Tuspipe’s A36 Steel Specifications: Chemical, Mechanical, and Physical Properties

Tuspipe’s A36 Steel Specifications: Chemical, Mechanical, and Physical Properties

A36 steel is one of the most widespread mild steels in the world. It is favored as it is powerful, flexible, and less expensive. The steel is extensively used in construction, bridges, and other infrastructures. Tuspipe sells this steel as one of its big products. To learn more about the importance of A36 Steel Specifications, it is more comfortable to read about its chemical, mechanical, and physical properties.

Chemical A36 Steel Properties

The A36 steel is also referred to as low-carbon steel. That is, it contains a low level of iron-carbon. It contains approximately 0.25 percent to 0.29 percent of carbon. This little carbon content makes the steel simple to weld and shape, and the steel is not weaker than other steels. Manganese is another ingredient of A36 steel. Its percentage is around 0.80% to 1.20%. Manganese increases the strength of the steel. Phosphorus and sulfur are also present. They are contaminants, and as such, they should be maintained at low levels. Phosphorus is kept at 0.04 or lower, and sulfur is kept at 0.05 or lower. These in excess make the steel brittle and weak. The concentration of silicon is usually not above 0.40%. It helps to remove oxygen from the steel during the production process and also gives some strength. Sometimes copper is added to A36 steel, especially when the steel is to be used outdoors. It is usually at least 0.20 percent copper. This helps the steel to withstand rust and to endure longer in the open air.

A36 Steel Mechanical Properties

The reaction of the steel to force is called the mechanical properties. The strength and ductility of A36 steel are such that it is very convenient to build with. A36 has tensile strength ranging between 400 and 550 megapascals (MPa). This is the force that the steel can withstand before it breaks. It has a yield strength of at least 250 MPa. The force at which the steel starts to bend and not to straighten again is called yield strength. A36 steel is capable of growing at least 20 percent in length before breaking. This is what is called elongation. It shows that A36 steel is not only strong, but it can also resist stress due to its flexibility. A36 steel ranges between 67 and 83 on the Rockwell hardness scale. This does not cut, shape, and weld as easily as some steels. The other valuable characteristic is hardiness. The minimum impact energy in a Charpy V-notch impact test at 20 °C is 27 joules in A36 steel. This means that it is shock-resistant and does not melt at a normal temperature. The modulus of elasticity for A36 steel is about 200 gigapascals (GPa). When the steel has a load placed upon it, it's a test of the steel's rigidity. Its Poisson ratio or stress response is 0.26 to 0.30.

A36 Steel Physical Properties

Physical characteristics describe how the steel will act in the world, i.e., heat, weight, and electricity. A36 steel is about 2.84 pounds per cubic inch. This means that it is dense and stiff, something needed in building firm structures. A36 steel melts at 1425 to 1540 °C. The beautiful mixture of the melting points is what stabilizes the steel at high temperatures. Physical properties describe how the steel would act in the natural environment, i.e., heat, weight, and electricity. A36 steel is around 2.84 pounds per cubic inch. This implies that the steel is very easy to heat. It has a specific heat capacity of approximately 450 to 500 joules per kilogram-kelvin, or the amount of heat energy that the steel can store. The rate of thermal expansion of A36 steel is 11-12 x 10-6/degree C. The amount of expansion of the steel in heat is indicated. The resistivity of the A36 steel is about 0.15-0.20 micro-ohm meters. This actually means that the steel has poor electrical conductivity when compared to aluminum or copper. Finally, A36 steel is a ferromagnetic substance that can be attracted by a magnet. This could be used as an asset in certain industrial uses.

Conclusion

A36 steel has taken the role of being one of the most popular steels in the world. It is an engineering and building material of preference due to its low carbon content, balanced strength, high flexibility, and easy processing. Its chemical properties allow it to be strong and welded, and its mechanical properties allow it to resist force and stress. The physical properties make it strong against weight and heat. To satisfy these needs, Tuspipe has remained to provide A36 steel, and thus it has been a key component in the majority of the projects across the globe.
