Judging from the current state of development of China's environmental protection machinery and equipment, technologies such as basic atmospheric treatment, urban sewage and industrial wastewater treatment, solid waste treatment, etc. have reached a certain level, but compared with the current development status of foreign industries in the same industry, The level of large-scale environmental protection equipment in China is still hard to see.
Industry experts agreed that under the support of state policies, there is ample room for development of China's environmental protection machinery industry. The environmental protection machinery industry should seize this historical opportunity, do a good job of digestion and absorption, and re-innovation on the basis of absorption, and accelerate the development of large-scale key equipment. The pace. The development of the environmental protection machinery industry will also drive the development of related industries. There will be many industries that benefit from such industries as mining machinery, general machinery, instrumentation, chemical machinery, information industry, and biochemistry. As a sunrise industry, the development space for the environmental protection machinery industry is undoubtedly enormous. At present, the biggest bottleneck in the localization of major environmental protection technology and equipment is the lack of institutional backwardness and innovation.

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.
