Following the first traffic restrictions in Beijing in 2008, China seems to be caught in traffic and air dilemmas from first-tier cities to third- and fourth-tier cities. Compared with the traditional car's tight spell, the electric car is the first to usher in the loosening. According to reports, starting from June 1, Beijing began to implement an unlimited policy for electric vehicles, including major cities such as Tianjin, Chengdu, Shanghai, and Guangzhou are also expected to follow up.
The policy of electric vehicles has directly stimulated the prosperity of the electric vehicle market. In recent years, new products and new categories of electric vehicles have emerged, especially for small and micro electric vehicles. At the 28th Electric Motor Show in South Korea, the world's first Zhidou D2 also attracted Chen Qingquan, the father of Asian electric vehicles, to personally unveil the scene.
The cold and hot situation of traditional cars and electric cars also indicates that a revolution in transportation has already begun. A new type of fifth-class travel is taking shape – people will be more accustomed to using micro-electric vehicles as a travel tool.
As a stylish smart pure electric mini car designed for urbanites, Zhidou has an ultra-convenient green economy travel mode compared to other electric vehicles. Knowing beans only need 220V household power, the mileage can reach 180 kilometers, and the average hundred kilometers of electricity costs only a few dollars. At the same time, Zhidou has super-road passability, and a regular parking space can easily stop two Beans.
Micro-pure pure electric vehicles meet the appetite of the urban population. From the perspective of urban development, the characteristics of zero-emission and low-volume occupation of micro-electric vehicles are just the punctuation of the city's pain points. The fifth-class travel mode has become An inevitable trend.

Duplex Stainless Steel Overview
Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.
Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507
Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
