Mn content in the en S690QL pdf

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of en S690QL pdf, 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.

Ningbo port has initially formed an all-round three-dimensional collection and distribution network of expressways, railways, aviation, river sea intermodal transport, water to water transfer, etc.

According to the guarantee conditions of delivery, China and some countries divide the ordinary carbon steel into three categories: Class A steel, which only guarantees the mechanical properties, not the chemical compositions； Class B steel, which only guarantees the chemical compositions, not the mechanical properties; special steel (Class C steel), which not only guarantees the chemical compositions, but also the mechanical properties. Class C steel en S690QL pdf is often used to manufacture important structural parts. Density of ordinary carbon steel: 7.85 g / cm3.
