What is the difference between JIS carbon steel SM400A CS plate and carbon steel plates

Compared with the traditional seamless steel pipe, alloy seamless pipe has better performance in all aspects. Because of the addition of various metal elements in the manufacturing, the overall strength of the alloy seamless pipe is larger, stronger and durable, and the service performance and service life of the JIS carbon steel SM400A CS plate, alloy seamless pipe are improved. The alloy seamless pipe is the best choice especially for special environment and high pressure requirements. Because of its high material properties, alloy seamless pipe has good corrosion resistance. It is not easy to be corroded in some special environment, which reduces the cost of the project and has a longer service life.

The latest oil market forecast presented by the International Energy Agency (IEA) in its March report shows that as the impact of COVID-19 spreads globally, travel and broader economic activity are limited, global oil demand is expected to decline in 2020. As the current situation remains uncertain, this has created great uncertainty in assessing the global impact of the epidemic. In the core foundation forecast of the IEA, the sharp shrinkage of China’s oil consumption, coupled with severe disruptions in global tourism and trade, will cause global oil demand to decline for the first time since 2009.

Q345 is a steel material. It is a low alloy steel, with good comprehensive properties, low temperature properties, cold stamping properties, JIS carbon steel SM400A CS plate welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
