The so-called cryogenic treatment is to use liquid nitrogen (-196 C) as a cooling medium to continue the cooling process of the quenched metal material to a temperature far below room temperature, which promotes the acquisition of residual austenite after conventional heat treatment. Further transformation to improve the performance of metal materials. After the cryogenic treatment of metal, the wear resistance, toughness and dimensional stability of metal workpieces can be significantly improved, and the service life of the workpiece is doubled. Measuring Cryogenic Treatment--Technical Application Cryogenic processing equipment is a new technology that places the workpiece to be processed in a specific and controlled low-temperature environment, changes the microstructure of the material, and improves or improves the performance of the material. The temperature of cryogenic treatment is generally -100 C ~ -196 C. Due to the change of the microstructure of the treated material in a low temperature environment, the macroscopic performance is the surface hardness, impact toughness, wear resistance, dimensional stability, Improvements and improvements in strength, residual stress, etc. At present, our research on cryogenically treated materials involves: High-speed steel W9, W6, mold steel 3Cr13, carburized steel 20CrMnTi, high-chromium cast iron, high vanadium cast iron to improve the wear resistance of the workpiece and extend the service life; hard alloys such as aluminum alloys 2A11 and 2A12 to improve the dimensional stability of materials; Low temperature impact toughness of 42CrMo, 35CrMo.

Chemical name: Sodium Sulphide Na2S. Product NO.: 28301010 CAS NO. : 1313-82-2 Molecular Ormula: Na2S Molecular Weight: 78.04 Standard: GB/T10500-2009 Applications Used as reducing agent or mordant agent in making sulphur dyes, as flotation agent in non-ferrous metallurgical industry, as mordant agent for cotton dying, used In tanner industry, in pharmacy industry making some phenacetin, in electroplate industry, for hydriding galvanize. Nature: yellow or red flakes, strong moisture absorption, soluble in water, and water solution is strongly alkaline reaction. Sodium sulphide will cause burns when is touched with the skin and hair. The method of solution in the air will slowly oxygen. Sodium thiosulfate, sodium sulfite, sodium sulphide and sodium polysulfide, because sodium thiosulfateâ??s generating speed is faster, its major product is sodium thiosulfate. Sodium sulphide is deliquesced in the air and carbonated so that it is metamorphic, and constantly release hydrogen sulfide gas. The industrial sodium sulphide includes impurities, so its color is red. Specific gravity and boiling point are influenced by impurities.  Function and Usage: sodium sulphide is used to produce vulcanization dye, sulphur cyan, sulphur blue, dye intermediates reductance, and other nonferrous metallurgy industry used for ore flotation agents. Sodium sulphide can also make the depilatory cream in the leather industry. It is cooking agent in the paper industry. Meanwhile, sodium sulphide is also used to produce Sodium thiosulfate, sodium sulfite and sodium polysulfide.
