Molybdenum materials in the petrochemical industry applications
The density of 10.2 g of molybdenum / cc. Melting point 2610 ℃. Boiling point 5560 ℃. In the Cape molybdenum powder made by isostatic beat green and sintered at about 2100 ℃ at 870 ~ 1260 ℃ within the range of thermal processing. Can be obtained through the plastic processing molybdenum alloy sheet, strip, foil, tubes, rods, wire and profiles, add different ingredients in the Cape after Ferrous Metals Ltd. also improve its strength and improve the low temperature ductility.
Molybdenum crucible is also very stable chemical properties, can not be hydrochloric acid, hydrofluoric acid, and the alkali etching, but in the nitric acid, aqua regia, or hot concentrated sulfuric acid may be corroded. Molybdenum is also an important additional element. Mo is effective at high temperatures accelerate the solid reinforced to prevent chloride pitting, but also improve the corrosion resistance of the stock solution.
A large demand for oil has forced people to accelerate on land and sea in deep oil extraction, and deep reservoirs often subjected to corrosive two hydrogen sulfide, carbon dioxide and high chloride brine contaminated and Molybdenum target from 0.15% to 0.25% AISI 4100 series of Cr-Mo steel is widely used. Improved molybdenum 0.4 to 0.6% of 4140 series of sulfide stress corrosion cracking (SCC) most resistant low-alloy steel, for the use of sulfur-containing wells.
With the deepening of the drilling depth and the deteriorating conditions of use, higher stainless steel containing molybdenum and nickel-based alloys, such as alloy C -22 (13% Mo) and alloy C -276 (16% Mo) applications will continue to increase. Since chromium steel surface in a thin natural protective passivation film, so stainless steel has corrosion resistance. In fact, molybdenum make this more robust passivation film, and chloride in the passivation film is destroyed it quickly regenerated. Increased molybdenum content to increase stainless steel pitting corrosion resistance and crack. 316 (2% ~ 3% Mo) is the most widely used stainless steel containing molybdenum. It is designated for food handling and processing and pharmaceuticals production and use of tanks, pipes and heat exchanger materials. Increased molybdenum content can enhance the air resistant to chlorides, so that 316 can also be used as the surrounding sea and coastal extensive use of the material of choice.
When the Mo in the air reaches a temperature above about 600 ℃ easy to form volatile oxides, the application of high temperature molybdenum preferably in an inert gas or vacuum environment

Nothing less than to proceed from the following three points
Zinc alloy products inside polishing wax cause blistering how to improve it? Nothing less than to proceed from the following three points:
First, the cleaning agent: zinc alloy products require machining before polishing, polishing wax that in addition, there is the oil needs to be cleaned. We currently on the Molybdenum target in addition to wax water except oil ineffective; wax when the blind hole or hole, hole cleaning is not clean angular position. Obviously, zinc alloy wax degreasing cleaning agent selection problem, you should choose efficient, versatile, safe, environmentally friendly zinc alloy wax except oil cleaning agents, such as zinc alloy floating-cleaning wax except oil environmental cleaning agent, in order to thoroughly to remove residual wax and oil;Second, cleaning equipment: None according to the workpiece oil, wax, shape selected to match cleaning equipment and cleaning agents can not achieve synergies;Third, the cleaning process: no basis for zinc alloy material characteristics, the characteristics of the wax, cleaning agents and cleaning equipment optimization of process parameters settings.
From the above analysis we can see that only the cleaning agents, cleaning equipment, cleaning process and choose a suitable match to fully complete the workpiece surface includes blind hole or hole, the hole sharp bit clean. Only pre-treatment been done, then, zinc alloy products will result in blistering internal polishing wax improvement.crossed cut test with 30 ° sharp hard steel knife coating surface zoned zoned 2mm apart parallel lines cut through metal coating reaches the base metal. Crossed between the base metal coating shall not escape, or cross-zoned into lmm small box, not from the skin, shedding.
3 trial rasp rasp edges from the base about a 45 ° angle, file moving coating surface, the coating should not lift or fall off.
4 Thermal shock test The large specimens in a furnace heated to 300 ℃, heat lh, and then quenched in water, the coating may not blistering, peeling separation.
If silver device can withstand the test of the above three methods, indicating that the device is electroplated silver layer adhesion is quite reliable. Of course, there are other testing methods, mainly above four.
