Structural steel refers to steel that meets specific strength and formability grades. Formability is expressed as elongation after break in tensile test. Structural steel is generally used for load bearing and other applications where the strength of the steel is an important design criterion.
Structural steel can be subdivided into: carbon structural steel, High-Quality Carbon Structural Steel, low-alloy high-strength structural steel, alloy structural steel, Spring Steel, weathering structural steel, chip-free structural steel, non-quenched and tempered mechanical structural steel, etc.
Compared with ordinary carbon structural steel, high-quality carbon structural steel has lower content of sulfur, phosphorus and other non-metallic inclusions. According to the different carbon content and use, this kind of steel is roughly divided into three categories:
1. Less than 0.25% C is low-carbon steel, especially 08F, 08Al, etc. with carbon content less than 0.10%, which are widely used as deep-drawing parts such as automobile, manufacturing, etc. due to their good deep-drawing and weldability Tanks...etc, 20G is the main material for making ordinary boilers. In addition, low carbon steel is also widely used as carburizing steel for machinery manufacturing.
2. 0.25~0.60%C is medium carbon steel, which is mostly used in the quenched and tempered state to make parts for the machinery manufacturing industry. Quenching and tempering is 22~34HRC, which can obtain comprehensive mechanical properties and facilitate cutting.
3. More than 0.6% C is high carbon steel, which is mostly used to manufacture springs, gears, rolls, etc. According to the different manganese content, it can be divided into ordinary manganese content (0.25-0.8%) and higher manganese content (0.7 ~ 1.0% and 0.9 ~ 1.2%) two steel groups. Manganese can improve the hardenability of steel, strengthen ferrite, and improve the yield strength, tensile strength and wear resistance of steel. Usually, "Mn" is added after the grade of steel with high manganese content, such as 15Mn, 20Mn, to distinguish it from carbon steel with normal manganese content.

The steel plate is a flat steel that is cast with molten steel and pressed after cooling.
The Steel Sheet is flat, rectangular and can be directly rolled or cut from wide steel strips.
The steel plates is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm.
Steel sheets are divided into hot rolling plate and cold rolling plate according to rolling.
1. Hot Rolled Steel Plate
Hot rolling processing methods include hot rolling, forging, extrusion and other methods.
2. Cold Rolled Steel Plate
Cold rolling processing methods include cold rolling, cold drawing and cold drawing, cold bending, cold extrusion and other methods.
The cold rolling method is to continue processing the hot rolled steel below the recrystallization temperature to make it cold rolled steel. Using cold rolling processing method can improve the mechanical properties of steel, and obtain products with high dimensional accuracy and certain smoothness.
