growth is currently 0.201 kg, the consumption of molybdenum special steel per ton per ton. Molybdenum and chromium, nickel, manganese and silicon can produce kinds of stainless steel, tool steel, high speed steel and alloy steel. Stainless steel, corrosion resistant steel with excellent corrosion resistance can be used to add about 6% molybdenum, oil exploration, stainless steel, titanium desalination device, ocean shipping, marine oil and gas production It can be used instead of tubing. Such stainless steel can also be used for car enclosure, sewage treatment equipment.

    However, there are many problems with this surface technology. Many parts of the steel industry are medium carbon high strength steel or alloy steel, these are hardened and easily cracked by hand arc welding. Repair welding overlay manual arc prevents material and substrate cracking when matrix material requires preheating to weld with operating manual arc argon arc and relatively high preheating temperature of 300-500 ° C is required There are a lot of difficulties to do, the working environment has deteriorated.

    Cobaltalloys that from have higher melting points than nickel (or iron) alloys ,This gives them the ability to absorb stress to a higher absolute temperature.

    Cobalt alloys give superior hot corrosion resistance to gas turbine atmospheres , this is due to their high chromium content.

    Cobalt alloys show superior thermal fatigue resistance and weldability over nickel alloys.

    ---Excellent wear and corrosion resistance even at high temperature up to 800℃

    Shenyang Top New Material Co.,Ltd cobalt base alloys is a range of Cobalt Chromium Alloy with wear resistance, corrosion and high thermal resistance. It is widely used in oil & gas, machinery, wood cutting, automotive, paper and food processing industry etc.
