State III standard rejects countermeasures


After delaying again and again, it began yesterday and the country has imposed the National III standard. Two years after the implementation of the National III standard in Beijing, Shanghai, etc., the National III standard finally covered the whole country, but implementation in various places is still a lot of tricks. The large number of inventory of the national standard II model still passed various “countermeasures” to increase sales. .

Since it was decided that the National III emission standards would be implemented nationwide two years ago, most passenger car manufacturers already have the ability to produce the country's III models, so there are no barriers to the production technology of the models. However, some self-owned brands and commercial vehicles are still the "hardest-hit areas" of the National III standard. There are also many inventory country II cars that have not been sold. The outlook for this type of vehicle after the full implementation of the National III standard is still not optimistic.

The low-end autonomous passenger vehicles, pickup trucks and heavy truck market are the "difficult households" of the National III standard. Many high-level manufacturers are negotiating with local governments through various means to delay the implementation of State III limits. "We are negotiating with the local government to strive for a three-month extension of the implementation of the State III." Yesterday, a sales manager of a large commercial vehicle company told the "First Financial Daily" that "to strive to complete the inventory of the first half of the digested. ”

There are a lot of independent brands that have accumulated a lot of unqualified new cars. In areas such as Ningxia, Guizhou, Hebei, Liaoning, and Sichuan, many dealers are still selling the country’s II models, and some dealers have said that it will take at least a few months if they are to digest the stock cars. The adoption of environmental inspections in advance is a common method adopted by these dealers. After passing the inspection, the vehicles can still be sold after July 1.

In addition, some manufacturers have moved in and out of the country and have been looking for policy vacancies in the economically backward areas to digest the country's II inventory. A car company in the central region will concentrate the current backlog of nearly 2,000 vehicles of State II to the western region. “We will first obtain a buffer period of about six months through the policy approval of some of these provinces to digest the inventory.” Understand that, in consideration of local taxation and ensuring economic development, certain regions will open green lights for these substandard vehicles.

Iron Based Alloy Powder

Iron-based alloy powder is commonly used in plasma transfer arc welding (PTAW) due to its excellent mechanical properties and high resistance to corrosion and heat. This type of powder is typically composed of iron as the base metal, along with various alloying elements such as nickel, chromium, molybdenum, and tungsten.

The specific composition of the iron-based alloy powder may vary depending on the desired properties and application requirements. For example, adding nickel can increase the strength and toughness of the weld, while chromium enhances the corrosion resistance. Molybdenum and tungsten are often added to improve the high-temperature strength and creep resistance of the weld.

Iron-based alloy powders for PTAW are available in various particle sizes, typically ranging from a few micrometers to several hundred micrometers. The powder is usually fed into the plasma arc through a powder feeder, which ensures a controlled and consistent supply of powder during the welding process.

During PTAW, the powder is melted and deposited onto the workpiece, forming a weld bead. The high energy plasma arc provides the heat necessary to melt the powder and the base metal, creating a strong and durable weld joint.

Overall, iron-based alloy powder for plasma transfer arc welding offers excellent weldability, high mechanical properties, and resistance to corrosion and heat, making it suitable for a wide range of applications in industries such as aerospace, automotive, and power generation.
