The price of nickel and stainless steel rose together. Nickel afternoon hand in hand with stainless steel together turn red up. Due to the temporary easing of geopolitical risks, risk assets are now picking up, nonferrous metals, stock markets, and so on have risen, the overall mood has temporarily improved. Ore prices are strong, the overlay of the epidemic on spot logistics or the formation of a certain impact. Phase, nickel and stainless steel materials to maintain high wide concussion pattern.

Nickel prices based on low inventory, tight supply and demand will still show high wide fluctuations. In addition, the current LME has low liquidity, so its sensitivity to capital will remain relatively high. Shanghai nickel-wide fluctuations are expected to continue in the 200,000-250,000 yuan wide repeated fluctuation trend. While stainless steel is affected by the stronger nickel pig iron, the cost support continues, but note that under the current demand is not effectively released, the upward space may also be affected, the stage is expected to fluctuate between 20000 and 22,000 yuan. The price of nickel produced such fluctuations, indicating that the price of the chromium oxide may also be affected to a certain extent.

Chromium oxide (Cr2O3) is a kind of dark green powder with metallic luster and belongs to hexagonal or amorphous crystal. Cr2O3 melting point is 2265℃ ~ 2435℃ and Cr2O3 density is 5.2g/cm3. It is a neutral oxide.
 
Chromium oxide has good spraying process performance, its spraying process specification is wide, it is less sensitive to overheating during spraying, and the coating is not easy to crack when local overheating occurs. The spray coating is very dense and has high bonding strength with the substrate, so it is easy to be machined such as grinding and polishing.
 
However, the deposition efficiency of pure chromium oxide powder is low, which will increase the cost of the coating. The chromium oxide coating prepared by flame spraying or plasma spraying is dense and insoluble in acid, alkali and alcohol. After proper sealing treatment, the coating can be used in the environment with chemical corrosion medium.
 
Cr2O3 coatings properties
The chemical properties of plasma sprayed chromium oxide coating are very stable, insoluble in acid, alkali, salt and various solvents, excellent corrosion resistance to medium impregnation, high temperature erosion resistance to corrosive gases such as H2S and SO2, stable to atmosphere, fresh water, sea water and light, but soluble in hot sodium bromide solution. Chromium oxide coating has good hydrophilicity and a uniform water film is formed on the surface of the coating.
 
What are Cr2O3 coatings used for?
Cr2O3 coatings can be used as abrasive wear resistant coating, hard surface wear and erosion wear coating below 540℃, cavitation wear resistant coating, corrosion wear resistant coating for parts used in chemical media below 250℃ (need to be properly sealed), such as pistons, plungers, chemical machinery shafts, pump seals, wear-resistant rings, slide valves, cylinder linings, exhaust fans, polishing and polishing fixtures, etc. Fiber wear-resistant coating, such as guide wheel, friction wheel, roller roller of chemical fiber spinning machine, magnetic conductive and wear-resistant coating, such as tape recorder head, etc.
The sprayed Cr2O coating is dark dark green with strong covering ability and high and stable thermal emissivity in a wide range of off-line wavelengths. Commonly used in infrared radiation coating (such as electric heating pipe coating), high temperature magnetic conductive wear-resistant coating, etc.

Commodities such as crude oil, wheat, cotton, and nickel have rallied since Russia's "special military operations" began in late February. On the last trading day of this quarter, commodities were on track for their biggest gain since 1990. For this reason, it is expected that the price of the chromium oxide will continue to increase.
