Shaanxi Fast Group Co., Ltd. , which has long been committed to energy-saving products for heavy-duty automotive transmissions , faces the new requirements for industrial green, low-carbon, clean and safe development, and gives full play to comprehensive competitive advantages such as equipment manufacturing, technology management and brand services, and comprehensively seizes multi-line attacks. The commanding point of energy saving has helped enterprises continue to achieve “green growth†and has emerged a new path of steady scientific and healthy development. The various production and business indicators ranked first in the Chinese gear industry for ten consecutive years. Fast Group always adheres to green and low-carbon development, which makes its products increasingly prominent in terms of fuel economy, consumption reduction, low carbon, and environmental protection. Independently developed 12-speed, 16-speed and some new all-aluminum housing transmission new products, compared with the traditional cast iron housing, reduce the weight of more than 100 kilograms, to provide the latest optimization of the vehicle to achieve lightweight and energy-saving improvements , Has become the main push product of domestic high-end heavy trucks. At present, Fast Group has become the only company in the powertrain industry in China that has won the “Efficiency Saving Award†and “The Most Fuel-efficient Transmission Award†for four consecutive years. It has also been identified as the first batch of “national-level resource-saving and environment-friendly†companies. "Friendly" companies create pilot units.

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:
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.
