I'm being asked to source PN40 steel flanges to material grade RST37 & ASTM A105 in both SO & WN.
The material i have been offered is S235JR?

Can anyone tell me if this is an equivalent spec?

RSt37 is old designation of German structural steel plate and shapes and is not the same as A 105 which is forged carbon steel for piping components,.

S235JR is European designation of structural steel and is similar to RSt37

In european standard EN 10025 you can find the equivalence between EN designation( S235 JR) and german designation (ST 37)
