S355JR STEEL PLATE,EN10025-2 S355JR
Source:Yusheng steel
EN10025_2 S355JR actually belongs to low alloy steel plate,it is equal to GB Q345B in chinese steel
standard.For the normal thickness,these two steel grades are both owned 345MPa yield strength.This
value is higher than S235JR and Q235B steel plate.
Normally,we used to find the named of S355JR+N, this stand these S355JR steel plates must be done
Normalized heat treatment when rolling for improve the steel strength and weldability.Our mill would
roll S355jr under As_rolled or Control rolled when customers' have not requested any heat treatment
in their P/O.
