Q345NQR2 steel specification S355JR, which one has higher tensile strength?

According to the market forecast released by Eurofer on August 5, the output of all Q345NQR2 steel specification steel consumption industries in the European Union will drop by 12.8% in 2020, and rise by 8.9% in 2021. However, the European Union said that the government's "awesome strength" support will reduce the Q345NQR2 steel specification steel consumption intensity in the construction industry significantly less than other industries.

The melting points of vanadium and chromium are relatively high, and the ability to interact with oxygen is also relatively large, so the metal melt should be deoxidized well, and the temperature of the wear plate melt should not be too low, exceeding 1550℃. Boron is an element that is relatively easy to be oxidized and nitridated, so the steel melt must be fully deoxidized and nitrogen fixed before adding. In general wear-resistant plates, Q345NQR2 steel specification, boron is added as a trace element, and the amount used is not very large.
