[Published report] The number of Henan netizens ranked first in the middle
The "Report" systematically reveals the situation of Henan netizens, as well as Internet resources, security and Internet applications in our province.
According to the "Report", as of the end of June this year, the number of Internet users in our province was 50.99 million, ranking 6th in the country and the first in the six provinces. The number of netizens reached 57.55 million, of which 47.35 million were mobile phone netizens, and the penetration rate was about 80%, higher than the national average.
According to Zhao Huiqun, deputy director of the Provincial Communications Administration, among the 18 provincial cities in the province, Zhengzhou people are the most â€œloveâ€ Internet users, and the number of Internet users is the first, followed by Nanyang and Zhoukou. The size of netizens is 6.55 million. 5.79 million, 5.01 million. According to the "Report", Jiyuan, Hebi and Sanmenxia are the three cities with the least number of "touch nets" in our province.
On the other hand, Henan, as a major agricultural province, shows a clear contrast between urban and rural Internet users. As of the end of June this year, the number of urban netizens reached 35.8 million, accounting for 62.2%, lower than the national average of 9.9 percentage points; the number of netizens in rural areas was 21.75 million, accounting for 37.8%, higher than the national average of 9.9 percentage points. .
The "Report" also accurately images the netizens in our province: from the perspective of gender, there are 6 "handsome guys" and 4 "sisters" in every 10 Henan netizens. From the income situation, middle-income and non-income people prefer to go online, high. Income earners and low-income people have less access to the Internet; with academic qualifications as the coordinates, they are â€œsymmetricâ€ curves â€“ high school, technical secondary school, technical school education level, the most loved online, less than primary school and undergraduate or above; from professional perspective, in my opinion Provincial employees, self-employed, and students have the largest number of Internet users. From the perspective of Internet applications, Henan netizens have a higher tendency to use online trading applications. Online shopping, online banking, online payment, and online stock trading are all higher than the national average. Level.
The "Report" also disclosed that as of June this year, the number of websites registered in our province was 152,000, ranking eighth in the country. The website was "hanging horse" and the website was detained in the top ten in the country. The number reached 703,000, ranking fifth in the country.

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 ZeronÂ® 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.
