How to identify shoddy A588 Grade K construction steel

In recent years, in line with the development trend of iron and A588 Grade K construction steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A588 Grade K construction steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

S45C steel plate chemical composition: C 0.42~0.48, Si 0.15~0.35, Mn 0.60~0.90, P≤0.030, S≤0.035, Cu≤0.30, Ni≤0.20, Cr≤0.20
Mechanical properties of A588 Grade K construction steel product

There are many advantages of A588 Grade K construction steel, pickling coils. The surface of pickling coil is smooth, and the outside is very beautiful. From the appearance, we can see how the manufacturer's technology is, and it is convenient to use pickling coils in engineering. In addition, the cost can be reduced by using pickling coil instead of cold rolled sheet. The corrosion resistance of pickling coil is better than ordinary steel plate, and its service life is also very long.

Heat treatment is a very important process to improve the performance of A588 Grade K construction steel etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.

A387 Gr 91 Cl 1 alloy steel is an option for use in sour service environments. The material has good weldability and with its heat resistant qualities, the material is a highly versatile steel which can be used in numerous applications.
