ASTM A588 steel includes Class A, Class B, Class C, and Class K. The ASTM A588 steel specification is based on the standard specification for high-strength low-alloy structural steel with a lower yield point of up to 50ksi for applications requiring high strength and corrosion resistance.
A36/Q235/S235JR Carbon Steel Coil
A36 is a low-carbon steel containing trace amounts of manganese, phosphorus, sulfur, silicon and other elements such as copper. A36 has good weldability and high yield strength, and is the structural steel plate specified by the engineer. ASTM A36 steel plate is often manufactured into a variety of structural steel parts. This grade is used for welded, bolted or riveted construction of bridges and buildings, as well as for general structural purposes. Due to its yield point, A36 carbon plate can be used to design lighter-weight structures and equipment, and provide good weldability. Construction, energy, heavy equipment, transportation, infrastructure and mining are the industries where A36 panels are commonly used.
A179 seamless cold drawn low carbon steel pipe is equivalent to China's No. 10 high-quality low-carbon steel. A179 is suitable for cold-drawn high-quality low-carbon seamless steel pipes for heat exchangers and condensers.
304 stainless steel is a kind of universal stainless steel material, rust resistance than 200 series of stainless steel material is stronger. High temperature resistance is also better, can be as high as 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is concluded in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of less than or equal to 65% of the boiling temperature. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.
A36 is a low-carbon steel containing trace amounts of manganese, phosphorus, sulfur, silicon and other elements such as copper. A36 has good weldability and high yield strength, and is the most specified structural steel plate by engineers. ASTM A36 is most commonly manufactured as a variety of structural steel parts. This grade is used for welded, bolted or riveted construction of bridges and buildings, as well as for general structural purposes. Due to its lowest yield point, A36 can be used to design lighter-weight structures and equipment, and provide good weldability.
202 stainless steel is an austenitic chromium-nickel-manganese alloy. It has high ductility, good corrosion resistance and excellent toughness in both high and low temperature environments. 202 stainless steel is one of the most widely used 200 series stainless steel. 202 stainless steel, the austenitic structure is stabilized by the addition of nickel and manganese, thereby preventing the formation of harmful phases, such as sigma phase or chromium carbide. The high nickel content also improves the corrosion and oxidation resistance of the steel at high temperatures.
The differences between the, B and C designations are complex and related to structural tolerances. For steel mesh products, B500A grade steel is usually used, and for steel bars, B500B grade steel is used. B500C steel is rarely required, and it is always worthwhile for structural engineers to check whether B500B grade steel can be used instead of B500C, because B500C usually has a significant cost overhead.
H-beam is a new type of steel for economic construction. H-beam has economical and reasonable cross-sectional shape, good mechanical properties, uniform extension of each point on the cross-section and small internal stress during rolling. Compared with ordinary I-beam, H-beam has the advantages of large cross-sectional modulus, light weight and metal saving, which can reduce the building structure by 30-40%. In addition, because its legs are parallel to the inner and outer sides and the leg ends are right angles, the welding and riveting work can be saved by 25%. It is often used in large buildings (such as factories, high-rise buildings, etc.) with large bearing capacity and good cross-sectional stability, as well as bridges, ships, lifting and transportation machinery, equipment foundations, supports, foundation piles, etc.

The difference between steel coil and steel strip
Although both steel coils and steel strips are steel products, they have different forms and applications. Steel coils are mostly in the form of rolls, which are more suitable for industrial applications that require large amounts of continuous materials; while steel strips are narrow and long, which are more suitable for specific applications that require precise dimensions and high surface quality.
Steel pipe material
Steel pipes can also be divided into seamless steel pipes and welded steel pipes according to the production process. Seamless steel pipes are divided into hot-rolled and cold-rolled (drawn). Welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes.

How are steel bars produced?
The production of steel bars is a complex process that requires the cooperation of a series of equipment. The accuracy and stability of these equipment directly affect the quality of the bars.

The difference between I-beam and H-beam
The upper and lower flanges of H-beams are usually wider than those of I-beams. H-beams also perform better in terms of load-bearing capacity and stability, and their bending resistance is particularly good. Therefore, H-beams are more suitable for structures that need to withstand large loads, such as bridges and high-rise buildings.

What is the function of angle steel
Angle steel is used to construct floor structure brackets and supporting materials. It has strong load-bearing capacity and good durability, and can meet the requirements of building structure for strength and stability. In addition, it can also be used to fix doors and windows, strengthen the connection of the frame and support the installation of plugs.
