Difference for S355JR+AR and S355JR+N steel plate

Xinsteel Industrial stock European steel specification EN 10025-2 S355JR+AR steel plate and S355JR+N steel plate in Normalized heat treatment in warehouse China.S355JR+AR steel plate supplied under As rolled condition,and S355JR+N steel plate have to be supplying under Normalized condition.Normalizing is the process of heating a material to a temperature above a critical limit and then cooling in open air.After Normalized,S355JR steel plate get the better uniformity,and improved the steel's strength and hardness.


Normally for S355JR steel plate thickness above 40mm,Xinsteel suggest customers choose Normalized heat treatment on steel plates for getting the satisfied final using.Even in EN 10025-2 steel specification,there is no difference requirements for S355JR+AR steel plate and S355JR+N steel plate in chemical composition and mechnical property.
