Hi all. Doing some work on steel grades; does anyone know if there is a difference between S275 / S275JR and S275JRH? Likewise for S235 etc.

JR refers to impact test results - 27J at room temperature

PD 6695 is a good non-contradictory complementary information (NCCI) document which is useful to specify steel subgrades. Or P362 Steel Building Design Concise Eurocodes which references the same.

A quick google gives me this:
