The US Commerce Secretary has announced that the US will temporarily lift tariffs imposed on Ukraine during the Trump administration to help Ukraine recover its economy and continue to show support for the Russia-Ukraine situation. "For steel mills to remain an economic lifeline for the Ukrainian people, they must be able to export steel," the Commerce Department said in a statement.
The Biden administration will announce the lifting of steel tariffs on Ukraine for one year. Ukraine is a fairly small supplier of U.S. steel, shipping about 218,000 tons in 2019, ranking it 12th among foreign suppliers to the United States, the report said. The U.S. Commerce Department noted that the steel industry is uniquely important to Ukraine's economic strength, with one in 13 people employed in the steel industry.

Overview of vanadium nitride VN powder
Vanadium nitride is formed during the nitriding process of steel and increases wear resistance. During the nitridation process, another phase V2N (also known as vanadium nitride) can be formed together with VN. VN has a cubic rock salt structure. There is also a low-temperature form, which contains the V4 cluster. The low temperature phase is caused by dynamic instability when the vibrational mode energy in the high temperature NaCl structural phase drops below zero.
Vanadium nitride is a strongly coupled superconductor. Nanocrystalline vanadium nitride is said to have potential for use in supercapacitors. The properties of vanadium nitride are sensitively dependent on the stoichiometry of the material.
How is vanadium nitride VN powder produced?
The samples made of ammonium metavanadate powder and carbon powder were pre-reduced in a heating furnace, followed by final reduction. After the final reduction is completed, the sample is cooled with the furnace, and the obtained sample is vanadium nitride; in the process, the temperature in the heating furnace is 650-670° C., and the holding time of the heating furnace is 2-4 hours. Under the conditions of this temperature and holding time, the surface of the sample can be prevented from melting and hindering the reduction reaction.
After pre-reduction, the main reduction product of the sample is V2O3, and the rest are carbides and a small amount of VN; in the final reduction process, the sample is kept at 1300-1500 °C. CO gas and CO gas are generated during the insulation process. The introduced nitrogen gas is taken away, and VN is obtained after the insulation is completed; the nitrogen flow rate during the reaction is 210-270 mL/min, which can not only meet the kinetic conditions of the reduction reaction, but also prevent the reaction temperature caused by too much nitrogen. reduce and waste nitrogen;
Application of vanadium nitride VN powder
Vanadium nitride has high wear resistance, which can greatly improve vanadium steel after nitriding.
The comprehensive mechanical properties of high-strength steel, such as strength, toughness, ductility, and thermal fatigue resistance, endow the steel with good weldability. In the case of achieving the same strength, adding vanadium nitride can save 20-40% of the vanadium addition, thereby reducing the cost.
Vanadium-nitrogen alloys can be used in structural steel, tool steel, tubular steel, rebar and cast iron. Vanadium Nitride Alloys for High Strength Low Alloy Steels
Vanadium nitride can carry out effective vanadium-nitrogen microalloying at the same time, promote the precipitation of carbon, vanadium and nitrogen compounds in steel, and play a more effective role in strengthening sedimentation and refinement.
Adding vanadium nitride to steel can improve the comprehensive mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance, so that the steel has good weldability.
In the case of achieving the same strength, adding vanadium nitride can save 30-40% of the vanadium addition, thereby reducing the cost. Vanadium-nitrogen alloys can be used in structural steel, tool steel, tubular steel, rebar and cast iron.
The vanadium-nitrogen alloy used for high-strength low-alloy steel can simultaneously carry out effective vanadium-nitrogen microalloying, promote the precipitation of carbon, vanadium and nitrogen compounds in the steel, and play a more effective role in sedimentation strengthening and graining. refinement.

During the first 100 days of its special military operation in Ukraine, Russia earned 93 billion euros from fossil energy exports, most of it from the European Union, according to an independent research center.
The report by the Finland-based Center for Energy and Clean Air comes as Ukraine urges the West to cut off all trade with Russia to stop funding the Kremlin's war chest.
The European Union recently decided to impose a gradual embargo on Russian oil imports, with some exceptions, according to reports. Russian gas, on which it relies heavily, is currently unaffected.
In the first 100 days of the Conflict between Russia and Ukraine (February 24 to June 3), the EU accounted for 61 percent of fossil energy imports, or about 57 billion euros, according to the Energy and Clean Air Research Center.
Russia's revenue came first from crude oil sales (43.87 billion euros), followed by pipeline gas (22.89 billion euros), then petroleum Vanadium Nitride VN, Vanadium Nitride VN Overview, Vanadium Nitride VN Application, Vanadium Nitride VN Supplier, Vanadium Nitride VN Price, please feel free to contact us and send an inquiry.
