Low fuel consumption and good service become its outstanding features
Faced with the threat of high oil prices and high maintenance costs, auto users want to be able to minimize the cost of vehicles, which is particularly prominent in the “cost-resolved†heavy-duty industry. The National 3rd emission standards that have been implemented since July 1 have prompted many heavy truck companies to seek breakthroughs in energy-saving and emission reduction technologies.
On September 1, Shaanxi Automobile produced a new generation of super fuel-efficient heavy trucks - Shaanxi Auto's second-generation national triple card, which achieved a new breakthrough in the field of energy conservation through the "full upgrade" of vehicle technology. People's wide attention. It is reported that Shaanxi Automobile's second-generation national triple-card fuel-saving advantage, in addition to its unique ability to meet various needs such as no-load, light-load, full-load, etc., improves vehicle economy, and increases revenue, it also integrates It has been upgraded to the 7th generation engine computer control program to make the low fuel consumption area of ​​the vehicle work more widely. The fuel consumption per 100 kilometers can be reduced by about 4 liters.
For Shanxi Energy's second-generation national triple-card energy-saving effect, Ding Xingfu, a user of Shanxi Datong, has a deeper experience. He said: “My biggest feeling is that I can save fuel, which is probably 10% more than that of the same type of country.†This car is fully loaded and empty. In other cases, the start-up performance is very good and the power is very strong, which is very suitable for the harsh environment of our coal operations."
At the same time as upgrading technology, in order to improve the service quality of China's triple card, Shaanxi Automobile has successfully completed the nationwide launch of the second-generation country-three accessories on August 26th. Some standing and special parts were put into place first, and they seized the country. Triple card service commanding heights.
People in the industry believe that the launch of Shaanxi Auto's second-generation national triple card not only saves users cost and creates value, but also consolidates the leading position of Shaanxi Auto Heavy Duty Truck Industry. Its integrated use of various cutting-edge technologies is even more significant in China. The development of triple-card fuel economy and environmental protection technologies has provided a new idea and promoted the development of the national triple-card technology.

Duplex Stainless Steel
Duplex Stainless Steels Available
Haohua Industrysupplies LDX2101, 2205, Ferralium 255, Zeron 100 and LDX2507 in the form of plate, sheet, strip, bar, pipe, tubing, pipe fittings, flanges and weld wire.
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.
