Mild steel A573 Gr 70 carbon plate chemical composition

S355NL normalized steel has different impact energy requirement for impact tests at different temperature environment. S355NL plate shall be done impacting test in longitudinal direction under -50℃ with the minimum energy 27J. When customers request done charpy_V notch test under -20℃, then the impacting energy shall be above 47J. For the transverse direction, the engery shall be above 16J under the temperature -50℃. The A573 Gr 70 carbon plate, steel Grade S355NL making process shall according to EN10025-1.

The main challenges facing the current low-carbon development of the steel industry are as follows: First, insufficient energy resource endowments, coal and coke account for nearly 90% of energy input. Second, the crude steel output is relatively large, accounting for more than half of the global output. Third, there are a large number of enterprises, with more than 500 enterprises with smelting capabilities, and their structure and level are quite different. Fourth, the carbon emission mechanism is complex, involving multiple carbon emission mechanisms such as energy combustion emissions, indirect emissions corresponding to electricity and heat consumption.

The advantages of A573 Gr 70 carbon plate, medium and thick boiling steel plate: The surface is relatively smooth, the quality is good, and it is easy to process. Because medium and thick boiling steel plate does not have concentrated shrinkage holes, the amount of deoxidizer is small, and boiling steel plate price is lower than other steel plates. Disadvantages of medium and thick boiling steel plate: it has a lot of gas content and impurities, it is not easy to weld, and its bearing capacity is worse than other steel plates, so it is not suitable for parts that need to bear gravity.
