A Carbon Steel Plate has usually been considered as the steel that does not contain much alloy steel elements, also named as mild steel. Generally, elements are C, Mn, P, S, Si, besides these, there are no minimum limits for elements of Al, Cr, Ni, Mo, V, etc.
Carbon steel plates are available in different grades depending on the carbon content and strength.
As the content of Carbon increase, the steel plate hardness increases.
Low carbon steel plate: For carbon content 0.06% to 0.25%, also we call it Mild Steel Plate.
Medium carbon steel plate: C content from 0.25% to 0.55%.
High carbon steel plate: 0.55% to 1.0%, also called hard steel plate.
Low carbon steel is the most common form, and it's very malleable and ductile. Medium carbon steel balances ductility as well as strength for excellent wear resistance. High carbon steel is exceptionally strong, while ultra-high carbon steel can be tempered to even greater hardness but no malleability.
As the percentage of carbon gets larger, steel can become harder and stronger through heat-treating. Carbon steel is usually heated to change the mechanical properties of steel, usually ductility, hardness, strength, and resistance of impact. Increasing the carbon content of carbon steel makes it harder and stronger, but reduces the steel`s ability to be welded, making it more brittle.
Carbon steel plate is most often used for structural purposes such as buildings, yet it has the flexibility to be worked into ornate designs. Low carbon steel sheet (wrought iron) is typically used for fences, chain links, gates, and railings. Structural steel (medium carbon steel) is used in cars, refrigerators, washing machines, buildings, and bridges. The steel sheets are normally made up of medium carbon steel.

On April 28th, 2011, the 14th Shanghai International Automobile Industry Exhibition with the theme of “Innovation•Future†was successfully concluded at Shanghai New International Expo Center. At the world-famous Shanghai Auto Show, Fast's new 9-gear debut products have attracted great interest from the industry and are well received by users. They have fully demonstrated Fast's brand image and independent innovation results. 
National brands and independent brands are making a great appearance at this auto show. Fast is the only Chinese transmission enterprise that has settled in the International Exhibition Hall. More than 80% of new heavy-duty vehicle products exhibited by domestic exhibitors are equipped with Fast Transmission, which fully demonstrates Fast's brand appeal and product technology content. The Fast exhibition area covers an area of ​​150 square meters. The blue-and-white multi-buildings are magnificent and eye-catching. The 9 new transmission products exhibited are the most popular spots in the exhibition hall.
FAW Jiefang, FAW Qingdao, Dongfeng Commercial Vehicle, Dongfeng Liuzhou Auto, Shaanxi Auto, Hualing, Beiben, Yutong, Jinlong and senior executives from domestic and foreign companies such as WABCO, Caterpillar, Eaton and Volvo have come to visit the booth. Fast's strong product research and development capabilities, advanced production and manufacturing levels, and highly efficient and convenient service network are highly valued. It also stated that it will continue to focus on supporting Fast's development, and constantly consolidate and expand the cooperative relationship between the two parties to jointly develop the automotive industry. The innovative development made new and greater contributions.
Fast company leaders visited the site to guide their work and met with visitors respectively to introduce the technical performance and technological advantages of Fast's new products. Fast exhibited at the current auto show 20 stalls (double 10 gear), 6DS180 (with retarder), 6DS60/50/40T, 5J55T, AMT (16 gear), 10 gear full helical gear synchronizer, 12 The all-aluminum alloy housing, CX28, CX31 and other 9 series transmission new products have obvious advantages such as high technology content, high performance-price ratio, energy saving and environmental protection, and can be widely used in trucks, off-road vehicles, tractors, construction machinery, passenger cars, etc. Special vehicles, medium and low-speed trucks and other fields represent Fast's latest technological innovations and international advanced levels of AMT and AT heavy-duty vehicle transmissions, providing the latest optimized configurations for the upgrading of domestic heavy-duty vehicles.
Among them, the 20-speed (double 10-speed) series transmission is a heavy-duty mechanical transmission new product launched by Fast at the Shanghai Auto Show 2011. It has three configurations: direct, overdrive, and double overdrive, with a speed ratio range. It is widely used in trucks, tractors and various special vehicles because of its wider features, narrower speed ratio, better fuel economy, better ability to climb and overspeed, and adaptability to wider roads. The 20-speed transmission series has passed the road test and won wide acclaim from the direct users. It can save more than 2 liters of fuel per 100 kilometers, and the economic benefits are very obvious.
During the exhibition, Fast and WABCO jointly held a press conference for the new products of Fast and Authentic AMT and Fast; together with Caterpillar, a Fast Caterpillar joint venture company was established. The new product press conference was a grand launch of AMT and AT automatic transmissions that represent the international transmission industry's top level to all OEMs and all sectors of society.
