What is normal strength RE flat bars equivalent steel in GB standard

Temperature has a great influence on the strength of the material, normal strength RE flat bars. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

LNG ships are called "super-refrigerated vehicles on the sea", and their service environment is at a very low temperature of minus 163 degrees Celsius. This requires that the steel for LNG storage tanks must have low temperature resistance, often using Invar steel or 9Ni steel. At present, a complete series of nickel steels such as 0.5Ni steel, 2.5Ni steel, 3.5Ni steel, 5Ni steel, and 9Ni steel have been formed in the field of low-temperature steel. China has also developed relatively mature 3.5Ni steel and 5Ni steel. And 9Ni steel, and successfully used in the construction of low-temperature transport ships.

Cleveland cliffs announced on March 13 that it had completed the acquisition of AK normal strength RE flat bars steel, foreign media reported In the transaction of holding), shareholders of Cleveland cliffs and AK steel respectively voted on the US billion acquisition agreement at their respective shareholders' meeting to complete the resolutions required for the announcement of acquisition of AK steel normal strength RE flat bars at the beginning of the year. The acquisition is Cleveland cliffs' first foray into steel manufacturing.

Perhaps this normal strength RE flat bars explains why Trump has warmed to the idea of constructing a border wall on the U.S. border with Mexico out of steel rather than concrete. In an interview with NPR, Tom Gibson, president and CEO of the American Iron and Steel Institute estimated that the barrier would require a hefty order of normal strength RE flat bars 3 million tons of steel.
