EN 10025-2 Grade S355JR normalized or normalized formed (+N)
EN 10025-2 Grade S355JR normalized or normalized formed (+N) introduction
The hot rolled, unalloyed quality steel S355JR is a higher strength fine grained steel for steel structural engineering. Dimensioning advantages in respect to the S235JR due to the by 120 MPa higher yield strength. The steel shows a by 15% higher resistance to mineral wear due to sliding action in comparison to S235JR.
The steel is not intended for heat treatment. Stress relieving annealing is allowed. Products in the delivery condition +N may be hot formed and/or normalized after delivery.
For long products and continuous rolled flats the delivery condition is up to the producer +AR, +N or +M. The delivery condition of four-high rolled sheet is also up to the producer and may be +AR or +N. Both conditions can be ordered.
For this steel is available (mat. no 1.0551, S355JRC) a grade for cold drawing.
