S355NL structural steel vs a573 gr.65 steel what is the hardness?

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of S355NL structural steel vs a573 gr.65 steel, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.

Pakistan's iron and steel industry has suspended S355NL structural steel vs a573 gr.65 steel production and operation since the outbreak, the dawn reported on April 8. Last month, Prime Minister Imran announced a rescue package for the steel industry. Recently, Pakistan's steel industry called for the resumption of production as soon as possible.
