In S275J2 grade, J2 means S275J2 low alloy carbon steel plates/sheets should bear a -20 centigrade impact test below zero temperature, which is accustomed to be under the EN10025 designation, and S275 material can be supplied in S355JR, S355J0, S355J2. So far, S355J0 high yield steel plates have been successfully used in the power plant steel sleeve chimney, and fixtures, container, baking equipment, environmental protection, oil derrick and platforms, chemical equipment, desulfurization equipment and construction, etc.
