Types of Carbon steels

As a group carbon steels are the most frequently produced and used steels. More than 85 % of the steels produced presently are carbon steels. Normally carbon steels contain up to 2 % total alloying elements and can be sub divided into ultra low carbon, low carbon, medium carbon, high carbon and ultra high carbon steels. These steels are described below.
Ultra low carbon steels – These steels contain very low carbon usually less than 0.10 %. These steels also contain very low manganese and very low silicon. These steels are having extra deep drawing properties and usually produced in the form of flat and wire rod products.
Low carbon steels – These steels contain up to 0.30 % C. This category includes mild steel with carbon content usually in the range of 0.15-0.30%. The largest category of this class of steel is flat rolled products in the form of sheet or strip usually in the cold rolled and annealed condition. The carbon content for these deep drawing quality steels is around 0.10 % C, with up to 0.5 % manganese. For structural use produced in the form of plates and sections, the carbon content may be increased up to 0.30 %, with higher manganese content up to 1.6 %.
Medium-carbon steels – These steels are similar to low carbon steels except that the carbon content in these steels are higher and normally in the range of 0.31% to 0.60 % and the manganese from 0.60 % to 1.65 %. Due to Increased carbon content, the medium carbon steels can be used in the quenched and tempered condition. The medium carbon steels are used as shafts, axles, gears, crankshafts, couplings and forgings. Steels in the 0.40 % to 0.60 % C range are also used for rails, railway wheels and rail axles.
High carbon steels – These steels have carbon content ranging from 0.61 % to 1.00% with manganese content ranging from 0.30 % to 0.90 %. The use of high carbon steels includes in springs, pre stressed concrete wires and high strength wires etc.
Ultrahigh carbon steels – These steels contains carbon in the range of 1.25 % to 2.0 %.  These steels are normally thermo-mechanically processed to produce microstructures consisting of ultra-fine, equi-axed grains of spherical, discontinuous pro-eutectoid carbide particles.

Structural steels in Steel plant

Structural steel is a standard construction material made from specific steel grades and is available in industry standard cross sectional shapes. This steel exhibits desirable physical properties such as strength, uniformity of properties, light weight and ease of use etc.
Major applications for these steels are in high rise and tall multi-storey buildings, industrial buildings, towers, tunnels, bridges, road barriers and industrial structures etc.

The common shapes in which structural steels are available consist of sections (beams, channels, Tees section and angles), squares and rounds, hexagons, plates, pipes, hollow square sections, steel cable, Z sections and cold formed sections etc. 

Structural steels for use at ambient or moderately elevated temperatures are of the following types.
1. Carbon and carbon-manganese steels – In these steels the maximum content for alloying elements does not exceed the following: (i) manganese – 1.65 %, silicon – 0.40 % and (iii) copper – 0.6 %. The specified minimum of copper does not exceed 0.4 % and also there is no minimum content is specified for other elements to obtain a desired alloying effect.
2. High strength low alloy (HSLA) steel
3. Heat treated high tensile steels 
4. Constructional alloy steels
5.High performance steels – These steels are with enhanced notch toughness and generally used in construction of bridges.

Benefits of Using steel frames

The steel industry is undoubtedly an important contributor to the economy. Most of the construction companies available in the market uses steel frame to build heavy infrastructure, and some of the main reasons owing to which steel frames is used over other types of infrastructure available in the market is its benefits which it gives to its customers.

Advantages of steel framing
Generally,building construction is finished with the help of mild steel instead of using the most powerful tool present in the market. This mild steel is very durable and strong to use, and can be used under every circumstance or for building strong infrastructure and buildings. The features of steel framing is as following:
1. Flexible, The mild steel frames can be easily bended or molded according to the comfort of the user.2. Ductility, The soft and appropriate material of the frame will not crack in extreme conditions and instead stays intact to be used for different purposes on the construction site.
3. Durable, These are very durable to use, because they can last for a longer period of time and users need not have to bear cost for replacement again and again.

Where to use steel frames?
Before the steel frames or different kinds of cladding rails are put to use, it is important to understand what their different types are and uses which can deliver the best output to the users. Following are the kind of frames which can be used;

Fujian Putian Geili Machinery manufacturing Co., Ltd was founded in 2006, the registered capital of 20,000,000 yuan. The company is located in one of the city center onn the west side of the Straits Economic Zone, Xianyou Putian. We are not only a manufacturer of steel machinery, but we have our own steel mill, which can produce deformed bar, angle bar, round steel, wire rod, steel coil, steel plate etc. If you have inquiry in these area, pls don't hesitate to contact us.
