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.
Affected by the ever-changing international situation, the supply and prices of international bulk tungsten disulfide are still very uncertain.
What is WS2 coating?
Tungsten disulfide is an extremely smooth dry film lubrication coating. Tungsten disulfide friction coefficient is very low (only 0.03), which is lower than that of Teflon, graphite or molybdenum disulfide (MoS2). Compared with many other lubricant materials, the film is very durable and can withstand extremely high loads of more than 300000 psi. WS2 has unparalleled performance in lubrication, non-stick, low resistance, wear life and load rating.
What are advantages of tungsten disulfide?
WS2 is an excellent demoulding material for plastic moulds, extrusion moulds and other demoulding applications.
WS2 eliminates the need for liquid lubricants and can also be used with petrified oils, greases, synthetic oils, silicone lubricants and hydraulic oils. It has an affinity for lubricants and maintains the fluid power layer. It helps to keep the oil or grease on the surface, thus further increasing lubrication.
In the case of less than 1 micron thick, the coating can be applied to high-precision parts without tolerance problems.
WS2 is also a rather inert and non-toxic material, which has been used in medical devices and food processing applications.
WS2 is applied to customer substrates through high-speed ambient temperature process. It does not cause the substrate material to anneal or warp.
WS2 can be used alone or in combination with our PVD hard coating to improve durability.
WS2 coating properties
Lubricity-the lowest friction coefficient of solid materials!
The dynamic friction coefficient is 0.03 and the static friction coefficient is 0.07.
Excellent release performance. They don't stick together.
Prevent scratches, jams or cold welds.
It can be used at a load of more than 300000 pounds per square inch!
High temperature resistance.
Extremely thin 1 stroke 2 micron coating thickness.
Unlike many powder lubricants, it can be bonded to the substrate without using a binder.
Do not crumb, peel off or peel off.
Ultra-thin-suitable for high precision components.
WS2 eliminates the need for liquid lubricants.
Can be used with oil and grease. It has an affinity for lubricants and maintains a fluid dynamic layer.
How is WS2 coating applied?

The EU’s draft REPowerEU plan calls for an increase of 15TWh of rooftop PV capacity by 2022. The draft also calls for EU and national governments to take action this year to reduce the time required to obtain permits for rooftop PV installations to three months, and proposes that "all new buildings and existing buildings with an energy grade OF D or above should have rooftop PV installations by 2025".
In addition, the European Commission is likely to set a target for installed PV capacity of 300GW by 2025 and 500GW by 2030. Some members are more aggressive, with Austria, Belgium, Lithuania, Luxembourg, and Spain demanding a 1TW target for 2030.
The REPowerEU initiative, worth 195 billion euros, was proposed by the EU on March 8 to phase out member states' dependence on Russian fossil fuels by 2030. In a few days, the European Commission will present a package to implement the RePowerEU strategy.
As an important application scenario of distributed PV, rooftop PV is not limited to land, and the development conditions are relatively convenient.
Since the end of 2021, Spain, France, the Netherlands, and other countries have introduced policies and measures such as government subsidies, tax cuts, fee reductions, and accelerated grid-connection approval to encourage the development of distributed PV. Europe's potential for rooftop PV is huge and will continue to be an important growth pole for the industry, according to Wood Mackenzie.
